What is difference between SpO2 and PaO2 levels, | RegularCrisis

#spo2andpao2levels
Spo2 and pao2 are very frequently measured and used in ICUs and ER.
In the above video we try to find out the difference between them.
#regularcrisis
regularcrisis.com is dedicated to doctors and nurses who regularly manage crisis like situations in ICU & ER.
Intensive care unit and emergency department are the backbones of any hospital where all critical situations are managed. Everyday is a crisis like situation there and with time the team working there get used to it with. With time, their skill gets more sharpen with which they manage these situations more and more efficiently each time.
But most importantly, the experience which they accumulate is invaluable; their experiences teach them things which at times are not mentioned in the regular textbooks. What if this experience is shared with the doctors and nurses who are newly joined in ICU and ER!
Regularcrisis.com serves this purpose only. We share educational material (mainly videos and forums discussion) which is a blend of latest guidelines and rich experience of ICU and ER teams.
We hope that his small effort of ours will be of some help to those working in ICU and ER.
Update: regularcrisis.com is now affiliated with ESBICM* for creating educational videos for health care working in ICU and ER.
*Educational Society of Bedside Intensive Care Medicine
regularcrisis is founded by Dr. Ankur Gupta, an Intensivist.

Much better explained the physiology than many learned physiologists

[@yoo_adrian8915]

Very concise, simple explanation. Thank you!

[@drshalender5406]

Excellent presentation and explanations of the gaseous exchange of two important gases in our body via plasma to haemoglobin and vice versa. Kindly also explain how two main processes cause respiratory as well as metabolic imbalances following ARDS and MODS. thanks and regards.

Best video to understand this topic

Very much beneficial for. Mbbs or any medical student

Thanks for the english lecture

Thank you 🙏 doctor

Nice explanation sir its very importaint things for me

Thanks rahul , good to see u liked it

Extraordinary resemblance to SRK

You told me a great things today wow
Thanks

You are so welcome

[@wetretto603]

fantastic

[@SKGOELDELHI]

Awesome sir

[@xolico1]

As only 4 molecules of oxygen can be attached to hemoglobin, that means the spo2 level will always be multiple of 25 (25-50-75-100 %) in percentage. So why does it show 90% or 95 %. What would that mean ?

[@alsabafaheem2990]

That's the average of total haemoglobins

[@azizshakirsidd.5692]

because.. some of the RBC is bind with 2, 3 Molecule and some of 4 molecule.... it give u an average range

[@riteshchaurasia4953]

What if p02 is decreased in the body..what will be its effects

[@abhilashreddy897]

Thank you sir 🙏

[@deads4268]

Wonderful !!

[@riteshchaurasia4953]

Does increasing po2 will increase spo2..

[@FORTHEPEOPLE-rs6ei]

Dear Sir, can you please suggest the reason......My daughter age is 12 years and her SPO2 is going up and down sometimes it is showing below 90 (sometimes 60, 70 and 80) and sometime above 90 , RTPCT - Negative, CT SCAN - Normal and CRP Level - Normal

[@saqibmudabbar]

You probably have a non FDA approved pulse oximeter

[@pradeepkumarg2700]

Thanks sir ,pls explain about how many liters of oxygen has to be put for the patients based on their saturation levels

[@wahib786]

Thank-you sir much

[@dasdr4594]

How to calculate spo2 /fio2 level sir

[@TheICUChannel]

There is Nthg called Spo2 / fio2 level … it’s po2/fio2 level …
Suppose in ABG po2 is 200 and you are giving fio2 of 50% … then It will be (200/50)*100 … it will be 400

[@dasdr4594]

@@TheICUChannel sir when pao2 not available....then use spo2/fio2....and
spo2/fio2 < 316 then we called it as ARDS ,I read this in covid 19 guidline....thants why asked sir

[@TheICUChannel]

I haven’t come across this , I’m which guidelines ? Don’t think it’s scientific

[@dasdr4594]

@@TheICUChannel ok sir thanks

[@crazzymedico3678]

and in small amounts with bicarbonate

[@afreen2681]

Why pao2 drastically fall below spo2 below 90%

[@TheICUChannel]

It’s because oxygen dissociation curve is sigmoid

[@saqibmudabbar]

Because when hemoglobin is unable to get the oxygen it needs from the lungs or other sources, then it will take even what's dissolved in the plasma.
Another reason would be that when gaseous exchange takes place, hemoglobin more readily binds to the oxygen. But there's still remaining oxygen left in the plasma. The extra oxygen that diffused into the blood. However, when there's not enough oxygen, there's no extra ex l oxygen for the hemoglobin.
