Abstract
A portable instrument which enables a person to measure his pulse rate, vital capacity and/or pulmonary peak flow during exercise comprising a single small, portable case containing all the elements necessary for taking such measurements, i.e., a mouthpiece into which the user exhales, a channel through which the expired air passes, a turbine and a pulse sensor within the channel for detecting respiratory functions and pulse rate respectively, electronic circuitry for converting the measurements into displayable values, an electro-optical display, and batteries.
