Gas Standby Mode
The Gas Menu provides an option to turn the Gas module On or to put it on Standby.
When the module is on Standby, the pump is turned off, however the fan remains on and
keeps the components warm, thus when you exit standby mode, the measurement is
available almost instantly.
When the Efficia monitor is put in suspended mode, the Gas module is put in standby
mode automatically, and when the monitor leaves suspended mode, the Gas module
returns to operating mode.
The low priority, visual-only alarm, “Gas Alarms Suppressed” will be displayed when the
Gas module is turned on or leaves standby mode. The alarm means that the Gas
module’s physiological alarms (high/low and apnea) are suppressed until breathing
activity is detected. To confirm breathing activity, the monitor waits until 4 breath cycles
are detected. This is to prevent alarms before the patient is actually connected to the
monitor.

Note — The Gas measurement module and its accessories are not made with natural rubber latex.
Measurement Troubleshooting
Numerous factors can influence the accuracy of the Gas measurement output values:
sampling tube erroneously connected, sample flow reversed, kinked sampling tube, etc.
Problems that can occur:
• No gas measurement data
• Small amount of blood extracted from the patient.
Follow your institution’s policies and protocols for performing Gas measurements.
Warning Philips recommends cleaning and disinfecting the monitor and module before
maintenance is performed, or if the equipment is returned for repair. Turn the monitor off
before you begin cleaning and disinfecting.
