Pulse oximetry measures the saturation of hemoglobin. That saturation isn’t necessarily oxygen. This is important to understand, especially for EMS workers. If someone was exposed to CO, the pulse ox can still read at 100%, because their hemoglobin is saturated… with CO (not O2). If your patient is an exposure patient and you throw a pulse ox on them and see 100% and assume they’re good, your patient may very well die.
Love these quick simple videos too. I passed my NCLEX-RN on Thursday and have been watching your videos for a few months through the end of school.
Nice man! Congrats on passing the NCLEX! Do you have a job lined up yet? Glad the videos have been helpful for ya
@@ICUAdvantage I am looking now as I just finished updating my resume.
Absolutely! Please continue these videos. I’m striving to become an ICU nurse and I listen and watch all of these videos closely. You’re showing and teaching us great information right here. Thank you!
Thank you so much! Glad they are helpful for you and I def plan to keep making them!
I've binged watched so many videos on your channel! I used many of these while studying for my CCRN in 2020, and am now using them again! Such good material, very concise and explained so easily.
Thank you!
Hey Gretchen! This is so awesome to hear. Glad to know they were helpful for you in your CCRN studying and that you are still finding them helpful to this day. Thanks so much for taking the time to leave a comment! ❤️
Am doing a project about pulse oximetry and this has really helped me alot.. thank you
I just bought an Innovo Finger Pulse Oximeter and after seeing the reading I thought to myself, what does this mean? So glad I found your TH-cam! Extremely helpful description of what those numbers mean. The good news is, I'm in good health! Thanks so much for your recording!!!
nice video, very informative! I do appreciate the creator's effort to help
Thank you for the video!!
This made it so simple to understand, thanks!!
Awesome! Really happy to hear this!
Excellent video btw.!!! 👏
Nice ☺️ my carry - pulse ox (with pi), glucometer, and thermometer are invaluable. Great video as ever, Roland UK
Nice. Yeah, having a portable pulse ox is so easy to have available these days!
Thanks Soo much ❤
You are very welcome!
Thank you Mr. Watson
No, thank you Mr Martinez!
What does the PI% reading mean? Could you do a video as it is hard to find information about it.
Please made a free quiz😢 thank you.
SpO2 is used to determine hypoxemia not hypoxia. Hypoxia describes low oxygen in the tissues, hypoxemia describes low oxygen in the blood.
Yup my error
Great 🤞
Thanks!
Done.
I also call it a "sticky finger probe". I get made fun of a lot at work for it! I'm glad I'm not the only one
Haha yes! By far the best way to say it
Thank you so much very very much 🖤 explain English mein kya apne
Thanks for the video. How do we explain the dicrotic notch (aka aortic valve closure) sometimes visible on the down curve since we do not measure pressure with the pulse oxymetry ?
Is it possible to discern any cardiomyopathies via pleth? Or is it only good for heartrate? Love these vids man..keep it going!
Interesting question. I know theres some research going into using the pleth to analyze BP and SV, so potentially, but nothing that I've seen personally yet.
@@ICUAdvantage Thanks for the feedback...If possible, this would be revolutionary if pleth readings could be used to identify patterns associated w arrhythmias, MIs, etc..would save alot of lives w such a proactive screening approach..will have to delve more into this!
Will you or have you done a video on the oxygen dissociation insanity?
Already done.

Is there something like pulse index
Pulse oximetry is a Quantitative value for Hypoxemia. Not hypoxia. Bonus points :)
Pleth refers to plethora which is Greek for an excess of blood.
I guess a dumb question is how/why is it normal to have a value of 99-100%? If our body is using oxygen - wouldn't our hemoglobin be less saturated as we use it, or, as we breathe (oxygenate?) are we replacing the oxygen we use almost immediately so that's why it doesn't really drop?
My God... I don't want to be a DR. I just want to know how to read this pulse oximeter.
