DEVELOPMENT AND APPLICATION OF A CONTINUOUS OXYGEN UPTAKE MEASUREMENT SYSTEM.
Abstract
A system is described which continuously monitors parameters in expiratory gases which are needed to calculate oxygen uptake in humans: oxygen concentration; carbon dioxide concentration; total accumulated ventilation; expired gas temperature; and barometric pressure. Other physiologically related parameters are also monitored: pulse rate; respiration rate; environmental relative humidity; environmental temperature; and body temperature. These parameters are recorded in a near continuous manner on a multipoint type analog strip chart recorder, with the system connected to a human subject under conditions of rest or moderate to heavy exercise. This system also has the capability of measuring the oxygen and carbon dioxide concentration of gases which have been collected in external containers such as gasometers and Douglas bags. The reliability of the continuous system, as compared to other conventional methods, is discussed. (Author)
