Abstract

A gas regulation system is provided comprising a source of a breathable gas, a tube in communication with the source for delivering the breathable gas from the source to an individual, and a valve for controlling the rate of gas flow from the source to the individual for inhalation. A remote control unit for controlling the valve is also provided to allow the individual to adjust the rate of gas flow from the source through the tube to the individual independently from any inhalation activity by the individual. Typically, the system excludes any means for automatically adjusting the rate of gas flow from the source through the tube to the individual according to the level of physical activity of the individual. The invention is particularly useful when the valve is out of the individual'"'"'s reach. Also provided is a method for delivering of a breathable gas to an individual.
