I've been thinking a lot about continuos health parameter monitoring lately. For the last 100 days or so I have been running a personal health experiment and collecting multiple data points during the process. I guess some use the term "bio-hacking", not sure if it applies. The experiment has included multiple fasting periods, with a maximum of 7 days as well as changing one variable at a time in categories such as d…

> how many people might be misdiagnosed and put on medication every year because of bad data Another variable that causes this is the patient. They don't like the medication or don't take it properly but tell their prescriber that they are taking the medication correctly (age, culture, dementia etc). The prescriber then adjusts the dose.

Very true. My wife is a doctor. This is one of the issues that comes out most frequently during conversations about healthcare.

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!

My RHR is around 35. The rare occasions I get to go on vacation it dips into the high 20s while I'm sleeping. I haven't been on a real vacation in 2 years, though :/

So basically resonance frequency of an artery doesn't depend on the artery's radius or wall thickness?

Or perhaps is that enough the case on a certain lower frequency band, where variations in those quantities are much smaller than the wavelength?

I find doctors and nurses rush things too much in general. I guess they're paid flat-rate, like mechanics?

there's just no time. we have to write down everything you tell us, we have to come off genial, make you sure you aren't lying about something or mistaken, and fix you.

Thank you.

> The new patented technique, called resonance sonomanometry, uses sound waves to gently stimulate resonance in an artery and then uses ultrasound imaging to measure the artery's resonance frequency, arriving at a true measurement of blood pressure.

That's invasive - gently or not.

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.

You are supposed to be calm and relaxed for a proper blood pressure reading. Doctors have to find the resting baseline to diagnose hypertension.

> That's why the most appropriate way nowadays is to measure it at home, and keep a BP log. "Oh yea those machines are junk and totally wrong" And/or "WHY DO YOU TAKE YOUR OWN BLOOD PRESSURE?!" followed by accusations of being a hypochondriac. Also the log is junk because I don't know how to properly take the blood pressure. Unlike the assistant who is also doing it wrong. lolololol

my blood pressure is significantly higher at the doctors office than home. I measure my blood pressure each morning at home. My doctor is happy to accept those readings.
