19.3.4.1 Placement of IRMA Probe
When connecting IRMA probe to an infant patient circuit, it is important to avoid a direct contact
between the IRMA probe and the infant's body. If, for whatever the reason, the IRMA probe is in
direct contact with any parts of the infant's body, an insulation material shall be placed between
the IRMA probe and the body.
The IRMA probe is not intended to be in long term skin contact.
19.3.4.2 Performing a Pre-use Check
Prior to connecting the IRMA airway adapter to the breathing circuit, 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.
19.3.4.3 Zeroing
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 the
zeroing procedure. The presence of ambient air (21% O
adapter is of crucial importance for a successful zeroing. If a " Zero Required " appears directly
after a zeroing procedure, the procedure has to be repeated.
Always perform a pre-use check after zeroing the probe.
