SpletSVR typically increases slightly, particularly if sympathetic stimulation augments MAP. Compensatory mechanisms begin to fail with a 20% to 25% volume loss. Mild-to-moderate hypotension and decreased CI may be present. Orthostasis (with a blood pressure decrease of 10 mm Hg and increased heart rate of 20 to 30 beats per minute) may become apparent. SpletThis crossing point of the two curves represents the steady-state operating point defining the cardiac output and right atrial pressure for the particular physiological conditions represented by the cardiac and vascular function curves. In this example, the CO is 5 L/min at a P RA of 0 mmHg (point A). If SVR were decreased by administering an ...
