title: A combined sensor suitable for telemetering respiratory functions.
abstract: A system for measuring oxygen consumption from momentary respiratory values of free moving person is described. The main part presented here is a sensor consisting of a flowmeter based on the impeller principle, called 'Wirbelrespirometer', joint with a polarographic electrode sensitive to oxygen, and a very fast reacting thermistor. First comparative studies in computation of respiratory volume and oxygen consumption yielded average deviations against comparison methods of less than +/- 1% for computation of volume, and +/- 4% for computation of oxygen consumption.
