Hemodynamic Factors Affect Blood Pressure
Various hemodynamic factors, such as SV and CO, affect a patient's blood pressure. Fluctuations of these hemodynamic factors can also indicate a related condition. nnStroke Volume nnA patient's SV, the amount of blood pumped from the left ventricle during systole, is usually about 70 ml per heartbeat. Three factors affect SV, preload, afterload, and contractility. nnPreload is the force of blood in the ventricle exerted on the ventricular muscle at the end of diastole. The mo
