Effects of increased and decreased tissue pressure on haemodynamic and capillary events in cat skeletal muscle.

Abstract: 1. The controversial problem concerning the unusual haemodynamics of the deranged circulation during increased hydrostatic tissue pressure (PT) was elucidated by detailed studies of arterial, capillary and venous functions in cat skeletal muscle exposed to graded experimental changes of PT over a wide range. 2. The results indicated that the impaired circulatory state in skeletal muscle during raised tissue pressure is characterized by the following train of events: (a) a primary partial passive compression of… Show more

“…Application of the high vacuum anchored the liner to the socket, causing a 27% increase in negative pressure on the limb during the swing phase and a 7% decrease in positive pressure during the stance phase (Beil et al, 2002). Both of these pressure changes, but principally the increase in negative pressure, are thought to be responsible for shifting the fluid balance to a net gain (Guyton and Hall, 2000;Mellander and Albert, 1994). In the current study, in the sitting condition where the limb was not exposed to the negative pressure of swing phase, the fluid shift reverted back toward a net loss.…”

“…Negative pressure or suction externally applied to skin has been shown to increase the amount of fluid drawn into soft tissues [32]. Both modes of suspension apply high suction to the distal end of the residual limb during swing phase.…”

“…Increased interstitial fluid pressure, if not mirrored by increases in blood pressure, will lead to decreased transmural pressure (lumenal pressure minus interstitial pressure) across vascular walls, thereby lowering vascular diameter and hindering perfusion [18]. In particular, transmural pressure must remain above a certain threshold (the so-called “closing pressure”) to avoid vascular collapse [1921]. Published values of closing pressures range from −5 to 25 cm H 2 O [2023]; in general, the greater the vascular tone, the greater the threshold value [22, 23].…”
