Warning
Use of high frequency electrosurgical equipment in the vicinity of IRMA may produce
interference and cause incorrect measurements.
NOTE:
Do not apply tension to the sensor cable.
NOTE:
Do not operate the IRMA probe outside the specified operating temperature
environment. (Refer to the Specification chapter for detail)
Gas span check
Gas reading should be verified at regular intervals with a reference instrument or with calibration
gas. The suggested interval for gas span check is once every year.
Pre-use check
Always verify gas readings and waveforms on the patient monitor before connecting the IRMA
airway adapter to the patient circuit .Perform the tightness check of the patient circuit according
to the User Manual for the monitor with the IRMA probe snapped on the IRMA airway adapter.
Perform the tightness check of the patient circuit with the IRMA sensor head snapped on the
IRMA airway adapter.
Verify that there has not been any accumulation of gas between the IRMA sensor head and the
XTP windows by checking that the CO2 readings on the monitor are correct before connecting a
patient to the breathing circuit.
Check that the connections have been made correctly by verifying an actual CO2 waveform on
the monitor display.
Warning
Don’t use the device in the environment which contains flammable
anesthetic gas.
Warning
Before any interpretations are made of parameters readings and waveforms one, assure
that the multi-gas probe is functioning correctly. Partial obstruction of airway with water
