Total peripheral resistance meaning
Vascular resistance is the resistance that must be overcome to push blood through the circulatory system and create flow. The resistance offered by the systemic circulation is known as the systemic vascular resistance (SVR) or may sometimes be called by the older term total peripheral resistance (TPR), while … See more Units for measuring vascular resistance are dyn·s·cm , pascal seconds per cubic metre (Pa·s/m ) or, for ease of deriving it by pressure (measured in mmHg) and cardiac output (measured in L/min), it can be given in … See more A decrease in SVR (e.g., during exercising) will result in an increased flow to tissues and an increased venous flow back to the heart. An increased SVR will decrease flow to tissues and decrease venous flow back to the heart. See more The regulation of tone in the coronary arteries is a complex subject. There are a number of mechanisms for regulating coronary vascular tone, including metabolic demands (i.e. hypoxia), neurologic control, and endothelial factors (i.e. See more The basic tenet of calculating resistance is that flow is equal to driving pressure divided by flow rate. $${\displaystyle R=\Delta P/Q}$$ where See more There are many factors that alter the vascular resistance. Vascular compliance is determined by the muscle tone in the smooth muscle tissue of … See more The major determinant of vascular resistance is small arteriolar (known as resistance arterioles) tone. These vessels are from 450 μm down to 100 μm in diameter.
