What pressure reading indicates a full oxygen tank?

A full oxygen tank typically shows a pressure reading of around 2000 psi. This value is based on standard tank specifications, where a full medical oxygen cylinder, especially those used in dental settings, is calibrated to hold gas at high pressure.

Knowing this is crucial for safety and effective patient management, as an inadequate pressure reading could indicate an empty tank or one that may need refilling soon. Understanding the correct pressure also ensures that adequate oxygen is available for sedation or emergency situations. The options of 1000 psi, 1500 psi, and 2500 psi either represent partial fills or potential over-pressures, which do not align with the standard definition of a full oxygen cylinder.
