What is the approximate pressure in a full oxygen cylinder?

• A. 2,000 psi
• B. 3,000 psi
• C. 1,000 psi
• D. 500 psi

Answer: (A)

Oxygen is stored in cylinders under high pressure, and the gauge on the regulator shows how much is left. In typical EMS practice, a full oxygen cylinder is filled to about 2,000 psi. That pressure is used as a practical benchmark to estimate remaining gas, knowing that as you deliver oxygen the pressure drops. If you see much higher pressure (for example, around 3,000 psi) that could correspond to a different, larger cylinder type, but for the standard EMS full cylinder the common approximation is 2,000 psi. Lower readings like 1,000 psi or 500 psi reflect a partially used or nearly empty cylinder. So the best approximate value for a full cylinder in this context is about 2,000 psi.
