Figure 4. Schematic of the effect of thermal stress on Frank-Starling relations. Panel A represents normothermia with the labeled point being the operating point. Panel B represents associated changes in the curves related to heat stress and cold stress as well as the location of the supine operating points on the curves. Panel C highlights slope changes in the curves where a similar decrease in pulmonary capillary wedge pressure would cause a relatively large change in stroke volume during heat stress and a relatively small change during cold stress.
