What is the typical output pressure from a regulator valve on an oxygen cylinder?

• A. 15 psi
• B. 30 psi
• C. 45 psi
• D. 60 psi

Answer: (C)

The typical output pressure from a regulator valve on an oxygen cylinder is around 45 psi. Regulators are designed to reduce the high pressure from the cylinder to a much lower and more manageable level that is safe for patient delivery systems.

At approximately 45 psi, the oxygen can be effectively delivered to the anesthesia machine or directly to the patient. This output pressure aligns with the safe operational levels for medical gases, allowing for adequate flow rates without the risks associated with high-pressure gas delivery. Keeping the output pressure at this level is crucial for ensuring that the gas can be properly utilized and administered.

While other values may represent other setups or types of equipment, 45 psi is widely recognized as a standard output pressure for the purpose of oxygen delivery in clinical settings.
