Anesthesia Units [10-134]

Anesthesia Units Scope of this Product Comparison

This Product Comparison covers complete anesthesia systems capable of delivering anesthetic agents, ventilating the patient, and monitoring ventilation variables (and possibly gas and physiologic variables). Excluded are separate analyzers designed to measure concentrations of halogenated anesthetics and gases supplied to the unit or to detect levels present in the operating room; also excluded are separate stand-alone physiologic monitoring systems. For information on these devices, see the following Product Comparisons:

These units are also called: anesthesia machines.

Purpose Anesthesia units dispense a mixture of gases and vapors and vary

the proportions to control a patient’s level of consciousness and/or analgesia during surgical procedures. Anesthesia units primarily perform the following four functions:

Provide oxygen (O2) to the patient Blend gas mixtures, in addition to O2, that can include an

anesthetic vapor, nitrous oxide (N2O), other medical gases, and air

Facilitate spontaneous, controlled, or assisted ventilation with these gas mixtures

Reduce, if not eliminate, anesthesia-related risks to the patient and clinical staff

The patient is anesthetized by inspiring a mixture of O2, the vapor of a volatile liquid halogenated hydrocarbon anesthetic, and, if necessary, N2O and other gases. Because normal breathing is routinely depressed by anesthetic agents and by muscle relaxants administered in conjunction with them, respiratory assistance—either with an automatic ventilator or by manual compression of the reservoir bag—is usually necessary to deliver the breathing gas to the patient.

Principles of operation An anesthesia system comprises three basic subsystems: a gas

delivery platform, which creates and delivers gas mixtures and monitors the patient’s respiration (e.g., rate, airway pressure); a data analysis and distribution system, which includes hardware and software that collect and process data and display it to the clinician in a

meaningful way; and, physiologic and multigas monitors (optional in most units), which indicate levels and variations of several physiologic variables and parameters associated with cardiopulmonary function and/or gas and agent concentrations in breathed-gas mixtures. Manufacturers typically offer a minimum combination of monitors, alarms, and other features that customers must purchase to meet standards and ensure patient safety. To meet the minimum standard of care in the United States, the American Society of Anesthesiologists (ASA) states that anesthesia systems must continually monitor the patient’s oxygenation, ventilation, circulation, expired CO2 levels, and temperature. Integrated or stand-alone monitors may be used.

Gas supply and control

Because O2 and N2O are used in large quantities, they are usually drawn from the hospital’s central gas supplies. Cylinders containing compressed O2, N2O, and sometimes other gases are mounted on yokes attached to the anesthesia machine and can serve as an emergency gas supply in case central supplies fail. Cylinder connections should include indexing systems (e.g., specific pattern of pins), which are intended to prevent accidental mounting of a gas cylinder on the incorrect yoke. Each gas entering the system from a cylinder flows through a filter, a one-way check valve, and a regulator that lowers the pressure to approximately 45 pounds per square inch (psi). There is no need for a separate regulator when the central gas supply is used because the pressure is already at about 50 psi.

Anesthesia machines have an O2-supply-failure device and an alarm that protect the patient from inadequate O2 supply. If the O2 supply pressure drops below about 25 to 30 psi, the unit decreases or shuts off the flow of the other gases and activates an alarm.

The flow of each gas in a continuous-flow unit is controlled by a valve and indicated by a flowmeter. The flowmeter can be a purely mechanical arrangement, with a flow tube in which a bobbin moves up and down depending on the flow, or it can be an electronic sensor with an LCD (liquid crystal display). After the gases pass through the control valve and flowmeter, enter the low-pressure system, and, if required, pass through a vaporizer, they are administered to the patient. The N2O and O2 flow controls are interlocked so that the proportion of O2 to N2O can never fall below a minimum value (generally 0.25) to produce a hypoxic breathing mixture. An O2 monitor that is located on the inspiratory side of the breathing circuit analyzes gas sampled from the patient’s breathing circuit and displays O2 concentration in volume percent. O2 monitors should sound an alarm if the O2 concentration falls below the preset limit.

If the flow of anesthetic gases to the patient must be interrupted for any reason, an O2 flush valve can be activated to provide a large flow of central-source O2 to purge the breathing circuit of anesthetic vapors. The O2 flush flow bypasses the flowmeters and vaporizers.

Vaporizers

Because the inhaled anesthetic agents, with the exception of N2O, exist as liquids at room temperature and sea-level ambient pressure, they must be evaporated by a vaporizer. Vaporizers add a controlled amount of anesthetic vapor to the gas mixture. Units capable of accommodating more than one vaporizer at a time (some accept as many as three) should have a lockout mechanism that prevents the use of more than one vaporizer at once. Most vaporizers are either variable bypass (conventional) or heated blender. A few anesthesia units now have a liquid-injector type of vaporizer. This vaporizer is electronically controlled and injects the liquid anesthetic agent directly into the stream of gases.

Variable bypass and heated blender vaporizers are concentration calibrated and thus can deliver a preselected concentration of vapor under varying conditions. In a variable bypass vaporizer, such as one used for enflurane, isoflurane, halothane, or sevoflurane, a shunt valve divides the gas mixture entering the vaporizer into two streams; the larger stream passes directly to the outlet of the vaporizer, while the smaller stream is diverted through an internal chamber in which vapor fills the space over the relatively volatile liquid anesthetic. The vapor mixes with the gas of the smaller stream, which then rejoins the larger stream as it exits the vaporizer. In a mechanically controlled variable-bypass vaporizer, a bimetallic thermal sensor that regulates the shunt valve to divert more or less gas through the chamber compensates for temperature changes that affect the equilibrium vapor pressure above the liquid. Each variable bypass vaporizer is specifically designed and calibrated for a particular liquid anesthetic.

The heated blender vaporizer was introduced for use with the anesthetic agent desflurane. In this type of vaporizer, desflurane is heated in a sump chamber. A stream of vapor under pressure flows out of the sump and blends with the background gas stream flowing through the vaporizer. Desflurane concentration is controlled by an adjustable, feedback-controlled metering valve in the vapor stream.

Measured-flow vaporizers (also known as copper kettle or flowmeter-controlled) are considered largely obsolete but may still be in limited use in some developing countries. These vaporizers are not concentration calibrated; instead, a measured flow of carrier gas is used to pick up anesthetic gas.

Draw-over vaporizers are sometimes used by the military in the field, as well as in situations or countries in which pressurized gas sources are unavailable. Such units offer low resistance to gas flow and are relatively simple.

Ventilation

Manual ventilation, which requires that an operator manually squeeze the reservoir bag for each patient breath, can be tiring during long procedures and can compete with other tasks; therefore, an automatic ventilator is generally used to mechanically deliver breaths to the patient. These ventilators use a bellows or piston in place of the manually compressed reservoir bag. The ventilator forces the anesthesia gas mixture into the patient’s breathing circuit and lungs and, in a circle breathing system, receives exhaled breath from the patient as well as fresh gas. The anesthetist can vary the volume of a single breath (tidal volume) and the ventilation rate, either directly by setting them on the ventilator or indirectly by adjusting parameters such as the duration of

Figure 1. Continuous-flow anesthesia system

Anesthesia Units


inspiration, the inspiratory flow, and the ratio of inspiratory to expiratory time. The ventilatory pattern is adjusted to the varying needs of the patient.

Minute ventilation, the total volume inspired or expired during one minute, can be evaluated as the product of the expired tidal volume and the ventilation rate. It requires careful monitoring, not only because it is physiologically important to the patient, but also because it can indicate malfunctions of the ventilation delivery system (e.g., leaks in the breathing circuit). The expired tidal volume can be measured with a flowmeter, with a spirometer, or (most commonly) with a sensor placed in the expiratory circuit. Most ventilators are capable of providing controlled ventilation and can maintain a positive airway pressure during the expiratory phase of the breath (positive end-expiratory pressure [PEEP]). Many ventilators can be equipped with modes that permit spontaneous breathing during mechanical ventilation.

Breathing circuits

Most anesthesia systems are continuous-flow systems (see Figure 1), that provide a continuous supply of O2 and anesthetic gases. There are two basic types of breathing circuits used in these systems: the circle system and the T-piece system (see Figure 2), each of which can assume various configurations. (A common configuration of the T-piece system is the Bain modification of the Mapleson D system.) A higher proportion of anesthetic gases is rebreathed in the circle system, which uses check valves to force gas to flow in a loop and returns expired gases (minus the CO2), plus fresh gas, to the patient. In the T-piece circuit, most of the exhaled gas is vented out of the system, and the portion rebreathed depends on the fresh-gas flow rate.

In the circle system, fresh gas from the anesthesia machine enters the inspiratory limb of the breathing circuit and mixes with gas in the system before the resulting mixture flows through a one-way valve to the patient. Expired gas flows from the patient through a second (expiratory) limb of the circuit, passing another one-way valve, into either a reservoir bag or a ventilator.

When positive pressure is generated in the system, either by a manual squeeze of the reservoir bag or by compression of the bellows or piston by a mechanical ventilator, collected gas that does not escape via an adjustable pressure-limiting (APL) valve to the scavenging system is driven through a CO2 absorption canister where CO2 is removed from the gas before it is returned to the patient. In circle breathing systems, a fresh-gas flow of 1 L/min or less is typically considered low-flow anesthesia (4 to 10 L/min is typically considered the usual fresh-gas flow rate). A fresh-gas flow of 0.5 L/min is generally considered minimal-flow anesthesia. In situations in which the cost of anesthetic agents is high, low-flow anesthesia may be the preferred option.

Machines with a T-piece design have corrugated tubing in which fresh gas and some expired gas mix before entering the patient at each inhalation. Partial rebreathing is controlled by the supply rate of fresh gas, and the exhaled anesthetic mixture leaves the circuit through an APL valve. Elimination of rebreathed CO2 depends on fresh-gas flow and occurs in direct proportion to that flow. This system, although adaptable to a variety of anesthetic procedures, is used most often in pediatric anesthesia.

Circle systems offer advantages over T-piece systems in that they conserve a greater proportion of the anesthetic gases and conserve body heat and moisture from the patient. The advantages of T-piece systems

Figure 2. Examples of breathing circuits

Anesthesia Units


include a lower circuit compliance, easier circuit sterilization (when reusable circuits are used), and a less complex design requiring fewer valves and no CO2 absorber (although one can be used with it).

Because excess pressure imposed on the patient’s lungs can cause serious lung damage, either an APL valve (during manual ventilation) or a valve in the ventilator (during automatic ventilation) allows excess gas to escape when a preset pressure is exceeded. There are two types of APL valves: spring-loaded and needle valves. The spring tension in spring-loaded APL valves can be adjusted to control the pressure at which the valve will open. At lower pressures, the valve is closed. The pressure in the breathing system maintained by the needle valve depends on the flow through the valve. Therefore, when the valve is not fully closed, gas will always leak from the system. The minimum exhaust pressure required to refill a ventilator bellows is usually 1 to 2 cm water (H2O); for maximum pressure, both types of valve are fully closed. Because many APL valves do not have calibrated markings, the anesthetist must adjust them empirically to give a desired peak inspired pressure. Circle systems and T-piece systems also include a pressure gauge for monitoring circuit pressure and setting the APL valve. An electronically controlled, settable, and calibrated APL valve is available on some anesthesia machines.

Scavenging system

A scavenging system captures and exhausts waste gases to minimize the exposure of the operating room staff to harmful anesthetic agents. Scavenging systems remove gas by a vacuum, a passive exhaust system, or both. Vacuum scavengers use the suction from an operating room vacuum wall outlet or a dedicated vacuum system. To prevent positive or negative pressure in the vacuum system from affecting the pressure in the patient circuit, manifold-type vacuum scavengers use one or more positive or negative pressure-relief valves in an interface with the anesthesia system. In contrast, open-type vacuum scavengers have vacuum ports that are open to the atmosphere through some type of reservoir; such units do not require valves for pressure relief.

Passive-exhaust scavengers can vent into a hospital ventilation system (if the system is the nonrecirculating type) or, preferably, into a dedicated exhaust system. The slight pressure of the waste-gas discharge from the anesthesia machine forces gas through large-bore tubing and into the disposal system or directly into the atmosphere.

Monitors and alarms

Anesthesia systems incorporate a set of equipment-related monitors, including those for airway pressure, expiratory volume, and inspired O2 concentration. They can also include exhaled gas monitors, such as those for CO2 concentration, N2O concentration, and agent concentration, or physiologic monitors such as those for blood O2 saturation by pulse oximetry, electrocardiogram, invasive and noninvasive blood pressure, and temperature.

Anesthesia systems are typically configured with respect to their monitors in one of two ways: as modular systems or as preconfigured systems. In the modular approach, an anesthesia machine with a basic set of equipment monitors (usually airway pressure, inspired O2 concentration, and expired volume) is used as a physical platform for the system. Additional physiologic monitors, individually or in a monitoring system (with its own display and alarms), along with other devices as needed, are obtained separately and added to the system. The preconfigured approach involves a more completely integrated, manufacturer-assembled system that already includes all physiologic and equipment monitors and displays in a turnkey unit.

Integration of the information and alarms from each of the monitors into as few displays as possible (preferably 1 or 2) has become very important. An integrated display gives the anesthetist a single point of reference for a wide variety of equipment and physiologic information. Anesthesia machines that lack integrated alarms can sometimes cause confusion among anesthetists and operating room teams by sounding numerous alarms simultaneously. In an integrated system of information and alarms, visual alarm messages appear on a central display; furthermore, audible and visual alarms are prioritized so that the more urgent alarm sounds and visual signals are associated with the more vital monitored variables.

Anesthesia Units


An anesthesia workstation is designed to centralize system control and to integrate the display of information. This involves continuous acquisition, recording, and presentation on a central display of selected monitored physiologic and equipment variables (in real time or using historical trends) along with limit settings and the status of all alarms, plus explanatory messages.

Several models exist to predict the level of wakefulness in anesthetized patients, such as the Ramsay Scale and the Modified Observer’s Assessment of Alertness/Sedation Scale. However, in lieu of a direct method of monitoring brain activity during surgery, users may rely on indirect means of assessing consciousness, such as blood pressure and vital signs. According to proponents, one indirect method, level-of-consciousness monitoring (e.g., Bispectral Index [BIS], Physiometrix’s Patient State Index), measures the effectiveness of painkilling agents while ignoring the sedative and paralytic elements that constitute a significant portion of anesthetic agents. Some anesthesia units may incorporate this technology as an additional tool to monitor the patient. Level-of-consciousness monitors use a metered scale (0 to 100) to indicate the degree of patient wakefulness based on collected and processed data. A digital meter indicates the number on the scale that corresponds to the patient’s degree of wakefulness, with a higher number representing a higher degree of consciousness and awareness of sensation despite the presence of anesthetic agents. One supplier offers an Entropy module that provides information on the central nervous system during general anesthesia. The information is acquired based on the acquisition and processing of raw electroencephalogram (EEG) and frontalis electromyography (FEMG) signals using a proprietary algorithm. The Entropy module is designed to assist clinicians in delivering the appropriate amount of anesthetic agents. ASA states that there is not enough evidence to warrant mandatory use of these technologies for patients under general anesthesia. However, ASA states that it may be useful for at-risk patients to be monitored for intraoperative awareness. For additional information, visit ASA’s Website at http://www.asahq.org/.

Automated anesthesia record keepers/anesthesia information management systems

Automated anesthesia record keepers (AARKs) are available either as an option on some anesthesia units or from third-party suppliers. They are used for collecting data from electronic ventilation and monitoring equipment that has appropriate outputs. Vital signs such as blood pressure, heart rate, end-tidal CO2, and oximeter values are recorded at specific intervals and plotted in graph form. Drug dosages, lab data, intraoperative events, and gas delivery rates are entered into the system either manually or by some semiautomated means; comments can also be entered directly onto the record. An AARK produces a formatted hard copy of the anesthesia record for the patient’s files. Gathering and storing such data can expedite individual patient management and billing, quality assurance, critical incident analysis, and teaching. However, automated record keeping has not achieved wide acceptance, in part because of many clinicians’ concerns about misleading artifacts being entered into the record, hospital personnel’s resistance to change, and the cost of implementing an automated record keeper.

An anesthesia information management system (AIMS) can receive, analyze, store, and distribute information relating to the clinical and administrative management of anesthesia. Information can be collected from numerous sources associated both directly with anesthesia administration (e.g., an AARK system) and indirectly with the surgical procedure (e.g., preoperative evaluation, laboratory, and pharmacy records). Long-term storage capabilities aid in quality assurance and anesthesiology research. Some systems may also incorporate administrative management tools such as room scheduling and patient billing. (For further information, see the Product Comparison titled Information Systems, Anesthesia.)

Reported problems Problems have been reported in all areas of anesthesia systems. Because patients under general anesthesia

depend entirely on others for life support, errors caused by machine failure, faulty adjustments, or the operator

can be critical. Pre-use checklists, regular inspections, and preventive maintenance are critical to minimizing anesthesia unit hazards.

One of the greatest dangers of general anesthesia is a lack of O2 delivered to the patient (hypoxia), which can result in brain damage or death. Conversely, the administration of O2 in a concentration of 100%, even for a short duration, may be toxic. Inhalation of 100% O2 may cause resorption atelectasis. The danger of inhaling 100% O2, even for a short duration, is particularly acute in neonatal anesthesia, potentially causing retrolental fibroplasia and bronchopulmonary dysplasia. Inadequate O2 delivery can be caused by any number of conditions, including disconnection of the patient from the breathing circuit; accidental movement of the O2, N2O, or other gas flow control setting knobs; changes in the patient’s lung compliance; and gas leaks. One common safety measure is the inclusion of an O2 monitor and a CO2 monitor or an expired volume alarm (in an anesthesia unit with an ascending bellows) in the anesthesia system. An O2 monitor warns of inadequate O2 concentration in the inspiratory limb. A CO2 monitor or a spirometer alarm (in an anesthesia unit with an ascending bellows) in the breathing circuit can alert the anesthetist to inadequate ventilation such as that caused by a disconnection.

ECRI Institute has investigated incidents of patient exposure to carbon monoxide (CO) during the administration of inhaled anesthetics through semiclosed circle anesthesia systems. Once in the blood, CO binds tightly with hemoglobin, forming carboxyhemoglobin and diminishing the ability of hemoglobin to transport and release O2. A reaction between halogenated anesthetic agents and commonly used CO2 absorbents can produce CO if the CO2 absorbent is excessively dry. Excessive dryness can occur when (1) an anesthesia machine has been idle (e.g., over a weekend) and (2) there is a continuous flow of medical gas (which is very dry) through the CO2 absorber. When dry, the absorbent becomes highly reactive in the presence of certain halogenated agents, resulting in the production of CO as the agent flows through the machine’s CO2 absorber. ECRI Institute recommends that the absorbent material in both canisters of an absorber be replaced whenever there is reason to believe that a machine has been left idle with gas flowing for an undetermined time. Fresh absorbent materials are sufficiently hydrated and normally remain hydrated by exhaled water vapor in the circle system, thereby preventing reaction with halogenated agents. See the Health Devices 2000 Nov citation in this report.

Some anesthesia system malfunctions can cause delivery of gas with excessive CO2 concentration, an inadequate or excessive amount of anesthetic agent, or dangerously high pressure. Hypoventilation, compromised cardiac output, air in the pleural cavity (pneumothorax), and asphyxiation are possible consequences of such problems.

Improperly calibrated vaporizers can result in the delivery of the wrong concentration of anesthetic agent to the patient. Removing some vaporizers from the anesthesia machine and transporting them can disturb their calibration and could eventually cause delivery of too much or too little anesthetic. However, many “tip-proof” vaporizers have been released to reduce calibration errors. The output of an anesthesia vaporizer should be tested each time the vaporizer is removed from a system and each time it is returned to service. Each vaporizer should be inspected and the calibration verified at least twice a year.

Contamination of any part of the anesthesia breathing circuit, including the breathing tubes, Y-connector, face mask, and reservoir bag, may lead to nosocomial infections. Reported cases include infections of the upper respiratory tract or the lungs and, in one instance in Australia, transmission of hepatitis C. The Centers for Disease Control and Prevention (CDC) and the American Association of Nurse Anesthetists recommend single use of disposables or high-level disinfection of reusables or disposables between patients to prevent cross-contamination. There has been some controversy concerning the use of disposable bacteria filters to prevent patient cross-infections (Dorsch and Dorsch; Hogarth; Komesaroff; Snowdon). CDC has not made a definitive recommendation concerning the use of bacterial filters with anesthesia machines. Possible hazards, such as the increased impedance to gas flows and obstruction of the circuit, are associated with these filters. Because many viruses are difficult to culture, the efficacy of viral filters that attempt to reduce viral contamination of breathing systems is not established. Frequent replacement of disposable filters can prevent inadequate gas delivery due to clogging. Some filters can be sterilized and reused.

Anesthesia Units


The piping connections for O2 and N2O within the hospital walls can be accidentally interchanged during installation or repair of medical gas systems, potentially causing patient injury or death. After any such work, careful inspection and testing with an O2 analyzer are vital. Gas lines should also be checked for liquid, gaseous, solid particulate, and microorganism contamination after installation or repair and periodically thereafter.

In many countries, a diameter index safety system (DISS) is used to prevent the connection of gas hoses from the machine to the wrong wall outlet, and a pin index safety system is used to prevent the connection of the wrong cylinders to the yokes in the anesthesia machine. The pin index safety system employs pins protruding from the yoke that correspond to holes in a specific type of gas cylinder post. Only a cylinder post with the corresponding holes can fit properly onto the yoke. ECRI Institute has seen instances of improper connections in which damaged pins allowed users to force the wrong cylinder into place. ECRI Institute recommends that damaged indexing components should never be used.

Faulty or inoperative scavenging systems are responsible for most anesthetic gas pollution in the operating room; other causes include improper anesthesia administration technique and leaks in anesthesia equipment. Common sources of leaks include hose connectors, the CO2 absorber, the APL valve, and the endotracheal tube or mask. Current scientific and epidemiologic studies have shown that exposure to trace levels of anesthetic gases continually present in the operating room can cause adverse health effects in operating room personnel, such as an increased incidence of spontaneous abortion and congenital anomalies in offspring. In addition, trace gas levels in the air may have a slight anesthetizing effect on the anesthetist and surgeon.

Inadequate evacuation of some scavenging systems can cause pressure to build up in the breathing circuit, with the potential for pneumothorax.

Another common problem is circuit obstruction due to the presence of a foreign object (e.g., needle caps) or a manufacturing defect. This problem occurs most often when a pre-use check is omitted.

As mentioned previously, anesthesia units that lack integrated monitors and alarms can cause confusion by sounding numerous alarms simultaneously. While integrated monitors and alarms are becoming more widespread, both modular and integrated systems are subject to the confusion caused by false alarms. A false alarm, caused by accidental patient movement or other nonphysiologic reasons, can confuse operating room staff and possibly draw attention away from other alarms that may truly indicate a change in the patient’s physiologic condition. Ensuring that the alarm limits are properly set and positioning sensors and electrodes in such a way as to minimize artifacts can reduce the incidence of false alarms. ECRI Institute recommends that users do not set physiologic alarm limits below normal values in order to reduce nuisance alarms.

The magnetic fields created by magnetic resonance imaging (MRI) equipment may interfere with the function of conventional anesthesia units and electronic monitoring equipment when used in proximity to such equipment. Conversely, magnetic materials and electronic monitors may interfere with MRI scanner function and degrade image quality. Many MRI-compatible anesthesia machines have restrictions or limitations to their use in the MRI environment. If they are not used in accordance with these restrictions/limitations, MRI-compatible devices can pose the same types of hazards in the MRI environment as devices that are not MRI compatible. For instance, if some MRI-compatible devices are positioned closer to the MRI unit than is specified by the device supplier, they may not function properly or be attracted to the magnet. Some MRI-compatible devices that come into physical contact with a patient, if used inappropriately, can cause burns (or the sensation of heat) to a patient. The hazards posed by the inappropriate use of MRI-compatible devices in the MRI environment can cause injury to the patient or staff and/or damage to equipment (e.g., the MRI-compatible device, the MRI unit itself). A few suppliers offer MRI-compatible anesthesia machines, and a line of MRI-compatible monitors is available.

Anesthesia Units


Purchase considerations

ECRI Institute recommendations

Included in the accompanying comparison chart are ECRI Institute’s recommendations for minimum performance requirements for anesthesia units. The recommendations are listed in two categories: basic and high performance.

ECRI Institute considers certain minimum safety measures necessary for all anesthesia units. Among these measures are O2 fail-safe and hypoxic mixture fail-safe systems, gas cylinder yokes for O2 if central supplies fail, and an internal battery (for units with automatic ventilators) capable of powering the unit for at least 30 minutes.

The unit must be able to measure O2 concentration, airway pressure, and either the volume of expired gas or the concentration of expired CO2 (ETCO2). (Note: ASA recommends monitoring of ETCO2 in all intubated patients; this can be accomplished by the anesthesia unit or by a separate device [e.g., capnograph, multigas monitor].)

Gas cylinders should be attached through hanger yokes with the proper pin index safety system and check valves. Each pipeline gas cylinder supply should have a pressure gauge with scale numbers large enough to be easily read. Gas hoses and machine receptacles should use DISS fittings to prevent misconnection.

It is advantageous if the anesthesia unit accepts medical-air input to allow delivery of either air and/or N2O as the gas carrier. In the event of a partial or complete loss of O2 supply, an undefeatable audible alarm should activate and the flow of N2O gases should automatically shut off or decrease proportionately to the flow of O2 to prevent a hypoxic condition. Also, flows and the mixture ratios determined from flowmeter settings should be accurate to within 10% of set values. Anesthetic vapor concentration delivered to the common gas outlet should be accurate to within 0.2% vapor concentration of agent or 10% of the set value (whichever is greater) at any gas flow. It is preferable that ventilation rate and PEEP values be monitored. It should not be possible to silence or disable a ventilator monitor alarm for longer than two minutes.

Units should have a power-loss alarm, and the battery backup should have an automatic low-battery alarm. All units should include a backup battery to guard against power loss. The anesthesia unit should automatically switch to the internal battery if line power is interrupted; also, the loss of line power should be accompanied by an alarm. The battery should also operate the anesthesia unit and integral monitors for at least 30 minutes. A low-battery alarm should visually and audibly indicate when the battery voltage falls to a level below which the unit may fail to perform satisfactorily. The battery should not require more than 16 hours to recharge completely after depletion.

High-performance systems are distinguished largely by their ability to serve a wide range of patients and to operate with little or no supplemental equipment. Features that make this possible include ventilator modes and tidal volume ranges suitable for neonates and adults, as well as integrated gas and sometimes physiologic monitoring. (Although most models tend to include only a small number of standard ventilation modes, additional modes can typically be added via software upgrades following purchase.) High-performance units generally include more automated features, including storage of trends and self-tests at the beginning of each procedure.

Basic systems include only the most vital monitoring capabilities (i.e., O2 and CO2 volumes or pressures) and have only one or two automatic ventilator modes. When equipped with appropriate stand-alone monitors, these units are adequate for treatment of most patients but may remain ill-suited for use on neonates and very sick patients, as well as for monitoring-intensive procedures (e.g., certain types of cardiac surgery). These fundamental systems may also include units designed for military or field use, which often lack ventilators and pipeline gas inlets.

Anesthesia Units


Other considerations

Some anesthesia units require stand-alone physiologic monitors (modular approach) and/or anesthetic agent monitors, while others have integrated monitors (preconfigured approach). The advantages of preconfigured monitoring include convenience and electronically integrated displays and prioritized alarms. Modular systems can be less expensive than preconfigured systems, especially if the facility already owns the monitors.

Hospitals can purchase customized modular systems assembled from standard components, or they can assemble their own modular systems. These systems must meet all national and regional safety standards. Advantages of the modular approach include flexibility in choosing and upgrading monitors and ease of service; drawbacks include assembling a system that may not be successfully integrated and thus has multiple alarms and/or displays.

Anesthesia units and patient monitoring systems should be carefully chosen to ensure that all essential monitoring functions recommended by the American Society of Anesthesiologists are obtained and to ensure optimal integration and an adequate standard of care. For legal reasons, the level-of-monitoring and anesthesia-delivery capabilities for each anesthesia station should be uniform so that all patients receive the same standard of care for the same surgical procedures.

Integrated anesthesia workstations, along with the gas/vapor dispensing subsystem and individual physiologic and equipment monitors, may also include a device for automatically dispensing injectable drugs. Consequently, the anesthesia workstation can be viewed as an integrated monitoring system that dispenses anesthetic drugs.

Hospitals should also consider the standardization of anesthesia equipment; that is, purchasing systems that are compatible with equipment already in operating rooms or other areas of the hospital (e.g., intensive care units). The purpose of standardization is to allow a reduced parts inventory, minimize the number of suppliers and service personnel, and reduce confusion among the staff.

Pulse oximetry is considered a standard of care for monitoring arterial O2 saturation in the operating room during procedures requiring anesthesia and in intensive care units and recovery.

Pulse oximeters noninvasively measure O2 saturation of blood hemoglobin (SpO2) and, along with O2 monitors and CO2 monitors, are increasingly being required for anesthesia units by state law. Some U.S. states have specified their own requirements for anesthesia units. Hospitals should check with their state’s department of health for any regulations that may apply to their area. Pulse oximeters provide a spectrophotometric assessment of hemoglobin oxygenation by measuring light transmitted through a capillary bed, synchronized with the pulse. The detection system consists of single-wavelength LEDs (light-emitting diodes) and microprocessors located within a sensor. For more information on pulse oximeters, see the Product Comparison titled Oximeters, Pulse.

CO2 monitors measure end-tidal CO2 and can help identify leaks and misconnections as well as indicate when the trachea has not been properly intubated.

Many features of anesthesia systems are optional, allowing hospitals to choose those that best fit their needs. Among anesthesia units with essentially equivalent mechanical gas/vapor dispensing subsystems, the monitors included in the system and the ways in which information is integrated and displayed are often the primary distinguishing features.

Environmental considerations

As a result of increasing concerns over the environment and the conservation of resources, many manufacturers have adopted green shipping and production methods, as well as features that improve the energy efficiency of their products or make them more recyclable. In addition, healthcare facilities and device manufacturers have begun to adopt green initiatives that promote building designs and work practices that reduce waste and encourage the use of recycled materials.

Anesthesia Units


Some manufacturers may offer a xenon gas option. Xenon gas is not considered to be a greenhouse gas and is regarded as environmentally friendly, unlike nitrous oxide. Green shipping methods should be considered. At least one manufacturer ships anesthesia units on reusable wooden palettes. Facilities should also look for manufacturers who offer take-back programs on units.

Cost containment

Because anesthesia systems entail ongoing maintenance and operational costs, the initial acquisition cost does not accurately reflect the total cost of ownership. The anesthetic agents are the biggest ongoing expense associated with anesthesia units. Therefore, a purchase decision should be based on issues such as life-cycle cost (LCC), local service support, discount rates, and non-price-related benefits offered by the supplier.

An LCC analysis should be conducted to determine the cost-effectiveness of all units that meet users’ needs. Although costs associated with many of the following may be similar for a number of anesthesia units, they

should still be carefully considered to determine the total LCC for budget purposes: Maintenance, service, and inspection Accessories, such as monitoring equipment, necessary to comply with standards Optional accessories Vaporizers (some have been offered at discounted prices or at no cost upon the introduction of a

may also be available from a third-party organization. The decision to purchase a service contract should be carefully considered. Most suppliers should provide routine software updates, which enhance the system’s performance, at no charge to service contract customers. Purchasing a service contract also ensures that preventive maintenance will be performed at regular intervals, thereby eliminating the possibility of unexpected maintenance costs. Also, many suppliers do not extend system performance and uptime guarantees beyond the length of the warranty unless the system is covered by a service contract. Hospitals that plan to service their anesthesia units in-house should inquire about the availability and cost of service training and the availability and cost of replacement parts.

ECRI Institute recommends that, to maximize bargaining leverage, hospitals negotiate pricing for service contracts before the system is purchased. Additional service contract discounts may be negotiable for multiple-year agreements or for service contracts that are bundled with contracts on other similar equipment in the department or hospital. Discounts will depend on the hospital’s negotiating skills and knowledge of discounts offered to other customers, the system configuration and model to be purchased, previous experience with the supplier, and the extent of concessions granted by the supplier, such as extended warranties, fixed prices for annual service contracts, and guaranteed on-site service response. Buyers should make sure that applications training and service manuals are included in the purchase price of the system. Some suppliers offer more extensive on- or off-site training programs for an additional cost. For customized analyses and purchase decision support, readers should contact ECRI Institute’s SELECTplus™ Group.

Anesthesia Units


Stage of development Efforts to improve the design of anesthesia units center on gas supply and proportioning systems, gas

monitors, ventilators, vaporizers, and data-handling (display, processing, and reporting) software. There is also an effort to decrease the overall size of anesthesia units.

Although anesthesia systems are fundamentally unchanged, manufacturers have made a handful of improvements, including:

The introduction of low-volume breathing circuits The increasing availability of ventilation modes Increasing automation of pre-use checks
