Warning:
The IRMA probe is not intended to be in patient contact.
6.3 Pre-use check
Always verify gas readings and waveforms on the monitor before connecting the airway
adapter to the patient circuit.
Perform the tightness check of the patient circuit with the IRMA probe snapped on the
IRMA airway adapter.
6.4 Zeroing procedure
Warning:
Incorrect probe Zeroing will result in false gas readings.
In order to secure high precision of the IRMA probe measurements, the following zeroing
recommendations should be followed.
Zeroing is performed by snapping a new IRMA airway adapter onto the IRMA probe,
without connecting the airway adapter to the patient circuit, and then using the host
instrument to transmit a zero reference command to the IRMA probe.
Special care should be taken to avoid breathing near the airway adapter before or during
