WARNING
Ensure that invasive mode is set for patients that have bypassed airways.
The use of breathing circuits, chambers or other accessories which are not approved by Fisher & Paykel Healthcare may impair performance or compromise safety.
Ensure that both temperature probe sensors are correctly and securely fitted. Failure to do so may result in temperatures in excess of 41 °C being delivered to the patient.
Ensure maintenance of grounding integrity by connection to a "hospital grade" receptacle. Always disconnect supply before servicing.
When mounting a humidifier adjacent to a patient ensure that the humidifier is always positioned lower than the patient.
The operation of high frequency surgical apparatus, shortwave or microwave equipment in the vicinity of the humidifier may adversely affect its function. If this occurs, the humidifier should be removed from the vicinity of such devices.
Do not touch the glass tip of the chamber temperature probe during use. Keep black connectors dry at all times.
Visually inspect accessories for damage before use.
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.
