Perform zeroing (see section 4) if gas readings does
not show 0% or if an unspecified accuracy message is
displayed
IV. A green LED indicates that the IRMA probe is ready for use.
V. Connect IRMA/airway adapter 15 mm male connector to the breathing circuit Y-

VI. Connect the IRMA/airway adapter 15 mm female connector to the patient’s
endotracheal tube.
Alternatively, connect an HME (Heat Moisture Exchanger) between the
patient’s endotracheal tube and the IRMA probe. Placing an HME in front of
the IRMA probe protects the airway adapter from secretions and effects of
water vapor and eliminates the need of changing the adapter. It allows free
positioning of the IRMA probe as well.
VII. Unless the IRMA probe is protected with an HME always position the IRMA
probe with the status LED pointing upwards.
