What is the cylinder constant for an H tank?

The cylinder constant for an H tank is 3.14. This value is crucial for calculating the duration of oxygen supply from a cylinder in various clinical scenarios, including emergencies where oxygen delivery is necessary.

The cylinder constant is derived from the physical characteristics of the tank, including its volume and the pressure at which it is filled. A standard H tank holds 244 cubic feet of oxygen at a full pressure of approximately 2200 psi. The cylinder constant helps paramedics estimate how long the oxygen will last at a given flow rate, simplifying the process during critical care situations.

Understanding the cylinder constant is essential for effective patient management, as accurate calculations allow for better planning during transport or when there is a need for supplemental oxygen administration.
