Preload is know as the end diastolic pressure, aka the pressure at the end of DIASTOLE (when ventricles are about to be finished getting filled). So basically how much pressure is at the left ventricle before it wants to contract blood out to the aorta. After load is the pressure the ventricles need to overcome (reach) to cause the left ventricles to contract and eject blood to the systemic tissues. Frank-starling mechanism says that the more amount of blood volume you have before you contract (aka end diastolic pressure aka preload!!) the more blood you will eject when your ventricles contract. So the more blood you have before you contract, the more you pump out.
This literally helped me SOOO much - thank you Simple Nursing!! I am a second semester prenursing student, and these types of videos literally save my butt in exams!! These type of channels are what made me want to start my channel, which is about my pre-nursing experience and my journey towards me getting my BSN. Thank you guys!!
I think the animation causes confusion. The animation demonstrates the filling of the ventricles beyond the systemic and aortic values as preload is being defined. That process obscures the very definitions being explained, most particularly for the learning student who is repeatedly reviewing the animation for clarity.
If the pathway is narrowed and is resisting the flow (higher after load) then obviously little amount of blood can flow (stroke volume).. So higher the afterload lesser the cardiac output and viceversa
Afterload is simply the pressure being exerted by aorta on the blood that is trying to flow out of the left ventricle (which is basically the cardiac output). So when afterload decreases cardiac output obviously increases.

this is better than the video tbh imo
Great that you were willing to add on the the principles in the video. Thanks
thank you
Thanku
I took a screenshot ✨️

This is the easiest explanation to understand about preload and afterload. Thank you.
super simple and to the point. thank u man!!!!!

I swear, sometimes the video just confuses you more.
Thank you so much, nurse Mike!
I'm don't understand why when the afterload decrease cardiac output increase
If the pathway is narrowed and is resisting the flow (higher after load) then obviously little amount of blood can flow (stroke volume).. So higher the afterload lesser the cardiac output and viceversa
Afterload is simply the pressure being exerted by aorta on the blood that is trying to flow out of the left ventricle (which is basically the cardiac output).
So when afterload decreases cardiac output obviously increases.
Why why don’t understand it’s very hard 🫠
....."loads of problems" great little video
Clickbait. Put the info in the video don't link out to your other website
