Which component is essential for the delivery of oxygen from a tank to a BMV?

The oxygen regulator is essential for the delivery of oxygen from a tank to a Bag-Mask-Ventilation (BMV) system because its primary function is to control the pressure of the oxygen as it leaves the tank. Oxygen tanks store gas at very high pressures, which can be dangerous if not properly managed. The regulator reduces this high pressure to a safe and usable level, ensuring a consistent and controlled flow of oxygen to the BMV.

In addition to regulating the pressure, the oxygen regulator typically integrates a flow meter, which measures and displays the flow rate of oxygen being delivered. However, the core function of the regulator is to adapt the high-pressure oxygen from the tank to a lower and safer pressure appropriate for medical delivery systems, including a BMV. This makes the regulator a crucial component in the entire oxygen delivery process, allowing for effective and safe oxygen administration during medical emergencies.
