Quick question for the CRNA brain: in the U.S., what color is the oxygen pipeline and what pressures should you expect from the wall supply and a full E-cylinder? I quiz my SRNAs on this during the 0600 machine check because it’s foundational to ASA equipment standards and catching pipeline failures before induction.
Green for O2 in the U.S.; wall pipeline runs about 50 psi, and a full E-cylinder reads around 2000 psi. > quiz my SRNAs on this during the 0600 machine check because it’s foundational — agree; I crack the backup tank to confirm >1800 psi, then leave it off so a pipeline fail won’t silently drain it. , ISO uses white for O2, so I warn SRNAs not to get fooled by a white cap on imported gear — do you also run a pipeline disconnect drill then?
During the 0600 machine check I do a quick pipeline-failure drill — pop off the green O2 hose, watch the gauge drop from about 50 psi, confirm the E-cylinder takes over (about 2000 psi when full), then shut the tank so it doesn’t quietly bleed down. Minor caveat: if you travel, O2 piping is white in many countries; APSF’s overview is solid: https://www.apsf.org/article/anesthesia-gas-supply-failure-prevention-and-management/. You run that drill daily?
I add a quick ‘disconnect line, crack cylinder, then close’ at 0600, @canderson59 — confirm PISS/DISS; paint can mislead.
