What is the minimum capacity for a portable oxygen cylinder?

The minimum capacity for a portable oxygen cylinder is typically set at 500 liters. This capacity ensures that the cylinder can supply an adequate amount of oxygen, especially in emergency situations where patients might require supplemental oxygen for extended periods.

Portable oxygen cylinders are designed to provide sufficient oxygen flow for various situations, particularly for patients with conditions like respiratory distress, where maintaining adequate oxygen saturation is critical. A cylinder with a capacity of 500 liters can deliver oxygen effectively without needing frequent changes or refills during transport or treatment.

While smaller cylinders exist for specific uses, they generally do not meet the minimum standard for portable oxygen in emergency medical contexts, making the 500-liter capacity the established baseline for such equipment.
