We see a similar distribution of blood flow in the lung as well, as figure 9.7 shows with blood flow being greater at the base of the lung than it is at the apex. Again this is simply due to gravity. Gravity pushes against the blood rising from heart level, hence … WebNov 3, 2001 · Pulmonary vascular resistance (PVR) is the slope of the (Ppa-Pla)/Q relation. Passive increases in flow (A to B and C to D) increase pressure less than predicted by the PVR equation. Exercise (A to C and B to D) increases pressure more than predicted by the PVR equation.

WebMar 6, 2024 · Pulse volume recording (PVR): A form of plethysmography used to measure arterial flow qualitatively indirectly. To obtain a PVR, a cuff is inflated to about 65mmHg and then attached to a plethysmograph. With each pulse, the blood volume affects the pressure of the cuff, which is then recorded as an arterial contour.
