Oxygen Dissociation Curve Explained - Bohr Effect

Oxyhaemoglobin dissociation curve explained by Patrick McKeown

SPO2:
Measures how fully loaded is hemoglobin with oxygen.

Amount of oxygen dissolved directly in the blood:
Measures amount of oxygen dissolved in blood.

It's an S-shaped curve. If you breathe hard the curve shifts to the left. So the oxygen dissociation curve shifts to the left and hemoglobin holds on to oxygen.

This is called the Bohr Effect.

Patrick. You're a beast. No other video made as much sense as this one lol

This is the best and most easy way I have found to describe this, thank you so much

I find it very appalling that those simple things are not taught at school.

I'm in the midst of the process of switching to nose breathing and happened
to finish my first halfmarathon lately. Even played soccer merely recruiting on
nose breathing, including some sprints.

It all feels natural, but due to 48 years of wrong conditioning still somewhat
uncomfortable.

Thanks for all your dedication and the great work you do! Your book is
truly a gift and I enjoyed reading it.

THIS WAS REALLY HELPFUL IN UNDERSTANDING OXYGEN-HEMOGLOBIN DISSOCIATION. I HIGHLY RECOMMEND IT AS A FIRST STEP TO UNDERSTANDING.

The hard breathing he is referring to is actually hyperventilation. That is what lowers carbon dioxide, which prevents oxygen escaping into the cells

I love stuff like this. Helps me with my cardio. Thanks!

[natacaomasterbrasil]

thats why wim hof method demands those 15 seconds holding the breath after each round of deep breaths. it brings balance.

[Achesoul]

Wow. Thanks for a great explanation:-)

[tzerenyap]

Awesome explanation, easy to understand! Thank you!

[Departedreflections]

this shit should be taught in public schools

Well, if muscles have high co2 from cell respiration and muscles runs at high Temp, and are building up lactic acid, you really don’t need to change anything .

Is there not a CO2 tester that can give us real-time blood levels?

But when i'm in an intense aerobic exercise, i'll eventually have to "breath hard" because my body demands it, so what's the solution? try and breath deeply and slowly instead ? it seems a little counterintuitive to me that the body is constricting you on purpose in intense aerobic scenarios.

Nose breathing is nearly impractical with a deviated septum. If you have difficulty breathing through your nose, see an ENT doctor (otolaryngologist) and have your nasal passages examined.
