By the way, the reason that the MAP is about 1/3 of the difference between systolic and diastolic pressure is because the heart spends about 2/3 of the time in diastole (relaxed) and 1/3 of the time in systole (1/3), causing the mean to be closer to the diastolic pressure.

@@terryernest6264 It has nothing to do with the size of the heart. It is about the time spent in diastole vs systole. Even if they were different sizes, this principle still applies.

Yes bro... MAP IS THE PRESSURE THAT IS EXERTES AND USED TO DRIVE THE BLOOD IN ARTERIES FOR ONE CARDIAC CYCLE... HOPE YOU UNDERSTAND😉
@jelleleeuwis43532 жыл бұрын
@@alias1267 ti’s the mean value, not the average value. The reason for this is because during a cardiac cycle the heart spends more time in diastole than in systole. MAP computes as: MAP = Diastolic BP + [0.333 (Systolic - Diastolic BP)] Hope this helps!

Lets say you measure and patient has BP 180/170 would you take it town and record or think something wrong with measuring? If you think its wrong, what no. Difference then is adequate difference between systole and diastole that will make you take it to record.

Can someone explain to why increased SVR results to increase cardiac output? I still don't get it why these are proportional. I know there's something wrong about my understanding because the way I see it if there is increased resistance that means it can't easily pass through so why the output increased if resistance is also increased😂. Please someone explain
@Letlhogonolo20204 ай бұрын
Hi, I think instead of thinking of th volume passing through, rather think of the pressure the blood put on vessels when they are narrow as opposed to when the vessels are larger. Hope it helps.
@Letlhogonolo20204 ай бұрын
When the blood vessel is narrow, the PRESSURE will be HIGHER
@Freon9144 ай бұрын
@@Letlhogonolo2020 Thank you for the answer. Yeah I guess it's when the blood pressure is high the left ventricle pumps harder hence the increase in cardiac output.
