Über die Bestimmung des Minutenvolumens

The effect of exercise on the volume of the blood

“…In man, Chang and Harrop (8), employing the carbon monoxide method for the blood volume, exercised 4 normal individuals on a bicycle ergometer for from 6 to 10 minutes and found that the total circulating blood volume was increased from 1.3 to 7.3 per cent. Ewig and Hinsberg (9) and Wollheim (10) using the dye method found an average increase of 11.8 per cent in the plasma volume and 15.1 per cent in the cell volume after short periods of moderate exertion in normal subjects. Levin (11) determined the plasma volume immediately after exercise in 11 subjects and found it decreased in 8 subjects, unchanged in 1 and increased in 2, while the cell volume was diminished in 4, increased in 4 and unchanged in 3 cases.…”

Carbon Dioxide and Oxygen Tensions of the Mixed Venous Blood of Man at Rest

“…In recent months, Ewig and Hinsberg (14) have described a method, similar to that of Douglas and Haldane, except that they purposely employ mixtures which give final values on either side of the equilibrium, and calculate the oxygenated venous tension by interpolation.…”
