10.10.5 Alarms
Include a description of the host alarm system, including the gas reading alarm limit range, its
discrimination, and the implementation of alarm and status information transmitted by the IRMA probe.
Include a description of the status LED situated on the IRMA probe:
Steady green light System OK
Blinking green light (IRMA AX+) Zeroing in progress
Steady blue light Anesthetic agent present
Steady red light Sensor error
Blinking red light Check adapter
10.10.6 Cleaning
The IRMA probe can be cleaned using a cloth moistened with ethanol or isopropyl alcohol.
CAUTION: The IRMA oxygen sensor cell and IRMA airway adapters are non-sterile devices. Do
not autoclave the devices as this will damage them.
CAUTION: Never sterilize or immerse the IRMA probe in liquid.
10.10.7 Preventive Maintenance Instructions
Gas span check:
Gas readings should be verified at regular intervals with a reference instrument.
Replace the IRMA airway adapter every two months.
10.10.8 Warnings
The IRMA probe is intended for use by authorized and trained medical personnel only.
The IRMA probe must not be used with flammable anesthetic agents.
Disposable IRMA airway adapters shall not be reused. Used disposable airway adapter shall be
disposed of in accordance with local regulations for medical waste.
Do not use the IRMA Adult/Pediatric airway adapter with infants as the adapter adds 6ml dead space
to the patient circuit.
Do not use the IRMA Infant/Pediatric airway adapter with adults as this may cause excessive flow
resistance.
Measurements can be affected by mobile and RF communications equipment. The IRMA probe
should be used in the electromagnetic environment specified in this manual.
Do not place the IRMA airway adapter between the endotracheal tube and an elbow as this may
allow patient secretions to block the adapter windows and result in incorrect operation.
To keep secretions and moisture from pooling on the windows or oxygen sensor port,a lways position
the IRMA probe in a vertical position with the LED pointing upwards.
Do not use the IRMA airway adapter with metered dose inhalers or nebulized medications as this
may affect the light transmission of the airway adapter windows.
Incorrect probe zeroing will result in false gas readings.
Replace the adapter if condensation occurs inside the airway adapter.
The IRMA probe is not intended to be in long term contact with skin.
10.10.9 Cautions
Never sterilize or immerse the IRMA probe in liquid.
Do not apply tension to the probe cable.
Do not operate the IRMA probe outside the specified operating temperature environment.
