Which part of a medical oxygen delivery system controls the flow of oxygen when the valve is activated?

The regulator is a crucial component of a medical oxygen delivery system, as it is responsible for controlling the flow of oxygen from the oxygen cylinder when the valve is activated. When oxygen is stored in a cylinder, it is under high pressure. The regulator reduces this pressure to a safer, more manageable level suitable for delivery to the patient.

The flow meter, while related to the regulation of oxygen, specifically measures and indicates the flow rate of oxygen being delivered to the patient, typically in liters per minute. The compressor is not part of a standard oxygen delivery system; it is usually associated with systems that require mechanical assistance to generate airflow. The oxygen cylinder is the storage container for the oxygen itself but does not control the flow.

In summary, the regulator is essential for ensuring that the patient receives the correct amount of oxygen at a safe pressure, making it the vital component that controls the flow of oxygen during use.
