The distribution of cardiac output (CO) between compliant and noncompliant organs is an important determinant of the slope of the relationship predicted between CO and right atrial pressure (RAP). However, curves relating CO to RAP at rest are shifte

This study evaluates how mechanical factors impact cardiac output at the systemic level, and how mechanical factors influence muscle blood flow at the local level. Importantly, the two are intertwined; events that work locally in the periphery to aug

In humans, +Gz exposure immediately preceded by exposure to zero or -Gz can result in unexpected incapacitation ("push-pull" effect). Our goals were to establish whether this phenomenon exists in rats and to evaluate the importance of varying the dur

When oxygen delivery to active muscle is too low for the ongoing rate of metabolism, metabolites accumulate and activate a muscle chemoreflex that raises arterial pressure. During static muscular contractions, the latency of the onset of increments i

Net transfer of blood volume into or out of the cardiac chambers should have the same effect on central venous pressure as does transfer of an equal volume of blood to or from peripheral organs (e.g., spleen, or liver). We studied five pentobarbital

Ischemia of active skeletal muscle induces a reflex increase in sympathetic activity, heart rate, cardiac output, and arterial pressure, termed the muscle metaboreflex. Whether this pressor response contributes importantly in the regulation of blood

We tested the hypothesis that rapid increases in muscle blood flow and vascular conductance (C) at onset of dynamic exercise are caused by the muscle pump. We measured arterial (AP) and central venous pressure (CVP) in nine awake dogs, eight with atr

At rest, central venous pressure (CVP) falls when cardiac output (CO) rises. This can be attributed to flow-dependent redistribution of blood volume from central to peripheral blood vessels. In contrast, CVP rises during dynamic exercise despite a ri

Myocardial oxygen consumption (MVO2) includes components for 1) mechanical energy generation, 2) activation, and 3) basal metabolism. Whereas the first two components are expected to increase in proportion with heart rate, a significant basal level o

Graded reductions in hindlimb perfusion in dogs exercising at 2 miles/h (0% grade) elicited reflex pressor responses by what is referred to as the “muscle chemoreflex.” To determine the extent to which arterial baroreceptor reflexes oppose the mu
