Guest guest Posted February 15, 2008 Report Share Posted February 15, 2008 The Mercury Sphigs should not ever need calibration, since they are actually measuring millimeters of mercury. They are the “gold (er, mercury)” standard. Though I no longer use them, one observation I have made over the years is that if you walk into a room with a mercury sphig that has a youngster in it, and you see mercury on the floor, there is a high probability that the youngster has ADD. I have noticed this correlation about 4 times in the 25 years I practiced in a conventional practice, when patients had to wait in the exam room for the doctor to come in and see them. Having just one exam room makes life much easier. dts From: [mailto: ] On Behalf Of Sent: Thursday, February 14, 2008 9:14 PM To: Subject: Re: aneroid sphygmomanometer calibration The springs break. I would not think the mercury ones need calibration. During my training, we only used mercury ones. Being here in california with our earthquakes, better to avoid mercury. Bp machines are not that expensive. when the warranty runs out, I guess it would be time to replace it. There's a calibration circle for zeroing on the aneroid dial. Just like zeroing a scale Matt in Western Pa aneroid sphygmomanometer calibration have it checked with your yearly periodic equipment maintenance. in between periodic maintenance, if you have one which obviously doesn't work, don't use it; i also look for congruency between any individual reading and the patient's condition and history, and previous bp measurements. hope that's helpful.

They are very accurate and are the gold standard to which other sphygo...s are calibrated to as far as I know. I do have my mercury spill kit, though. I got pretty good at cleaning up mercury when I was using a mercury thermometer to check my basal body temps way back in the dark ages when I was trying get pregnant. I kept sending them sailing across the room when shaking them down first thing in the morning. But then maybe that explains this memory problem that keeps getting worse. What was I talking about anyway?

Guest guest Posted February 15, 2008 Report Share Posted February 15, 2008 For those space cadets among us, the mercury sphyg can't be used as it requires normal earth gravity. " The millimeter of mercury (symbol: mmHg) is defined as the pressure exerted at the base of a column of fluid exactly 1 mm high, when the density of the fluid is exactly 13.5951 g/cm³, at a place where the acceleration of gravity is exactly 9.80665 m/s² " On Sat, Feb 16, 2008 at 6:31 AM, T. , MD wrote: > > > > > > > > > > The Mercury Sphigs should not ever need calibration, since they are actually > measuring millimeters of mercury.
