An M tank, commonly used in emergency medical services for oxygen delivery, has a capacity of 3,000 liters of oxygen when it is filled to standard pressure. This specific capacity is critical for EMTs to understand, as it informs how long the oxygen supply will last during a medical emergency and affects decisions regarding patient treatment and transport.

Oxygen tanks are classified by their size and the amount of oxygen they contain, with different tanks serving different purposes according to the needs of the situation. Knowing the specific volume of an M tank helps EMTs and paramedics ensure they are adequately prepared when responding to calls, as oxygen is often a vital component in treating patients with respiratory distress or other conditions requiring supplemental oxygen.
