Measurement of Oxygen Uptake with a New Method
Since March 1979 we have performed 3000 pulmonary function testings in the Department of Anesthesiology, University of Mainz Medical School, using the Hewlett Packard Pulmonary Calculator System HP 47804S. This computer-supported system includes three pneumotachographs in combination with gas analyzers for nitrogen, carbon monoxide, and helium (Fig. 1) (Voigt et al. 1975). The device measures forced expiratory flow patterns, static lung volumes (by open spirometry or nitrogen washout), ventilatory disturbances, and carbon monoxide diffusing capacity.
