title: Effect of occlusion duration on reactive hyperemia in sartorius muscle capillaries.
abstract: Reactive hyperemia was studied in cat sartorius muscle by measurement of venous outflow and capillary red cell velocity following occlusions of 5-120 s. The peak value for volume flow rose in a graded manner as occlusion duration increased, reaching a level of 280% above control following 120 s of occlusion. By contrast, peak values for capillary flow were 200% above control even after short (10-15 s) occlusions and increased moderately thereafter to 280% above control following 120-s occlusions.
