What is the oxygen capacity of an M cylinder?

The oxygen capacity of an M cylinder is indeed 3,000 liters. This measurement refers to the amount of gaseous oxygen that can be stored inside the cylinder when it is filled to its maximum capacity, typically at a pressure of around 2,000 psi. Understanding this capacity is crucial for medical personnel, especially Hospital Corpsmen, since it directly impacts treatment protocols and emergency preparedness.

Knowing the capacity informs the decision on how long the oxygen supply will last depending on the flow rate being utilized during treatment. For instance, if a patient requires oxygen therapy at a certain flow rate, this information helps in calculating how long the oxygen will be sufficient for that patient's needs. This understanding is foundational for ensuring adequate respiratory support in various medical situations.
