The PF ratio is a useful and quick tool that we have at our disposal to quantify the degree of respiratory failure that our patient has. Having this easy measurement also allows us to trend our patients respiratory failure to determine if they are stable, improving, or deteriorating. It's a simple calculation of just dividing the PaO2 from an ABG by the FiO2 expressed as a decimal. We can also use this PF ratio to then see test how our patient would respond to differing levels of oxygen delivery.
NOTE: Its dissociation not disassociation curve 🤦🏻‍♂️

This was super helpful! We see a lot of discrepancies with high SpO2 and low PaO2 in the ICU and many times families will take the high SpO2 as a good thing. This will definitely help me explain it better to patients families! Thank you!

i was just talking about the PF ratio to my preceptor during my ICU rotation and he was explaining this to me a bit. This helps me understand better for sure and I love that I will now be able to throw around the term oxyhemoglobin curve

The way you explain makes the process easier to understand. Thank you so much. This has improve the way I now trend my patients and not having to rely so heavily on the RT, especially when they are occupied in other departments.

I had someone close to me who died recently of sepsis. ARDS was ... bad. FIO2 was 0.75. My husband had to look at what this meant. I did the math with a theoretical 100 for the PAO2... My God. 27 and something on room air. Hurts my heart to think about. But it puts things into perspective. Feel like I'll never complain about my asthmatic airways again. There was a lot going on, but this was the one number I had. Thank you for explaining...

Hi my question is, same SpO2, what causes some patients have much lower PaO2? Does Ph affect it?

@doctorsquirl4964 2 жыл бұрын

Yes! Temperature, 2,3-DPG and pH all effect it. Looks up shifts in the oxygen dissociation curve and it will explain it further.

There's slight mistake at 5:48, pls review it. when PaO2 = 42% the SpO2 =77.sth, but it's been tallied with PaO2 40%. Thanks

I have different folders depending on the series, but it'll mention which folder to find them in. Let me know if you have any questions!

I realise that I'm fighting a loosing battle here and there's not much you can do to fight it ....because medics and maths... but it's not a P/F ratio, because it's not a ratio - it has dimensions which is why it needs correcting for units.... ah welll....
