ABSTRACT:
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.
