O2 Dissociation Curve (Part 2)

[jacklikesjuggling]

This helped me get to grips with the concepts, thanks!

Thanks for posting this!

good video For MetHb curve switches to left on venous torrent since Hb wouldn't realease O2 easily as u explained. In pulmonary circulation since Hb has Met binded to 1 of it's 4 sites less O2 is able to bind Hb while PA O2 increases, increasing A O2- aO2 gradient. Since O2's solubility in blood it's not good enough to compensate MetHb inability to carry O2 the curve most likely move to right: Pej Pulmonic Valve Stenosis w VSD! love..

very good explanation!!

acidic cell poop..lol

I'm a physiotherapy student and struggled grasping all the respiratory side of it untill I watched your videos. THANK YOU! :)

[xdanielxcastrox]

the chart at the end of the video says that a decrease in pH causes a LEFT shift and an increase in pH causes a RIGHT shift, but earlier you had explained it the other way, so just wondering which one is correct?

by the way, thanks for the videos, they are super helpful. our RT instructor uses them in class sometimes. lol

@xdanielxcastrox Decrease in pH (tissues) causes O2 unloading (R shift). Thanks for catching that! I added an annotation indicating the typo.

why are you so awesome i failed this test but when i watched your video now i understand it better stay being awesome! have a nice day:)

"Co2 is like cell poop"... classic!

[RespiratoryStudent1]

@ro2778 Gross, but true!

I'm revising for my AS Biology Unit 2 exam on Friday and found this video really helpful, especially the summary at the end with what causes the shifts.

Thanks for making this video

[RespiratoryStudent1]

@IanRanson Glad it helped!

[miketheman247]

I'm studying for the MCAT, and these explainations are extremly helpful. Thank you very much :) !

[RespiratoryStudent1]

@miketheman247 You're welcome, glad to help!

[MsNeonlily]

Thanks for doing this! It really helped on my Physiology exam.

[RespiratoryStudent1]

@MsNeonlily Good, hope you did well on your exam!

Which of the following pulmonary function measurements would normally have the smallest predicted normal value? A. IRV B. TLC C. VC D. IC

[RespiratoryStudent1]

@Richsuits7

TLC = RV + ERV + VT + IRV

VC = ERV + VT + IRV

IC = VT + IRC

IRV = IRV

Based on how these are calculated, you should be able to guess which would have the smallest value (IRV).

[RespiratoryStudent1]

@RespiratoryStudent1 IC = VT + IRV (not IRC)

thanks for your help =)

@lizr949 You're welcome!

Thanks for the information on Dimensional analysis. I have not had an easy time finding help with dosage calculation on internet in reference to how RT would use it. In reference to the other question, yes, I did mean O2 with masks and delivery devices.. Thanks again for all your help you are excellent with explaining!!

[klb4526]

Would you consider doing videos about dosage calculations in reference to diluents? Also, medications such as beta-adrenergic, catecholamines, etc and finally, O2 administration?

[RespiratoryStudent1]

@klb4526 Unfortunately, our class hasn't covered respiratory pharmacology yet. For dosage calculations, there's so many good videos on youtube to watch. Dimensional analysis helps a lot with setting up those types of problems! For O2 admin., do you mean like O2 masks and delivery devices? I've been meaning to post a video on that material.
