I have been a nurse for 20yrs and this video break BNP, Cardiac output,preload and afterload down amazingly.

[@emtgecko421]

THANK you...! in 11 min I understand it even better and more with more knowledge instead of the very long chapter book.. Please keep these videos coming.. it really does help!

[@taleishasaunders2789]

This video summed up 15 pgs of lecture notes in 11 mins for me! I understand it all now and your video pulled it all together! Wish me luck on this exam Thursday! ....Now I'm going to search to see if you have any videos on HTN! :) Thank you!

[@brownking]

I graduated with my Masters in Pharmacy, and I'm currently writing my board exams to get licensed in Canada, and I've stumbled across your videos and you really do simplify all the mechanics behind all these topics, it's beautiful! Subscribed!

[@tashamiller6405]

I'm a senior in the TBSN-- and it's my last semester! There is a lot in this video that I should have understood semestersss ago!! This really makes everything so much simpler and easy for my brain to grasp. Thanks so much for all these videos and thank you for allowing them to be free! Life saving!

[@isodamfly]

I didn't even know you were a nurse until you said simple nursing.com at the end. I thought you were a doctor.......fantastic job...have a test on the heart tomorrow..needed this

[@alli1590]

i have my cardiac exam tomorrow! i've been watching your videos nonstop for the last week. they have helped me understand things so much easier than just reading from a textbook. keep up the good work! now i just have to pull all the i formation i have stored out of my brain and pick the "most right" answers! :)

[@nykleigh]

[@chocowate]

Thanks for this video. Whenever I am reading my book, I feel like I'm trying to read Chinese writing but you basically interpreted in a much simpler English language!

[@jessygarzon1002]

Why can't things be explained this easily by professors in the classroom? Thank you! Your videos are helping me get through nursing school!

2nd semester student here. This video just made me realize that I understood what I was reading, but it also helped me put the puzzle together..thank you !

[@mindytran436]

I'm a new grad going in Trauma/SICU, your videos are great review and refreshers than the modules they're having me do! Thanks for the videos and I'll pass your videos along to other students I still know.

[@sangreDEzombies06]

SO tremendously helpful. I wish I would've known about this video 2 years ago when I was in A&P....instead, i just struggled through it. My pharm instructor assigned this video, and now, I really get it! Thanks so much

[@stefanieormeche8268]

I am a Physical Therapy student - and this helped very much! Your videos are for more than just nursing students! :-) Health Science Majors - take a look!

[@Marie0304]

I'm taking the Med-Surg Certification exam in the next couple of the months and this is very helpful for review. Even after you have been nursing for 18 years, you still need reminders!!!! LOL You do a great job! Thanks!

[@sophi_does_stuff]

The way you presented this information made it so easy to understand! Thank you! l look forward to watching more of your videos

[@elinmogollon4690]

[@dorismurphy61]

Your videos have been so helpful to me. I share them with my classmates. Thanks!

[@denrave26]

Thank you so much for these videos! I am in my last semester of nursing school and your videos are helping me tremendously!

[@juanhmaldonado]

Excellent video and easy to understand. However, my instructor said in class that BNP is actually produced by the ventricle cardiomyocytes, not the brain. Thanks for the video.

[@wendymejia9636]

first year medical student here... simple, yet very informative!!! thank you so much! :)))

[@NurseKillam]

Great video! I will be sure to share with my students. It is great to see other nurse educators out here making learning accessible.

[@jacksterkitchen]

Awesome video's! I'm going to start in the ICU tomorrow and with all the extra education I have to do, your video's help me remember the basics and thus build the foundation of knowledge needed to continue and learn more. Thanks and keep it up. :-)

[@tamaradorsey7926]

OMG I am going to get an A+++++ after all this time I get it. I owe it God and you. Thank you so much.

[@xXBoniita]

Had a hard time understanding what preload and afterload meant. This really cleared it out for me Thanks!

[@ElleGeeFive4]

OMG I didn't think this was going to help since we haven't learned about BNP...but it really did. Thank you SO SO SO much.

[@caseyqli]

Your awesome, helps a lot, getting 70% and below and the first time i used these videos for study i got a 90% highest grade so far in pharm

[@lauralunger5532]

really nice way to break things down...this stuff is important to know the cardiac meds which is why I wanted to look at this video...this helped a lot...sometimes you have to go back to the beginning...this was a quick review for me! thank you! :)

[@VanessaGabriel42611]

You are SO awesome! I am a first semester nursing student & pharmacology seems to be a harder class for me but you explain this material so well and I understand it so much better now!! Thank you!!

[@hyunee_15]

thanks for the explaination.now i understand about the cardiac output,preload and afterload.these things are really confusing me..

[@alimerritt2362]

thank you for the help! this nursing student really appreciates it!

[@creiji]

plain and simple love your videos keep doing what your doing. Thank you mike

[@colescott5920]

Pre-Load is equal to EDV. (the amount of blood that enters the ventricle following ventricular diastole) After-Load is dictated by MAP. As arterial pressure increases, the ventricle has to work that much harder to reach and exceed the pressure of blood within the aorta. If the ventricle is unable to match &/or exceed the pressure in the aorta, then the semi-lunar valve at the LV entry point to the aorta will not open. This increased resistance/lack of CO is what leads to pulmonary edema, decreased EF, and potentially cardiac arrest if left untreated.

[@sashaalliman1652]

That's so much, I finally understand what preload and afterload is! YEAH!

[@SimpleNursing]

oh yes they did!!! I just recent had a patient with 45,000

[@kellyphares3035]

Wow super helpful! Learned more with this video!

[@tinaearnest1458]

Excellent, thank you for making these video's. I will let you know how much they help on my test when we take it in a week. I needed someone to make this crazy stuff english for me. Again thanks.

[@CarlosRomero-yr5xq]

Very helpful stuff Michael! Thank you so much for your teachings. Few questions, Does the stroke volume used in the calculation of cardiac output take into account aortic valve regurgitation? What is the stroke volume if the left ventricle pumps via aortic valve 80ml during systole and receives back 10ml because the aortic valve leaks during diastole? Is the SV 80ml or 70ml? and what the cardiac output would be if the heart rate is at 70 bpm?

[@krystinemilewski629]

This was extremely helpful. Thank you for putting this together.

[@dowde]

That was a perfect explanation!

[@judeschumaker4509]

I'm still a little confused about preload and afterload. So is preload the stretch itself inside the ventricles? And afterload is the pressure in the arteries that the ventricle is trying to pump blood into and though?

[@salinajj]

great video keep them coming...

[@nicandermedalla9806]

cool man, need that for my boards

[@PRodriquez1943]

"BNP is named as such because it was originally identified in extracts of porcine brain, although in humans it is produced mainly in the cardiac ventricles." thanks Wikipedia
