I use all of the Khan Academy videos while learning all types of topics in nursing school. Wonderful learning tools!

Afterload is the tension the heart must produce to force open the semilunar valves and eject the blood. EDV (end diastolic volume) is the volume left in the ventricle after filling. SO ESV-EDV= stroke volume. Make sure to make a comment under that part of the video so students don't get confused why studying. Other than that, great video!

I think that you made a small mistake when describing afterload. Afterload is not the amount of blood left after ejection of blood, but rather the pressure that the heart has to build up, in order to eject blood against the pressure of the blood that is already in the cardiovascular system within the arteries. The amount of blood left after ejection is known as the "left ventricular end systolic volume".

Wow. Now I clear off all the mysteries about it. Thank you so much, sir.

These are great learning tools! I am going to show your videos to my nursing professors, thanks!!

Hemoglobin/hematocrit can also be increased, due to concentration. In fact, my nursing book specifically points out that it can be raised, but not the possibility of a decrease (though, that does make logical sense to me-blood out = lower levels).

[woodpeckersonfirs]

Hi, could you clarify whether the vasoconstriction happens in the venous or arterial side? To increase SVR, I believe the arterioles vasoconstrict to divert blood to essential organs.

Que bueno eres para explicar informacion. Muchas gracias amigo ayudo mucho! :)

[drphysio]

thanks a lot...I was nuch confused about physiology of shock...it helped m a lot from concepts to end treatment...❤

Love you Khan let me go update my account!

my mother died on what they call hypovolemic shock.but in our hospitals there is a lot of negligence

[johnjerge]

wouldnt you say the h and h could be high if it wasn't due to blood loss but because of other fluid loss?

[aprilmagistrado]

Can blood transfusion save Hypovalemic shock?

[ansumandatta]

You are claiming that hematocrit count goes down but doctors say it goes up. Please consult professionally and correct. Remuneration accepted by me gratefully.

[mobenkane]

After load is not end systolic volume … period

YOU NEED TO MAKE IT I HAVE IT ON MAX AND CAN HARDLY HEAR IT

(Not so) fun fact: this is how Selena died

[adhamhussiun]

i know that we should't give the patient adrenaline but why ?
