High Humidity Alarm: An immediate, audible alarm at a displayed temperature of 41 °C or if the
airway temperature exceeds 43 °C
Low Humidity Alarm: An audible alarm between 10 minutes @ 29.5 °C, and 60 minutes @ 34.5 °C

Performance
When mounting a humidifier adjacent to a
patient ensure that the humidifier is always
positioned lower than the patient.
Recommended ambient temperature range: 18 - 26 °C
CAUTION: If operating in ambient temperatures outside the recommended range, consult your local
Fisher & Paykel Healthcare representative.

CLEANING MR850 Heaterbase Using a damp cloth, clean the humidifier with either of the following: Isopropyl Alcohol, normal dishwashing detergent. Temperature
Probe Always clean before use. Probes can be cleaned with one of the following solutions: SporicidinTM, CidexTM OPA, SporoxTM OR sterilize the probe using Ethylene Oxide
sterilization at 55 °C (131 °F), 80 kPa, (allow at least 15 hours for residual ETO to disperse before use). Wipe the airway temperature probes clear of any cleaning residues
before use. Store probes in clean conditions. DO NOT autoclave probes.
CAUTION: DO NOT immerse the heaterbase or temperature probe electrical connections in any liquid.
NOTE: Follow the cleaning agent manufacturers’ instructions carefully. It is the user’s responsibility to qualify any deviations from these procedures, both for disinfecting
efficacy and physical effect on the probe and the heaterbase. See the MR850 technical manual for more detailed instructions on cleaning.

SET UP
Slide humidification chamber (a) onto humidifier base and
connect breathing circuit (b) (refer to humidification chamber and
1.
breathing circuit operating instructions for further details).
Connect the temperature probe plug (c) (REF 900MR86X) to the
blue socket on the humidifier base until an audible click is heard.
2.
Push the chamber probe (d) and airway probe (e) into the
breathing circuit. Make sure the chamber probe is correctly
located in its key-way and that both probes are pushed home.
The probe lead can be restrained using breathing circuit clips.

To set the humidifier to non-heater wire mode, refer to the MR850
technical manual. (Rev. H or later).
For all other applications refer to Product Guide or contact your local
Fisher & Paykel Healthcare representative.
If a heated breathing circuit is used while in non-heater wire mode
the humidifier automatically changes to heater wire mode. To use
non-heater wire mode again will require it to be manually set.

Temperature Control Settings (non heated circuits)
Invasive Mode:
Noninvasive Mode: Airway 31 ºC
Airway 37 ºC
The airway probe out test does not work with non-heated breathing
circuits. A low humidity alarm will instead be given.
Alarm Parameters (non heated circuits)
When there is no gas flow the humidifier will give a low humidity
alarm.
High Temperature Alarm: Immediate, audible alarm at a displayed
temperature > 41 ºC
Low Temperature Alarm: Audible alarm at a displayed temperature
< 29 ºC (Invasive), < 26 ºC (Noninvasive)
Performance (non heated circuits)
If the chamber runs dry either a water out alarm or a low humidity
alarm will occur.
Recommended Flow Range: Invasive Mode: 6 to 60 L/min
Non-Invasive Mode: 6 to 120 L/min
