Huge deal for humans moving forward. ~5-8yrs too late for me (2-5yrs for product dev, 3yrs since a hemorrhagic stroke that was likely caused by serious blood pressure).

I was 40 at the time and never measured my blood pressure (and certainly never when exercising). After the event I measured it all the time. During the 8th time of sitting in a chair, rolling up my sleeve, I thought, the Apple Watch has BP sensor, right?

That question sent me on a quest only to find that humans had not yet figured out a way to measure blood pressure on-the-go.

Congratulations on this effort!

As a person who had a hypertensive crisis late last year, nothing boils my blood (yes, a pun, I am fine now) more than how people measure blood pressure incorrectly in doctors offices and even hospitals. There are many different things than can increase a BP measurement above the "baseline" including talking, moving around, not having rested but also just waking up, not being in a supported position, only a single va…

I'm a resident physician and I deny having my BP taken in outpatient clinics. The techniques used are ridiculously inappropriate: "Ok, Mr. So-and-so, come with me." calls the nurse, as the pt who is irritated for having to wait 30 minutes quickly gets up to walk along unknown hallways, while rushing to finish a phone conversation, stressed and not knowing where to turn next..."Ok, now we're going to weigh you on this…

People try to cheat BP tests? Because they dont want tp taks BP meds? Daaaang I'm trying to get my head around that. I guess I'm missing something because that sounds like an incredibly tangled way to be.

Pilots (and astronauts) lie to their doctors to avoid being grounded.

One thing that I think would dramatically improve the routine screening numbers at doctors' offices would be to try and take it after the patient has been sitting down for a few minutes waiting for the doctor after the other vitals have been taken. If I'm going to sit around for 15m+ anyways, why not use some of that time to let BP stabilize?

I had hypertension for about 15 years and after quitting drinking and smoking no longer do. I still suffer from white cost hypertension regularly and frequently have to tell nurses to just press the button again - second time drops back to normal range with a drop of about 20/10.

I had it too. When I was under stress, sometimes I could hear my pulse in my ears like a whooshing sound. I stopped drinking and my BP is now completely normal, and RHR is low 40's. Sleep is much better too.

Are you serious? Your RHR is in the low 40s? Mine is typically 58-65 and I was told I have bradycardia!

There’s a company called Biobeat that sells a patch you put on your chest for continuous 24-hour blood pressure measurement [1]. From what I’ve heard it’s in clinical use and works.

This believe this blood pressure watch has been approved in a few European countries. It requires you to calibrate against the normal approach every month. I think they are trying to get it approved in the US by next year. https://aktiia.com/

I wonder how do you calibrate it in practice.
