6.1.3 Bleed Gas Pressure
Make sure to bleed the gas pressure inside the anesthesia machine before disassembling
pneumatic fittings to avoid personal injury or equipment damage. To bleed gas pressure:
1. Close other cylinder valves and disconnect pipeline gas supplies. Do not disconnect
the O2 pipeline. If O2 pipeline is not available, connect O2 cylinder and open the O2
cylinder valve.
2. Set the system switch to ON.
3. Turn on all the flow controls (except O2).
4. Make sure that N2O and AIR pipeline pressure gauges read zero.
5. Disconnect the O2 pipeline supply (or close the O2 cylinder valve). Push the O2 flush
button to bleed O2 from the system.
6. Set the system switch to OFF.
