Monitoring Anesthetic and Respiratory Gases
Efficia CM Series Rack and Modules Instructions for Use 6-7
Removing Exhaust Gases
The Anesthetic and Respiratory Gas module is a diverting respiratory gas monitor /
sidestream monitor, that transports a portion of respiratory gases from the sampling site
through the sampling tube (sample line) to the sensor, which is remote from the sampling
site.
The diverted sample gas leaving the module through its gas exhaust must be treated
properly. Two solutions are possible:
1. Wasting the diverted sample gas to a scavenging system. A hose is connected to the
gas exhaust of the module. The other side of the hose is then inserted into a gas
scavenging system (e.g. waste anesthetic gas disposal outlet or vacuum outlet).
2. Returning the sample gas to the breathing system of the anesthesia machine
(especially desired for low-flow and minimal-flow anesthesia applications). A sample
gas return set is connected between the gas exhaust of the module and the
anesthesia machine before the CO
2
absorber. The sample gas return set must
incorporate a microbial filter.
The hoses connected to the gas exhaust of the Anesthetic and Respiratory Gas module
shall not generate significant pneumatic resistance, otherwise the pump of the module
may fail.
Warnings • Place the Gas module at least 25 cm (10 inches) away from any ignition sources, such
as electrosurgery and laser surgery.
• Do not use the monitor or modules in areas where oxygen concentrations exceed
25%, or where combustible or explosive gas mixtures are likely to occur.
• Do not use the monitor or modules if oxygen leakage is suspected in the medical
device or in its vicinity.
