What Is The Relationship Between Cardiac Output And Blood Pressure
Blood pressure is a measurement of the force placed on the blood vessels and is comprised of the "systolic" pressure (the top number on a blood pressure meter) which is the peak pressure when the heart is pumping, and the "diastolic" pressure (the bottom number on a blood pressure meter) which is the pressure during the resting phase ...Read more
Mathematical: The relationship can be expressed as a variant of darcy' law; flow (q) = pressure/resistance. In the human circulatory system: q = (map – rap)/tpr (map = mean aortic (or arterial) blood pressure in mmhg, RAP = mean right atrial pressure in mmhg and tpr = total peripheral resistance in dynes-sec-cm-5.) however, as map>>rap, , this can be simplified to: q~map/tpr. Map is obviously affected by htn. ...Read moreSee 1 more doctor answer
Heart failure: Long-standing hypertension (or high blood pressure) leads to left ventricular hypertrophy, and if untreated, can eventually lead to congestive heart failure and decreased cardiac output. Hypertension is also a risk factor for stroke and coronary artery disease (another potential etiology for decreased cardiac output). ...Read more
Starling mechanism: You mean how does venous pressure regulate cardiac output.similar to the Starling mechanism-by increasing pre load. Up to a certain point cardiac output is directionally proportional to venous pressure assuming that everything else is the same such as the after load or cardiac contractility ...Read more
