What is a oxygen regulator?

An oxygen regulator is a medical device that controls the flow of oxygen from a pressurized source, such as an oxygen tank, to a patient. It reduces the high pressure of oxygen in the tank to a safe, adjustable level suitable for delivery through a mask or nasal cannula. Regulators often include flow meters to allow healthcare providers to set the desired flow rate for the patient's needs. They are essential in various settings, including hospitals, emergency care, and home oxygen therapy.
