Mar 7, 2004 · To keep it simple... AFterload = the pressure the heart pumps against... Essentially, it's equal to aortic pressure... Therefore, in HTN, the afterload is increased! Or in aortic stenosis, the …

Apr 14, 2011 · So FA2015 Page 305 notes that nitrates decrease preload >> afterload. When I think of nitrates, I think venodilation, whereas arteriolar dilation makes me think hydralazine. Then I see this …

Jul 5, 2009 · I've seen different sources say different things. So far my understanding is Handgrip and Squatting work the same way. They increase both afterload and preload thereby enhancing AS and …

Aug 9, 2014 · What exactly is "rapid squatting" (in First Aid)? I understand how "squatting" increases afterload, but FA says "rapid squatting" increases preload.

Aug 23, 2005 · Left-sided heart sounds are best on expiration b/c it moves the heart closer to the chest wall. Right-sided heart sounds are best heard with inspiration b/c of increased preload due to …

Oct 9, 2010 · Therefore, an increase in afterload would cause an increase in pressure and volume in the LV thus pulling the leaflets down. You can think of preload the same way.

Nov 27, 2020 · This is a "preload" vs "afterload" question. Simplified greatly here, dynamic exercise promotes preload (large volume of blood rushes in, stretches heart, ). RT is more afterload (ventricle …

Jan 21, 2015 · Why is afterload increased in hypovolemic shock? I get that you have volume/fluid loss in hypovolemic shock. Therefore you would have less blood to pump through the aorta and also a …
