What is the acceptable range for pipeline pressure in psig?

• A. 30-45
• B. 50-55
• C. 60-70
• D. 80-90

Answer: (B)

The acceptable range for pipeline pressure in psig is pertinent for ensuring safe and effective delivery of medical gases within an anesthesia machine. A pressure range between 50-55 psig is considered optimal because it provides sufficient pressure to drive the gas through the system while preventing the risk of excessive pressure that could damage the apparatus or pose a hazard to patients.

This range strikes a balance between ensuring that gas is available at the necessary flow rates for anesthesia purposes without exceeding the pressure limits of the system components, which are typically designed to handle pressures within this range. Deviating from this range can lead to complications such as inadequate gas flow or potential over-pressurization, which might compromise the function of the anesthesia machine or deliver harmful conditions to the patient.
