Definition & Meaning of "demand valve oxygen therapy"in English

What is "demand valve oxygen therapy"?

Demand valve oxygen therapy is a technique used to administer oxygen to divers in emergency situations, especially for treating decompression sickness or other diving-related issues. The system uses a demand valve, which releases oxygen only when the diver inhales, ensuring efficient use of the oxygen. This helps restore normal oxygen levels in the body, reducing the effects of nitrogen buildup after a dive. The therapy is commonly used in controlled conditions, such as dive chambers or on-site during emergencies, to provide immediate relief and aid in the diver’s recovery.
