How is the anaesthetic machine checked?
Check the machine for leaks by covering the common gas outlet with your thumb. DO NOT maintain the pressure for long (as this may cause damage). The oxygen flow will drop from 4L/min and there should be an audible hiss from the high pressure relief valve.
How do you check a scavenging anesthesia machine?
If the scavenging collection bag becomes too distended, the positive-pressure relief valve will open and allow WAG to escape into the room. If suction/vacuum on the scavenging interface is set too high, then there is potential for the active scavenging system to pull fresh gas away from the patient.
Why is it important to check the anaesthetic machine?
The purpose of this detailed check is to ensure the machine is safe to use. The careful attention to the check is a reflection of good practice which the practitioner’s codes of professional practice demand (HPC 2004, NMC 2004).
How often should anesthesia machines be checked?

How do you maintain an anesthesia machine?
SERVICE. Care and maintenance involves daily, weekly, and/or monthly procedures performed to keep the machine in optimum working condition. This includes changing the soda sorb, filling the vaporizer, removing moisture, and cleaning the machine.
