What is the standard gauge pressure range for most station outlets?

• A. 60-70 psi
• B. 40-45 psi
• C. 55-60 psi
• D. 50-55 psi

Answer: (D)

Hospital medical gas systems keep the pressure at station outlets around a standard value so that regulators and devices downstream receive a consistent feed. The typical gauge pressure is about 50 psi, with a small tolerance to account for flow changes and regulator performance. Using roughly 50–55 psi at the outlets provides enough pressure to push gas through regulators and flow meters while staying within safe, compatible limits for the equipment. Pressures much higher, like 60–70 psi, would risk over-pressuring devices and increase hazards, while too-low pressures, such as 40–45 psi, could lead to uneven flow or regulator dropout. So the standard range for most station outlets is 50–55 psi.
