That the blood pressure measuring device is called sphygmomanometer
is known to almost everyone but only few people (those unfortunately frequent
the hospital) know that the BP measuring gadget has changed over the years.
The most commonly used in hospitals is welch
allyn sphygmomanometer that is known for its accuracy. Since it comes
with a 2 year replacement warranty, it is the most preferred one by big
hospitals that is always fully packed.
Individual doctors who maintain a personal hi-tech clinic in posh
localities use expensive sphygmomanometer that gives consistent readings
with digital display.
My husband’s BP is always normal but still he has to undergo the
diagnostic procedure more often than me with a chronic low BP score.
What a contrast!
