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.

[@ICUAdvantage]

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.

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.

But I came across a video where it says that oxyhemoglobin and de-oxyhemoglobin absorbs lights of different wave length and on the basis of it's absorption ratio Oxyme. Gives us the readings 🤔 now I'm confused about ur comment

[@yucao6294]

When CO binds to hemoglobin it changes the light absorption properties. Free CO molecules absorb at a high wavelength around 4600 nm, but when bound to Hb, this shifts to 940 nm, overlapping with oxygenated hemoglobin. Both HbCO and oxygenated Hb absorb very little red light at 660 nm, causing pulse oximeters to give false readings. Since their absorption wavelengths overlap, the device cannot tell the difference, making it seem like there is enough oxygen in the blood when there is not. hope this helps

[@iamasaint_5727]

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!

[@ICUAdvantage]

Thank you so much! Glad they are helpful for you and I def plan to keep making them!

[@gretchenvankeuren887]

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!

[@ICUAdvantage]

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! ❤️

[@MikeDahlin1]

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 KZbin! Extremely helpful description of what those numbers mean. The good news is, I'm in good health! Thanks so much for your recording!!!

[@biswalashis123]

Very informative video

[@brettduce5243]

SpO2 is used to determine hypoxemia not hypoxia. Hypoxia describes low oxygen in the tissues, hypoxemia describes low oxygen in the blood.

[@ICUAdvantage]

Yup my error

[@roland.j.ruttledge]

Nice ☺️ my carry - pulse ox (with pi), glucometer, and thermometer are invaluable. Great video as ever, Roland UK

[@ICUAdvantage]

Nice. Yeah, having a portable pulse ox is so easy to have available these days!

[@xyanicsheith]

Am doing a project about pulse oximetry and this has really helped me alot.. thank you

[@markdefensor751]

nice video, very informative! I do appreciate the creator's effort to help

[@53luis]

This made it so simple to understand, thanks!!

[@ICUAdvantage]

Awesome! Really happy to hear this!

[@nur-isahasad2968]

Please made a free quiz😢 thank you.

[@Heleous281]

Is it possible to discern any cardiomyopathies via pleth? Or is it only good for heartrate? Love these vids man..keep it going!

[@ICUAdvantage]

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.

[@Heleous281]

@@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!

[@mikeyyuangu2546]

Thanks Soo much ❤

[@ICUAdvantage]

You are very welcome!

[@SatumainenOlento]

Excellent video btw.!!! 👏

[@christinabeahan8596]

Thank you for the video!!

[@lobarita]

Thank you Mr. Watson

[@ICUAdvantage]

No, thank you Mr Martinez!

[@SatumainenOlento]

What does the PI% reading mean? Could you do a video as it is hard to find information about it.

[@mdinzamamun6927]

Great 🤞

[@ICUAdvantage]

Thanks!

[@tomt810]

I had a professor who once told us to make sure our patients weren't (FTD)... ...fixin' to die...

[@laurashapka8440]

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

[@ICUAdvantage]

Haha yes! By far the best way to say it

[@paymenomind1604]

Will you or have you done a video on the oxygen dissociation insanity?

[@ICUAdvantage]

Already done. kzbin.info/www/bejne/mZXck6auebadrsk

[@ashasyam6019]

Is there something like pulse index

[@gabover]

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 ?

[@otto9875]

Pulse oximetry is a Quantitative value for Hypoxemia. Not hypoxia. Bonus points :)

[@amirabbasbaharfar2328]

Done.

[@mradnan2164]

Thank you so much very very much 🖤 explain English mein kya apne

[@paymenomind1604]

Pleth refers to plethora which is Greek for an excess of blood.

[@karlyuteriz8340]

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?

[@twylah9047]

My God... I don't want to be a DR. I just want to know how to read this pulse oximeter.
