O2 saturation and chemo

[spencoid2]

I finish my last does of paxlovis and starting to feel just slightly human. I thought the 4th dose of doxytaxel was horrible but it seems it is largely due to the covid.

I ended up spending the whole day in the ER (with travel) for no reason. I has having widely fluctuating O2% and pulse

I don't remember any of this before chemo and covid. Doxytaxel messes with blook counds. Does this change or a change or greater variation in cell color screw up the cheap oxy pulse meters.

Is there as better one you can buy short of an EKG machine

Apple Watch has EKG and O2 sensors

I am a bit biases, I do not like apple. Their promoting of their watch as an EKG should be stopped by the FDA or ??? An EKG is a rather complicated machine that uses sensitive electrodes on a minimum of locations. What they do is interpret pulse waves nothing more and if they say they can provide as much data as EKG with pulse wave analysis, wither they are far advanced of any other technology or are full of it.

O2 is quite easy to measure but is also to interpretation. A white light is shown on the finger (or earlobe etc) and is either transmitted or reflected to sensor. The "degree of redness" correlates to the level of saturation. I do not know the details (at all ) of the computational methods used but would guess that it is not trivial and that medical equipment manufacturers who have been these things for many years might just have some better methods than those used by the makers of the $20 type

There are a few commercial models on ebay and i have some questions to the sellers who probably know nothing. Especially if returnable (which one is) not a big risk of $99 or so.

If anyone has information (not pages) of actual information on how saturation is gotten from skin color and especially whether better units have better firmware and can deal with low blood counts. My pulseoxi said my pulse was as low as 30 one second and then 150 the next. It is now fine. So I think it was some strange blood color (maybe my blood is gay and is parading rainbow flags messing up the sensors) I guess my blood is as gay as I am but I generally do not wave rainbow flags around, prefer the more subtle approach.

AliveCor KardiaMobile ECG Moniteur | $89 from Amazon

i found a few of that brand but so far nothing with O2 saturation. Do you have one that does that too. Not knowing any details, I sort of favor the two electrodes thaat span your chest by using opposite hands. I think this can do a better "ECG" than the Apple watch

On Amazon at $50.00 = ranya S2 Smart Watch with All Day Heart Rate Blood Oxygen Sleep Monitor, 3ATM Waterproof Fitness Tracker, 25 Sports Modes Smartwatch for Android and iOS Phones, Sport Watch for Men Women Black.

It is like a BETTER Apple watch but not with electrode like the other one .

But more expensive.

If you can afford it, IMHO I think that is the best for the price.

Hope this informations are helping you.

I have an unlimited budget (well maybe $1000000) for tools but as cool as this looks i do not need the EKG, what i really want is a blood saturation meter that works with fucked up chemo blood

What I personnaly used since many years (I have COPD(Pulmonary Emphesyma Grade Gold 3), is the Lookee Sleep Ring.

It records for 10 hours and vibrates when the O2 Sat gets below the limit that you choose. Mine is set up at 85%. BTW last weeks I got awaked by a very strong vibration and discovered that my sat whent down to 66%. My fingers nails were blue and I sit up and took big deep breaths and the sat went back to 86%.

There is a computer program that show you 2 graphs (O2 sat + Heart Rate)
