We might get rid of the SQUEEZY BP machines

Remember this one?
March of progress!
It's ever so trendy now for the doctor's assistant who "rooms" you to slap on an automatic blood pressure cuff that then, in my experience, squeezes your arm until you scream for mercy and goes down just as slowly. Often, the reading is inconclusive.

Can you tell? I hate these! I often insist on my BP being taken with the manual soft cuff and by a non-sadist.

Now, researchers at the Jerusalem College of Technology and the Shaare Zedek Medical Center have developed a better way to take systolic blood pressure.

Systolic is the top number, diastolic the bottom one. The customary manual or automatic methods can be affected by "white coat syndrome"--the tendency of being the doctor's office creating a higher reading.

Sometimes patients are asked to take their pressure at home to avoid the white coat effect.

Still, the automatic is less accurate than the manual.

An incorrect high reading can lead to the prescribing of meds the patient does not need and which might be harmful.

This team therefore developed a new device using a pressure cuff on the arm and an electro-optic device on the finger. Similar to that finger clamp that measures oxygenation, the finger device sends light through the finger and picks up the pulses of the heart rate.

At the same time, the cuff is inflated. When the cuff pressure increases above systolic blood pressure, the pulses disappear. When the cuff pressure goes below the person's systolic, the pulses reappear.

Anyhow--it works. How soon can we see it in use? Who knows? And will the cuff part be so alarmingly tight?

Maybe it could use some more work...but stay tuned.

Of course, there are many variations on sale now...lower arm cuffs, finger alone, on your phone, etc.
