Popis: The reactivity of the pulmonary capillary bed during exercise as estimated by change in the pulmonary diffusing capacity (D l co ) has been shown to be dependent upon at least two separate mechanisms. The initial (0 to 10 second) D l co rise with exercise appears to be volume-pressure dependent and may be altered by mechanisms influencing these factors in the lungs. The later elevation of D l co with exercise was demonstrated to be primarily independent of the initial rise and uninfluenced by factors affecting peripheral venous return, that is body position and ganglionic blockade.
