Why the study?
Do postural changes (lowering the calf) affect fluid filtration rate and blood flow in healthy subjects?
Do postural changes (lowering the calf) affect fluid filtration rate and blood flow in healthy subjects?
Lowering the calf induces a local veno-arteriolar reflex that causes vasoconstriction and reduces transcapillary fluid filtration, likely by limiting the increase in mean capillary pressure.
No takes yet. Share an insight, caveat, or question.
Supports veno-arteriolar reflex in healthy limbs; leaves open relevance for edema or venous disease.
Sejrsen et al. (1981) studied this question.
