Interesting...thanks for posting.
I use an Omron bicep cuff at home and an Omron portable wrist cuff when I’m out. I.usually take three measurements ten minutes apart and get readings 10% to 15% apart. I’ve also calibrated the portable cuff to the upper arm cuff and find the portable consistently differs from the upper arm cuff by 6%. Given there variations I wonder how I would. Ali rate this new device to a cuff instrument.
It sounds promising, but I wonder about accuracy.
I have the wrist cuff too. It sucks so bad I quit using it. Plus it eats batteries like crazy................
“...how I would calibrate this new device”
Damn lousy auto-correct. Hopefully AI does something useful like ending terrible corrections.
It sounds like this device requires re-defining blood pressure. Systolic is the cuff pressure required to stop blood flow in a particular vessel. Duastolic is the cuff pressure when releasing pressure that blood starts to flow again. If this little cutie doesn’t actually stop flow then it’s measuring something else.
And normal muscle tension effects the “stop flow” part of the formula. One of my units is an Omron that can take three consecutive readings then either average them or give the last one. In my case it takes the first two cycles to soften up the muscles enough to create a meaningful reading. Not quite seeing how shooting a beam thru my arm would do more than give me a tan line?
