Studies on Respiratory Movements

Continuous Respiration without Respiratory Movements

The object of the function of respiration is to supply the animal with oxygen and to remove carbon dioxide. To attain this object the vertebrates are provided with a complicated mechanism of which the respiratory movements are an essential feature. The respiration appears as a continuous chain of rhythmically recurring cycles, each cycle consisting of two antagonistic movements, one which carri...

Observations on the Nervous Control of Respiratory Movements.

A Study of Types of Respiratory Movements

1. Children of the two sexes differ very little in the character of their respiratory movements. 2. Between girls and women and boys and men there is little or no difference in respiratory type. 3. Childbearing does not permanently affect respiration. 4. The natural type of respiration, for both sexes is one in which the movement is fairly equally balanced between chest and abdomen, the abdomin...

Electrodiagnostic Respiratory Studies

Studies of Respiratory Physiology

Studies of lung diffusing capacity for carbon monoxide (DLCO) at various alveolar 02 tensions (1, 2) and on the kinetics of the carboxyhemoglobin reaction (3, 4) have made possible the calculation of the diffusing capacity of the pulmonary membrane (DM) and the pulmonary capillary blood volume (V,) (5). In the present study DLCO, DM and V, have been determined in 34 patients with various types ...
