What is the typical pressure for oxygen supplied in medical settings?

In medical settings, the typical pressure for oxygen supply is standardized at around 50 psig (pounds per square inch gauge). This pressure is established to ensure that oxygen can be delivered safely and effectively to patients through medical gas systems.

The 50 psig setting appropriately balances the need for a strong, consistent flow of oxygen necessary for various medical applications while remaining within safety limits to prevent hazards such as over-pressurization of equipment. Moreover, this pressure aligns with industry standards and the requirements set forth by organizations governing medical gas installations, ensuring compatibility with regulators, hoses, and delivery devices.

Other pressure levels like 30 psig, 70 psig, and 90 psig are not commonly utilized for medical oxygen. They do not provide the optimal balance of safety and performance required in clinical environments, either being too low to ensure an adequate supply or too high, which could lead to risks in handling and administering the oxygen. As such, the 50 psig pressure setting is recognized as the best practice in the medical community for oxygen supply.
