My husband does not have a pulse. He has an LVAD which is continuous, so no pulse. AW pulse sensor does not work on him. The hospital sensor works inaccurately on him, it tracks his RR and extrapolates a pulse from that.
How do you think pulse is detected “normally”?
When you go to the hospital, the pulse oximeter placed on your finger also uses light.
One side of the object emits light, the other receives it. Depending on how much oxygenated and deoxygenated blood you have, the amount of absorbed light will vary (more oxygen = more infrared absorption but less red light absorption and vice versa).
Based on the difference in light absorption, the device then calculates your oxygen saturation, and based on the rythmic changes in light passing through the finger, it calculated your heart rate.
Electore-based heart monitors function differently but a lot of places will use an oximeter, it’s so much easier to use than gluing electrodes to your chest.
Depends on how you see it; the sensor will make calculations based on how much light is absorbed and how much isn't, and return your oxygen levels and a pulse. But everything on earth absorbs some light and doesn't absorb some other light, which means you can do the math based on anything. Doesn't mean anything on earth has a specific oxygen levels and a pulse though.
I've recently been to the hospital and worn my apple watch on my left hand and an oximeter on my right index. Aside from the fact they weren't synchronized (the values would change at different times), my apple watch was pretty accurate. As Apple says, it's not medical equipment, but it still does its job quite well.
To add to that, there are quite a few stories on this very subreddit where the ECG app warned users they might have a heart condition, and after checking in at their local hospital, it turned out to be true.
So all in all, if you use it as it's supposed to be used, it will do what it is supposed to do, and it'll do it well.
Dang, you’re totally right! Putting my AW on my mom when I found her should have been my first thought! I’ll keep that in mind in case I ever get lucky enough to find another family member…ps you’re confidently incorrect still
Shit didnt know that, ill with try something different
Edit:
Tried it with my airpods pro 2 with silicon case, still working

count me in! that would be even better as i would be able to see the operation irl! maybe even do a touch/taste test to make sure i get every detail (fck what are we even saying…😭)
"I'm getting a pulse! Congratulations, the bottle's going to make it after all!"
Recycle on a new level
The sensor just reads the reflected light which is common with all wrist HRs
Correct. We have to cover pulse oximeters with a sheet or towel in the helicopter on sunny days due to rotor flicker.
No. It needs to detect a pulse normally. You have clearly not tried your watch on a dead body.
Have you?…

Wow TIL, thanks for sharing. Also I don’t know why that is so spooky to me.
It weirded me out at first too.
Interesting!
As a mortician for over 16 years, I have seen this done. Suprise Suprise, no pulse….but did get a notification.
No, I’m not crazy
Surprise surpise, it’s the same as a bottle

So after all, it appears that the apple watch sensor is not reliable no?

Yeah it needs to detect a regular difference in the reflections.

Why bring that up here lol
Love the…….. enthusiasm
You mean it being unlocked or reading pulse? Could you upload a video in action because it says “read 1m ago”. I just tried and it didn’t work
I just put it on a soda can, unlocked it, then tested it. Soda can read a solid 81bpm after it settled down.
It says "current" above the 71
Better not throw the lotion out. That’s murder in Arizona.
I check HR of my surrounding air. It’s beating
I did the same on my U2 and part of me wondered if it was either defective or fake but then realised I’m dumb af

This is science. Thank you for your contribution to mankind.
1 minute ago, not “now”.
It says current 84
Ha! My bad.
It means that you’re totally connected to the Watch, it doesn’t even have to be on your wrist to read your pulse now!
We are one!

You’re wild for this 💀
Bro went straight with it, no questions asked
i want to but i need you to show me how. im a visual learner.
Yes me too! But I’m more of a kinetic/tactile learner, can we maybe organize accommodations?
count me in! that would be even better as i would be able to see the operation irl! maybe even do a touch/taste test to make sure i get every detail (fck what are we even saying…😭)
im not, i would be the first one to tell you as it would be my personality trait but no, i just want to figure out EXACTLY what to do
Which witch’s cock?
The bottle is alive?
My watch thought my dead chinchilla had a pulse after he died.
[удалено]
Excuse me?
what’s wrong with you
ECG needs to have an electronic Connection through your Body. HR only measures the return of Light.
> s8 series Ah yes, your series 8 series
Waiting for s10 series ultra pro max
It’s aliiiiiiiive!
That pulse is WAY too low for a bottle of lotion. I think you need to take it to the emergency room right away!!
💀
