This product is intended to be operated from a mains power source of nominally 100 V ~ to 230 V ~, 47-63 Hz, or from its internal battery. WARNING: For continued protection against fire hazard, replace only with same type and rating of fuse. Fuse value is T 1A 250V 5 mm x 20 mm. WARNING: To prevent electrical hazards to all personnel, this monitor must be properly grounded. The power cable supplied with this equipment provides for this protection. Do not attempt to defeat this protection by modifying the cable or by using ungrounded adapters. Do not connect to an electrical outlet controlled by a wall switch or dimmer.

WARNING: Electric shock hazard! Do not remove covers or panels. Refer service to qualified service personnel.

WARNING: To avoid electrical shock, disconnect the monitor from its power source before changing fuses.

WARNING: Do not clean monitor while it is on and/or plugged in. WARNING: When attached to other devices, insure that the total chassis leakage currents of all units do not exceed 300µA.

Explosion DANGER: Explosion hazard! Do not use this equipment in the presence of flammable anesthetics.

SAFETY


Patient Connections Leakage current is limited internally by this monitor to less than 10 µA. However, always consider additional leakage current that can be caused by other equipment used on the patient at the same time as this monitor. Carefully route patient cables to reduce the possibility of patient entanglement or strangulation.

Measurements If the accuracy of any measurement does not seem reasonable, first check the patient’s vital signs by alternate means and then check the Model 2000 Pulse Oximeter for proper functioning. Inaccurate measurements may be caused by:

• Incorrect sensor application or use • Significant levels of dysfunctional hemoglobins (e.g., carboxyhemoglobin or methemoglobin) – see note. • Intravascular dyes such as indocyanine green or methylene blue – see note. • Exposure to excessive illumination, such as surgical lamps (especially ones with a xenon light source),

bilirubin lamps, fluorescent lights, infrared heating lamps, or direct sunlight (exposure to excessive illumination can be corrected by covering the sensor with a dark or opaque material)

• Excessive patient movement • Venous pulsations • Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line

The Model 2000 can be used during defibrillation, but the readings may be inaccurate for a short time. Loss of pulse signal can occur in any of the following situations:

• The sensor is too tight • There is excessive illumination from light sources such as a surgical lamp, a bilirubin lamp or sunlight • A blood pressure cuff is inflated on the same extremity as the one with a SpO2 sensor attached • The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia • There is arterial occlusion proximal to the sensor • The patient is in cardiac arrest or is in shock

NOTE: A pulse oximeter measures functional hemoglobin saturation. This is different to an arterial blood gas that measures fractional hemoglobin saturation. Differencies can occur when significant levels of HbCO (carboxyhemoglobin), HbMET (methomoglobin) indocynanine green or methylene blue exist. EMC This equipment has been certified to be protected to emissions and immunity according to IEC-601-1-2.

PULSE OXIMETRY MONITORING


PULSE OXIMETRY MONITORING Overview Pulse oximetry allows you to continuously and noninvasively monitor a patient’s hemoglobin oxygen saturation.The oximetry sensor contains two light emitting diodes (LEDs) that transmit specific wavelengths of light which are received by a photodetector. Oxygen saturated blood absorbs light differently as compared to unsaturated blood. Thus the amount of light absorbed by blood can be used to calculate the ratio of oxygenated hemoglobin to total hemoglobin in arterial blood. The monitor displays this ratio as percent SpO2. Normal values typically range from 95 to 100% at sea level. Principles of Operation The Model 2000 Pulse Oximeter is based on three principles: 1. Oxyhemoglobin and deoxyhemoglobin differ in their absorption of red and infrared light (spectrophotometry). 2. The volume of arterial blood in tissue and the light absorbed by the blood changes during the pulse (plethysmography). 3. Arterio-venous shunting is highly variable and that fluctuating absorbance by venous blood is a major component of noise during the pulse. The Model 2000 Pulse Oximeter as well as traditional pulse oximetry determines SpO2 by passing red and infrared light into a capillary bed and measuring changes in light absorption during the pulsatile cycle. Red and infrared light-emitting diodes (LEDs) in oximetry sensors serve as the light sources, a photodiode serves as the photodetector. Traditional pulse oximetry assumes that all pulsations in the light absorbance signal are caused by oscillations in the arterial blood volume. This assumes that the blood flow in the region of the sensor passes entirely through the capillary bed rather than through any arterio-venous shunts. The traditional pulse oximeter calculates the ratio of pulsatile absorbance (AC) to the mean absorbance (DC) at each of two wavelengths, 660 nm and 940 nm. S(660) = AC(660)/DC(660) S(940) = AC(940)/DC(940) The oximeter then calculates the ratio of these two arterial pulse-added absorbance signals: R = S(660)/S(940) The value of R is used to find the saturation SpO2 in a look-up table built into the oximeter’s software. The values in the look-up table are based upon human blood studies against a laboratory co-oximeter on healthy adult volunteers in induced hypoxia studies.



The Model 2000 Pulse Oximeter assumes that arterio-venous shunting is highly variable and that fluctuating absorbance by venous blood is the major component of noise during the pulse. The 2000 decomposes S(660) and S(940) into an arterial signal plus a noise component and calculates the ratio of the arterial signals without the noise: S(660) = S1 + N1 S(940) = S2 + N2 R = S1/S2 Again, R is the ratio of two arterial pulse-added absorbance signals and its value is used to find the saturation SpO2 in an empirically derived equation into the oximeter’s software. The values in the empirically derived equation are based upon human blood studies against a laboratory co-oximeter on healthy adult volunteers in induced hypoxia studies. The above equations are combined and a noise reference (N’) is determined: N' = S(660) - S(940) x R If there is no noise N' =0; then S(660) = S(940) x R which is the same relationship for the traditional pulse oximeter. The equation for the noise reference is based on the value of R, the value being seeked to determine the SpO2. The Model 2000 software sweeps through possible values of R that correspond to SpO2 values between 1% and 100% and generates an N' value for each of these R values. The S(660) and S(940) signals are processed with each possible N' noise reference through an adaptive correlation canceler (ACC) which yields an output power for each possible value of R (i.e., each possible SpO2 from 1% to 100%). The result is a Discrete Saturation Transform (DSTTM) plot of Relative output power versus possible SpO2 value as shown in the following figure, where R corresponds to SpO2 = 97%. The red light power range is 1mw to 3 mw. The infrared light power range is 0.7mw to 3mw.

The DST plot has two peaks: the peak corresponding to the higher saturation is selected as the SpO2 value. This entire sequence is repeated once every two seconds on the most recent four seconds of raw data. The Model 2000



SpO2 therefore corresponds to a running average of arterial hemoglobin saturation that is updated every two seconds. WARNING: The pulse oximeter should NOT be used as an apnea monitor. WARNING: The pulse oximeter should be considered an early warning device. If a trend towards patient deoxygenation is indicated, blood samples should be analyzed by a laboratory co-oximeter to completely understand the patient’s condition. Caution: Use only sensors specified by Ivy Biomedical Systems, Inc. If you use sensors other than those specified, it might degrade perfomance and could damage the pulse oximeter. Caution: Check the sensor site frequently. Do not allow the sensor to remain on one site for a prolonged period of time, especially when monitoring neonates. Refer to the sensor’s specific instructions. Caution: Never attach a SpO2 sensor on a limb being monitored with a blood pressure cuff or a limb with restricted blood flow. Caution: A poorly applied sensor might give incorrect saturation values. Reapply the sensor. Caution: Choose a site with sufficient perfusion to ensure accurate oximetry values. Caution: Certain nail aberrations, nail polish, fungus, etc. might give inaccurate oximetry values. Remove the nail polish and/or move the sensor to an unaffected digit. Caution: Do not use the Model 2000 Pulse Oximeter or sensors during Magnetic Resonance Imaging (MRI). Pulse Oximetry Sensors To ensure conformance with all safety and performance specifications, use only the Masimo® LNOP pulse oximetry sensors. Monitoring Procedure Use the following procedure for monitoring pulse oximetry: 1. Choose a site that is well perfused and provides proper alignment of the LEDs and receiving photodetector Select a site that has unrestricted blood flow Do not restrict blood flow when securing sensor with tape Select an appropriate sensor and apply it to the patient, following the directions for use provided with the sensor Do not select a site near potential electrical interference (electrical cords, for example). 2. Connect the cable to the monitor’s SpO2 input. 3. Plug the extension cable into the sensor. 4. Use the procedures described in the following sections for alarm limit settings, response mode settings, and enabling or disabling the SpO2 alarm. Alarm Limits 1. Press the MENU key to display the main menu.



2. Select [LIMITS]. 3. Press ALARM RESET to select SpO2 or PULSE PARAMETERS. 4. Use the [HIGH and ] selections to set the high limit. 5. Use the [LOW and ] selections to set the low limit. Each time you press a key, the corresponding limit changes by 1% for SpO2 and 5 BPM for Pulse. The

current settings are shown on the display. 6. Press MENU to return to the normal display. Response Mode Settings 1. Press MENU to display the main menu. Then select [RESPONSE]. 2.

CLEANING AND DISINFECTION The Monitor When necessary, clean the exterior surfaces of the monitor with a cloth or swab dampened with a warm water and mild detergent solution. Do not allow liquids to enter the interior of the instrument. Unplug monitor from mains power. Cleaning and Reuse of Sensors Reusable sensors can be cleaned as follows: 1. Remove the sensor from the patient. 2. Disconnect the sensor from the monitor. 3. Wipe the entire sensor with a 70% isopropyl alcohol pad. 4. Allow the sensor to air dry before returning it to operation. Reattachment of Single Use Sensors Single use sensors can be reapplied to the same patient if the emitter and detector windows are clear and the adhesive still adheres to the skin. The adhesive can be partially rejuvenated by wiping with an alcohol wipe and allowing the sensor to thoroughly air dry prior to replacement on the patient. NOTE: If the sensor fails to track the pulse consistently, the sensor might be incorrectly positioned. Reposition the sensor or choose a different monitoring site. Caution: Do not soak or immerse the sensor in any liquid solution. Do not sterilize any sensor by irradiation, steam, or ethylene oxide.

CLEANING AND DISINFECTION


Patient Cables Patient cables can be cleaned using the following procedure: 1. Remove the cable form the sensor. 2. Disconnect the cable from the monitor. 3.

Apply power with the MAINS power switch and check for the front panel GREEN (AC ON) LED to light. 2. Monitor the +13.7V supply at VB (TP4) with the scope. Adjust RV1 for +13.80 to +13.85V with fully

charged batteries (<.1mV across R10 DMM from F1 back to AGND). 3. Turn the front panel power ON. The voltages should decrease but must be ≥+13.60V. Verify that the front

panel GREEN (ONSTBY) LED lights. 4. Turn the MAINS power OFF. Operate the monitor on battery for approximately 1 minute. Connect the

DMM across R10 (from F1 back to AGND). Turn the MAINS power back ON. Check for the YELLOW (CHARGING LED) to light. The voltage across R10 should be 4.36mV to 5.78mV.

5. While the CHARGING LED is ON, monitor the +12V supply at P105. 6. Turn the front panel power OFF. The voltage at VB (TP4) must be +14.7V to +15.0V. 7. Check the YELLOW (CHARGING LED) to turn off when the voltage at VB (TP4) switches to +13.7

(+13.60V to +13.85V). 8. Turn the front panel power on. Measure the following supplies with the scope referenced to DGND

(TP16): +5V (+4.85V to +5.15V) VCC TP13 B++ (VB≤100mV) TP5 -12V (-11.64V to –12.36V) U13 pin 2

9. Reference the scope to ISOLATED GROUND TP11 and measure the following supplies: +6.2V (+6.16V to +6.35V) TP6 +20V (+26.5V to +32.5V) TP8 +15VI (+14.7V to +15.3V) TP10 -15VI (-14.4V to –15.63V) TP9 +5VI (+4.85V to +5.15V) TP7



10. Turn the rear panel MAINS power off. Disconnect the battery. Connect the power supply to J101. Connect the positive to J101 pin 1 and negative to J101 pin 2. Adjust the external DC supply for +12.0V. Apply power with the front panel power switch.

Connect the scope to VBF (F2 front). Slowly decrease the voltage on the supply until the LOW BATTERY message appears on the display. The voltage should be +10.98V to +11.47V. Continue to decrease the voltage on the supply until the monitor shuts off. The voltage should be +9.60V to +10.26 (just before shut off). Increase the voltage on the supply (DMM) to +12V. The monitor should not turn on.

Audio Tests 1. Set the pulse volume to 100%. Connect the scope to the speaker (+) or JP4. Place the sensor on your finger

or connect it to the simulator. Check for 2.5Vp-p±.3Vp-p. Decrease the pulse volume and make sure the amplitude is gradually reduced to zero.

2. Turn the alarm audio on and set it to 100%. The amplitude at the speaker should be 3.0Vp-p±.3Vp-p.

Decrease the alarm volume to minimum and make sure the amplitude is gradually reduced to .5Vp-p±50mVp-p.

Safety Testing

BE SURE THE FRONT PANEL SWITCH IS SET TO STBY FOR THE FOLLOWING TEST 1. Connect the SpO2 hipot plug to the front panel SpO2 input. Connect the RED lead from the hipot tested to
