MACS CPAP System
Self Guided Tour
Program Objectives
This program is a self guided tour of the
MACS CPAP System.
At the end of this tour you will be able to:
Describe the main operating features of MACS Identify the controls and connections Describe the patient circuit Set-up MACS for patient operation Define various clinical environments for CPAP application Clean and maintain the MACS
Features and Controls – Rear Panel
Driving Gas Input
Connection for 50 psi oxygen source gas
Always use a high flow gas source (pressure take-off) that can provide 55 + 15 psi pressure at a minimum of 40 L/min
Features and Controls – Rear Panel
Air Entrainment
Ambient air is entrained for internal gas mixing
External housing contains air filter
Air filter replacement is part of the preventative maintenance
Features and Controls – Front Panel
CPAP Control
Adjusts the CPAP from 0 to 20 cm H2O
Automatic sensitivity Flow adjusts automatically
to meet patient demand up to 140 L/min
Oxygen concentration is maintained at set % Oxygen control
Features and Controls – Front Panel
% Oxygen Control
Delivered oxygen choice 65% 100%
Sets the spontaneous breath oxygen concentration
Features and Controls – Front Panel
Pressure Gauge
Shows pressure in patient circuit at the output of MACS
Gives an indication of patient effort
Features and Controls – Front Panel
Circuit Connection 1
Connection for the large bore hose of the patient circuit
Features and Controls – Front Panel
Circuit Connection 2
Patient circuit small hose connection
Connects to the expiratory valve on the patient circuit
Patient Circuit
Patient circuit is a disposable, single limb system; Both hoses attach to the front of MACS Patient end connects for clinical intervention
Directly to an endotracheal tube (invasive) Resuscitator face mask (noninvasive)
Use 90 degree elbow to connect bacteria filter for operator protection
Patient Circuit
Use only Airon Corporation patient circuits; Calibration of the CPAP control is based upon the Airon
patient circuit Using other manufacturers circuits may cause
errors in pressure delivery high expiratory flow resistance interference with CPAP sensitivity increased oxygen usage
Program Objectives
MACS CPAP System self guided tour, objectives completed so far:
Describe the main operating features of MACS Identify the controls and connections Describe the patient circuit
With an understanding of MACS’s capabilities, let’s look at patient application.
Patient Application
Initial Set-up Attach Airon patient circuit
to MACS Attach a high pressure
oxygen hose to the rear of MACS
Attach this hose to the oxygen source
Patient Application
Set % Oxygen Control Set % Oxygen control to the desired
oxygen level All breaths receive set oxygen level
+ 10% Oxygen tank time doubles with 65% Caution - with rapid, large tidal
volumes on 100% oxygen, the actual delivered percentage might be slightly less than 100%
Patient Application
Start CPAP Turn on oxygen source Attach patient breathing
circuit to the patient using either a mask or endotracheal tube
Adjust the CPAP control to the level desired
If the patient is not attached to the circuit, or there is a large leak, a high flow of gas will occur
Patient Application
Monitor patient Assess per your protocol
patient breathing rate comfort oxygenation CO2
Clinical Issues
Pediatric Support
MACS is safe for pediatric - adult patients
Use the lowest possible settings Monitor closely for patient synchrony
Clinical Issues
Providing nebulized medications
A medication nebulizer may be placed between the patient connection and the patient
Patient will inhale medication during every breath and exhale back out through patient circuit
Filters may be added for personnel safety
Clinical Issues
CO2 Monitoring
Any type of CO2 analyzer may be used
Inline style analyzers should be place between the patient circuit connection and the patient
Place the sampling tube of sidestream analyzers under the patient mask
Clinical Issues
Altitude Operation
MACS can be used for air transports in unpressurized cabins up to 15,000 feet
Pressure settings will not change as altitude changes
Patient Safety
Patient Safety Features
Internal Safety Pressure Release – limits circuit pressure to 40 cm H2O
Anti-Suffocation System – in the event of device malfunction, an internal valve will allow ambient air to enter the patient circuit
Cleaning and Maintenance
Clean MACS between patients using a soft cloth and a mild detergent / disinfectant
Do not immerse MACS in water Patient circuit is disposable, single use
application and should not be cleaned, disinfected or reused
MACS should receive preventative maintenance every 2 years
Program Objectives
MACS CPAP System self guided tourcompleted; you should now be able to:
Describe the main operating features of MACS Identify the controls and connections Describe the patient circuit Set-up MACS for patient operation Define various clinical environments for CPAP application Clean and maintain MACS
Next Step – consider reviewing the MACS Case Study and completing the competency evaluation
