[The ventilation-perfusion ratio, with special reference to muscular exercise].
The values of VA/Q obtained at rest in 12 normal subjects undergoing cardiac catheterization in a supine position were between 0.63 and 1.695, with a mean of 1.142 +/- 0.295. The VA/Q values obtained in another 10 healthy subjects tested in a sitting position with a rebreathing method for calculating Q. were somewhat less scattered (between 0.77 and 1.50), and also lower (mean 0.975 +/- 0.210). A highly significant correlation was demonstrated during muscular exercise on the bicycle ergometer (sitting position), both between oxygen consumption and alveolar ventilation and between oxygen consumption and cardiac output. However, since at various submaximal work loads cardiac output increased much less than alveolar ventilation, the overall VA/Q ratio showed a progressive increment with increasing oxygen consumption.
