Abstract

A respiration monitor for monitoring respiration of an individual comprising a sending light conductor and a receiving light conductor. The sending light conductor and the receiving light conductor are held in a position generally near a portion of the individual which moves in response to the respiration motion of the individual. More particularly, the ends of the sending light conductor and the receiving light conductor are spaced a distance apart and positioned so that the distance between the end of the sending light conductor and the end of the receiving light conductor varies in response to respiration motion of the individual. A light source emits light which is received by the sending light conductor and transmitted therethrough across the distance between the ends of the sending light conductor and the receiving light conductor, such light being received by the receiving light conductor and transmitted therethrough. The light from the receiving light conductor is received and indications of respiration motion are determined in response to changes in the intensity of the light received from the receiving light conductor and output indications are provided indicative of respiration motion.
