Monitoring Anesthetic and Respiratory Gases
6-16 Efficia CM Series Rack and Modules Instructions for Use
Maintenance
The biomed at your hospital should be perform regular inspection and service of the
monitor and gas module. Philips recommends that for repairs and complex maintenance,
these should be performed by experts and/or the manufacturer.
Authentic parts should be used for all repairs. Refer to the Service and Repair Guide for
the Rack and Modules and also the Installation and Configuration Guide.
Gas Measurement Safety Information
The Gas module is suitable in the presence of electrosurgery.
Warnings Risk of performance degradation:
• The monitor and its accessories must be tested by qualified service personnel at
regular intervals to ensure that performance has not been degraded by aging or
environmental conditions. Periodic performance verification tests can be performed,
as described in the Efficia CM Service Guide.
• Measurement accuracy may decrease temporarily while performing electro-surgery or
defibrillation. The recovery time is less than 10 seconds. This does not affect patient or
equipment safety.
Risk of injury or health hazard:
• Explosion Hazard. Equipment not suitable for use in the presence of a flammable
anaesthetic mixture with air or oxygen or nitrous oxide. Oxygen concentrations must
be <25% and partial pressure <27.5 kPa when no other oxidants are present.
• Do not use the Gas measurement module in flammable environments i.e.: anesthetic
mixture with air, with oxygen or nitrous oxides. Do not use in the presence of
explosive anesthetic agents such as alcohol, ether, cyclopropane or spray them into
the device.
• To avoid injury, place the medical device on a secure and level platform. Do not place
the rack module, cables, hoses and/or sample line on the ground.
Do not place anything
on top of the medical device.
• The sample gas must not be wasted to the ambient air. Contamination of the ambient
air with sample gas causes a health hazard to the personnel in the operating room
and leads to inaccurate measurement values when used for zeroing purposes.
• During a cardiopulmonary bypass, disconnect the sample line and seal the Luer Lock
connector on the Y-piece or switch the gas analyzer to standby mode.
• To prevent or minimize burns caused by a defective neutral electrode connection, use
caution when handling electrodes, transducers, and cables in the presence of high-
frequency surgical equipment. Verify that the equipment is working correctly before
each use.
• Do not operate the Gas measurement module without the water trap. Always use the
water trap to avoid cross-infection of patients, exposing patient to contaminated
breathing gas, and damages to the gas measurement module. Contaminated liquid in
the water trap could be exposed to the user while draining the removable water trap
or touching the water trap or device surface.
