  • Page 33: System Assembly Instruction

    3 CO Module 3.3 System Assembly Instruction 3.3.1 Set-up 1. Plug the IRMA connector into the CO module connector on Ventilator rear panel and switch the power on. 2. Snap the IRMA probe on top of the IRMA airway adapter. It will click into place when properly seated.
  • Page 34 5. Connect the IRMA/airway adapter 15 mm female connector to the patient’s endotracheal tube. Alternatively, connect a HME (Heat Moisture Exchanger) between the patient’s endotracheal tube and the IRMA probe. Placing a 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.

  • Page 35: Placement Of Irma Probe

    3 CO Module 3.3.2 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.

  • Page 36: Alarms

    Always wait at least 10 seconds after changing the IRMA adapter before running the Pre-use test to allow the CO sensor to warm up. Zeroing needs to be performed only when an offset in gas values is observed, or when an unspecified accuracy message is displayed.
  • Page 37 3 CO Module WARNING: Used airway adapters shall be disposed of in accordance with local regulations for medical waste. WARNING: Do not use the IRMA Adult/Pediatric airway adapter with infants as the adapter adds 6 mL dead space to the patient circuit WARNING: Do not use the IRMA Infant airway adapter with adults as this may cause excessive flow resistance.

  • Page 38: Cautions

    WARNING: The IRMA probe is intended only as an adjunct in patient assessment. It must be used in conjunction with other assessments of clinical signs and symptoms. WARNING: Incorrect probe zeroing will result in false gas readings. WARNING: Replace the adapter if rainout/condensation occurs inside the airway adapter WARNING: Use only PHASEIN manufactured IRMA airway adapters.
