An apparatus which minimizes the amount of oxygen needed to maintain a specific oxygen level in the blood of an individual can be constructed so as to use a transducer and other circuit components to obtain a first series of pulses or signals corresponding to the individual\s breathing. A divider or counter processes the signals or pulses of the first series to create a second series of pulses or signals corresponding to periodic pulses or signals of the first series. The pulses or signals of the second series are used to periodically open a valve to deliver oxygen to the individual at about the start of the person\s periodic breathing cycles.

A process of delivering a gas to an entrance into the pulmonary tract of a patient during breathing in which the gas is placed in a location where it will be inhaled during the inhalation part of the breathing cycle in which the improvement comprises: obtaining a series of repetitive electric signal

A process of delivering a gas to an entrance into the pulmonary tract of a patient during breathing in which the gas is placed in a location where it will be inhaled during the inhalation part of the breathing cycle in which the improvement comprises: obtaining a series of repetitive electric signals of varying amplitude from a series of uniform repetitive pulses, said signals of varying amplitude corresponding to the breathing rate of the patient, said series of signals of varying amplitude being obtained by using a variable capacitor transducer means capable of being activated by the spontaneous breathing of the patient where it can be so activated and using the spontaneous breathing of the patient to so activate said transducer means, the variations between said signals of varying amplitudes corresponding to various inhalation/exhalation intervals during the breathing cycle, selecting periodic signals of said series of signals of varying amplitude corresponding to inhalation intervals so as to create another series of signals, and using said signals of said other series to cause release of said gas at about the start of said inhalation portion of said breathing cycle to said location so that said released gas will be inhaled at about the start of said inhalation part of said breathing cycle.
