Healthy or CO POISONING?

Carbon monoxide (CO) can misleadingly lead to high readings on pulse oximeters (devices that measure the oxygen saturation (SpO2) of the blood, because these devices are not able to distinguish between oxygen and carbon monoxide.

CO binds to hemoglobin in red blood cells with a much higher affinity than oxygen—approximately 200 to 250 times stronger.

This is because the oximeter measures the saturation of hemoglobin with what it assumes to be oxygen, not distinguishing between oxyhemoglobin and carboxyhemoglobin.

Consequently, a person with carbon monoxide poisoning might have a falsely high SpO2 reading, masking the life-threatening reduction of available oxygen to the body's tissues.

And the pulse oximetry reading only picks up that something is bound to the hemoglobin, but not what is bound to it.

Let’s say it together folks treat your patient not your equipment

Very important point you made there. Could also mention about other factors that lead to an incorrect reading like dirty fingers, bright sunlight and movement.

The affinity of CO to hemoglobin is even 200 times more than oxygen. And in case it wasn’t mentioned, you’ll see similar symptoms to that of hypoxia, headache, dizziness, loss of consciousness, etc. Love the videos!

Look at the patient not the machine it's a contact sport😂

Interesting ! And compliment for the gshock ;)

I've been smoking 12 years a pack a day on the facade that my brother did stuff my cousin did stuff my aunt allowed them to get away with it and my dad joined in after he cheated on my mother and got hep c and gave my mom hep c.

Damn son damn amazing yeah never trust the monitor brilliant sir

I'm beginning to trust capnography over pulse oximetry.

carboxyhemoglobin, when carbon monoxide is bonded to ur red blood cells, it has an affinity that is 240 times stronger than oxygen meaning once it binds to ur heme it stays there, it''s positive charge stabilises the iron ion in the centre of the heme making your oxygen stick not allowing it to go out the red blood cell
