If you want to monitor your heart rate and pulse oximetry you can give a look at my post describing step by step how to use ESP32 with a heart sensor:

Uworld said that in carboxy hemoglobin the pulse oximetry does not differentiate it from oxyhemoglobin - so it is not reliable and we need to do an ABG (I hope I am correct about this).
For methemoglobin, however, they say that pulse oximeter shows readings around 85%- what does this imply??
Thanks in advance!
I am looking for the schematic for the GE TruSat Pulse Oximeter. Looking at a bad resistor on the system board and am trying to repair the board.
From it's location I'm thinking it's the sense resistor for the power supply. I can post pictures if needed.
Interested to see studies the community would reference in general and for specific brands of pulse oximeters for personal use by a patient being sent home on oxygen.
I am hoping for education on the use of finger-probe pulse oximetry. Sorry for long post, just wanting to provide info. As a medic, we use these religiously and base treatment off our readings. Per our protocol, adult <90% SpO2 = oxygen. Every set of vitals includes it. We use our monitor mostly but also have the portable machines like the Nellcor and I personally have one of the small pocket-size that I keep in my jump bag. 13 years in EMS, and that is a standard piece of equipment on every call. That said, I, as an overweight out of shape 46F found that I was having O2 sats during exertion in the 82 - 88% range and at night when sleeping as low as 79%. Every time I have a procedure involving sedation I am always harassed by RNs because I breathe too shallow and my SpO2 drops. In fact, after being treated with Nubain during a massive projectile vomit inducing migraine, they eventually 'narcanned' me so that they could discharge me. SpO2 82-85% - using a finger probe. Following hysterectomy...they had to apply oxygen during recovery because I was breathing too shallow, low SpO2, verified with finger probe. At any rate, I have been randomly checking my sats and have probably 20 pics I have taken of readings all below 88%. I sat 91-93% at rest. Yesterday I finally got in for an appointment with my PCP who almost instantly discounted that any of the readings were correct except the readings I obtained at night showing 79%. She basically just said you didn't get a good waveform with finger probes. She said she didn't doubt that I'd drop that low at night because of sleep apnea. My question is this. How can a person discount the accuracy of all these other readings but pick one or two as being legitimate? My boss, also a medic with probably 18 years experience had no clue and he text one of our medical team docs and he had no clue. I cannot find anything verifying this during a google search. I also mentioned to my doc that I understand 'chubby' people tend to run low and she outright said that wasn't true. Yet, again a simple google search brings up plenty of articles on obesity hypoventilation syndrome. Does anyone have insight on this? I'm a small town rural medic with very few ALS con. ed opportunities, so I fully understand that I am not the best educated medic out there but I just can't comprehend the inconsistencies. (I also make sure that I'm waiting for a good pulse grab on the probe before accepting the reading as legit). I would appreciate any th

not looking for finger or toe sensors
Hi, I would like some information on how to find medical grade or sensors that are used in FDA approved SpO2/pulse oximetry equipment. I searched digikey but they list sensors that are used in smartphones and health bands. I might not be searching in the right way. Can anyone point me in the right direction? Thanks!
