The Oxygen Hemoglobin Dissociation Curve EXPLAINED!

There is a special relationship that exists in our blood between the amount of oxygen thats available and the percentage of hemoglobin that is saturated. This relationship is often represented as a graph which we commonly refer to as the oxygen-hemoglobin dissociation curve. Depending where our patient is on the curve it can tell us different things, as well as we have physiologic changes that take place, both naturally at different parts in the body as well as a result of various disease or other external processes that can alter this relationship. These alterations can result in right shift or left shift of the curve and have very different effects on the use and availability of oxygen.

this is literally the first time I have heard this explained as a dynamic physiologic process, in different stages throughout the metabolic process, as opposed to a stagnant "state of being". It makes much more sense now.

[fatimaalazzeh]

A as much I wanted to cry cause I couldn’t understand this concept. I want to hug you and thank you. May Allah bless you your explanation is perfect. You saved my life. Thank you ❤😭😍

[melikibrahim]

Thank you so much!
So many other channels who explain it just dump it on you and say they made it easy to memorise... You're one of the only channels who explained it with the physiology so that I could properly understand its relevance to clinical practice!

[Anuragyadavhand]

Broo i am in 11 class
And you just make me understand the whole concept
I wish that more teachers like you teach on YouTube.
👍

[MaLu]

i ve been trying to understand this since may. i have an exam tomorrow. you just saved me . thank you

[lalalabrianna]

This was a top tier explanation, i've never heard of this concept until studying for CCRN, and oh my god very very intriguing! THANK YOU!

[BarnBaby]

I'm an RVT studying for anesthesia specialty boards, this was so helpful! Thought you might find it neat to know your videos are helping animal patients, as well as human patients :)

[micahzuk]

Thanks for the video! This REALLY helped my understanding of the oxyhemoglobin disassociation curve! Big help! Thanks again!

[ANNREBECCAASIO]

Thank you for this video, it has been of great help😍

[nia-ssfq]

This is the best explanation. Totally makes sense now. Thank you 👍🙂

[alioid]

Smoothest yet most useful explanation thanks !!!

[roland.j.ruttledge]

Brilliant, as ever. Have saved for when I become more intelligent!! For now me and my pulse ox have something to aim for! Many thanks as always, Roland UK

[qkqwsbx]

Thank you so much ! I needed this for my accelerated nursing program. we just started on respiratory/ gas excchange.

[shafter]

Excellent vid once again and really helped get us listeners more depth on the curve. One thing if I could suggest it is (for us in the UK) it might be nice when talking about partial presures to also add the measurement in kPa as we don't look at it in mmHg. Might help someone but I guess it's not too hard to convert... Thanks again ICU Advntg...

[mariaperez]

Thank you for much for explaining this in ways that I am able to understand.

[Daniprincesita]

Such an amazing video! great explanations thank you

[bassamalbarkawi]

Thank you so much for making it truly easy to understand!!

[unliuniverse]

You explain very well. I have an exam next week.I am just curious about how you look like. 😊Hope you read this haha. Kudos to you sir🎉🎉

[camilanicole]

Awesome video king!<3 you explain everything so perfectly, my proff could never.
