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: Sporicidin
TM
, Cidex
TM
OPA, Sporox
TM
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.
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.
