Microvascular oxygen partial pressure during hyperbaric oxygen in diabetic rat skeletal muscle.
Hyperbaric oxygen (HBO) is a major therapeutic treatment for ischemic ulcerations that perforate skin and underlying muscle in diabetic patients. These lesions do not heal effectively, in part, because of the hypoxic microvascular O2 partial pressures (PmvO2 ) resulting from diabetes-induced cardiovascular dysfunction, which alters the dynamic balance between O2 delivery (Q̇o2) and utilization (...
متن کاملImpaired skeletal muscle microvascular function and increased skeletal muscle oxygen consumption in severe falciparum malaria.
BACKGROUND Organ dysfunction and tissue hypoxia in severe falciparum malaria result from an imbalance between oxygen delivery and demand. In severe malaria, microvascular obstruction from parasite sequestration decreases oxygen delivery. However, host microvascular function (defined as the capacity to increase oxygen delivery in response to ischemia) and oxygen consumption have not been assesse...

STAINSBY, WENDELL N., AND ARTHUR B. OTIS. BZoodLfTow, blood oxygen tension, oxygen uptake, and oxygen transport in skeletal muscle. Am. J. Physiol. 206(4) : 858-866. rg64.-The effect of changes in blood flow and of blood oxygen tension on oxygen uptake of the in situ gastrocnemius-plantaris muscle group of the dog was examined. Oxygen uptake by resting muscle was not altered by changes in blood...
متن کاملA theoretical model for oxygen transport in skeletal muscle under conditions of high oxygen demand.
Oxygen transport from capillaries to exercising skeletal muscle is studied by use of a Krogh-type cylinder model. The goal is to predict oxygen consumption under conditions of high demand, on the basis of a consideration of transport processes occurring at the microvascular level. Effects of the decline in oxygen content of blood flowing along capillaries, intravascular resistance to oxygen dif...
متن کاملMicrovascular oxygen tension in the rat mesentery.
Longitudinal Po(2) profiles in the microvasculature of the rat mesentery were studied using a novel phosphorescence quenching microscopy technique that minimizes the accumulated photoconsumption of oxygen by the method. Intravascular oxygen tension (Po(2), in mmHg) and vessel diameter (d, in microm) were measured in mesenteric microvessels (n = 204) of seven anesthetized rats (275 g). The excit...
