82 is a bit below dangerous I'd say, especially if the wearer is unconscious.
If the wearer can see that value and understand it, it's probably a hardware failure.
That was my reasoning exactly.
The sensors are decent enough for something that cost less than 50 euro, but clearly there's room to improve.
Good contact is quite fickle if there are any obstructions or even dirt on the skin, but my experience are mostly with the fingertop or earlobe sensors which are quite sensitive due to only using a red led. Does the wrist one use another kind of tech?
It's more to do with me not keeping the wrist strap actually the tightest it would go, because it's annoyingly squeezing then.
Sometimes, on some angles, there will be a bit of space between the sensor and my skin which would explain the bad reading.
Pretty sure the tech is more or less the same tech as in the basic rubber thing that gets put on your finger at hospital. Except those alway used red imo, not green. But idk. I don't really need the SPO2 feature so I don't mind.
Thanks for indulging my curiosity :)
My pleasure.
Yes, I agree.
Which is why I only got one after being declined from a sleep clinic for absurd reasons.
Mine uses a green light, but afaik it's more or less the same as hospital ones. Just cheaper shit. Like how an aeroplane and a paperplane are technically both aircraft. You could study aerodynamics with paper aeroplanes, but it's gonna be much easier if you don't have to resort to that but can actually study the knowledge available to make reasonable choices.
the public healthcare here just plain up denied my referral from a psychiatrist. despite more than 20 years of sleep problems. if I could meet the person who made that decision, I'd have a few strongly selected words to tell them
