5.11.2 Pre-use check
1
、
Before connecting the IRMA airway adapter to the breathing circuit, verify the O
2
calibration by checking that the O
2
reading on the monitor is correct (21%). See 5.8.3
for instructions on how to perform room air calibration.
2
、
Verify that there has not been any accumulation of gas between the IRMA sensor head
and the BLUEYE windows by checking that the CO
2
and Agent readings on the
monitor are correct before connecting a patient to the breathing circuit.
3
、
Perform the tightness check of the patient circuit with the IRMA sensor head
snapped on the IRMA airway adapter.
4
、
Check that the connections have been made correctly by verifying an actual gas
waveform on the monitor display.
5.11.3 Room Air Calibration
Room air calibration of the oxygen sensor will be performed automatically at regular
intervals whenever the IRMA sensor head is disconnected from the IRMA airway adapter.
If the IRMA sensor is kept in operation for a long time period without being
disconnected from the airway adapter, or if the operating temperature for the oxygen
sensor changes significantly, the IRMA sensor will indicate that a new room air calibration
is required and a message will appear on the monitor.
Use the following procedure to perform a room air calibration of the oxygen sensor:
1. Disconnect the IRMA sensor from the airway adapter.
2. Wait until the LED starts blinking with red light.
3. Snap the IRMA sensor back on the airway adapter.
4. Check that the LED turns green.
5. Check that the O
2
reading on the monitor is 21%.
