Initial operation of the IRMA sensor
4.10.4
Placement of IRMA sensor
When connecting the IRMA sensor to an infant patient circuit, it is important to
avoid the direct contact between the IRMA sensor and the infant’s body. Use
insulation material between the body and the IRMA sensor to avoid contact.
• The sensor requires a warm-up time of around ten seconds to provide fully
accurate measurements.
• A correction related to O2 usage is available in the menu setting
EtCO2>Type of
ventilation
. If patient is ventilated with Air and O2, set
Type of ventilation
to =
“Air +
O2
” if ventilated only with air set it to “
Air
”.
1. Connect the sensor cable to the main cable
(1)
. Snap the sensor head on top of
the airway adapter. Make sure it clicks into place.
2. A green LED indicates that the sensor is ready for use.
3. Select the EtCO2 measurement
field
(2)
to open the EtCO2 menu. “
4. Select OFF/ON button
(3)
to start the measurement.
5. Check if the etCO
2
value is zero.
6. If needed, carry out a zeroing (see page
).
7. Connect the narrower end of the airway adapter to the breathing circuit Y-piece.
8. Connect the end of the airway adapter to the patient’s endotracheal tube.
9. Check the CO
2
curve on the display to see if the connections have been made
correctly and the CO
2
value is in the expected range. The curve rises during ex-
piration.
The IRMA probe is not intended to be in patient contact.
