What is the typical pressure of the hospital oxygen pipeline in a anesthesia system?

• A. 20-25 psi
• B. 50-55 psi
• C. 100 psi
• D. 200 psi

Answer: (B)

Gas pipeline systems in hospitals are designed to deliver oxygen at a steady, moderate pressure to support multiple outlets and devices. The standard wall oxygen supply is maintained around 50 psi, with typical variation up to the mid-50s as needed. This pressure is high enough to push gas through the distribution network and regulators but low enough to be safe and manageable within the building systems. Within the anesthesia machine, this line pressure is reduced by a regulator to the lower, precise working pressures needed for flowmeters and the breathing circuit. In contrast, cylinder oxygen sits at much higher pressures (around 2,000 psi), which is why the pipeline and cylinder sources are not interchangeable. Therefore, the typical pressure of the hospital oxygen pipeline is about 50 psi (often cited as 50-55 psi).
