Valves, Demand, Oxygen

Definition : Demand valves used in medical gas systems to control the flow of oxygen according to the patient's demand, or need, for the oxygen. The oxygen flow is controlled by the patient's respiratory effort; the deeper the inhalation, the greater the demand for the oxygen and the greater the flow. During inspiration, a negative pressure is applied that opens the demand valve, thereby increasing flow of the oxygen. During exhalation, a positive pressure is applied that closes the demand valve and shuts off the oxygen supply. Oxygen demand valves are used in hospitals and most other healthcare facilities with patients who need assisted breathing. They can be hand-held, used with portable medical gas cylinders, or with a central gas supply line.
