How many liters of oxygen are stored in a D cylinder?

A D cylinder typically contains approximately 350 liters of oxygen when it is fully pressurized. This size of cylinder is commonly used in various emergency medical settings due to its portability and ease of use. The volume of gas that a cylinder can contain is determined by its size and the pressure rating, which is standardized for most medical oxygen cylinders.

Understanding the capacity of different oxygen cylinders is crucial for paramedics and emergency responders as it influences how long the oxygen supply will last during treatment or transport of patients. It's important to recognize that while there are several sizes of oxygen cylinders with distinct volumes, the D cylinder's capacity is a fundamental detail that supports effective emergency care planning.
