Title: Re: [USMA:35647] Re: blood pressure kPa

Scott,
I tend to agree with you - if the world-wide
medical profession agree on a particular system on units, then they should
be left as they are and as long as there is very little contact with the Chinese
and Russian medical profession, then the cost of the changeover could cost too
many lives to make it worth-while.
I remember readign a few years ago of an emergency
operation that was carried our on a British Airways flight from Hong Kong to
London. The operation was performed in a make-shift theatre by two doctors
who had never met each before the flight. They had to communicate and it
was essential that they used the same language.

kPa
I think Im about to commit SI heresy here but I am
in favor of keeping blood pressure being reported in mm Hg for a simple
reason: disaster planning. Although it is a laudable goal to have pressure
reported in actual units of pressure, I think that planning for emergencies is
a compelling reason to report indirect measurement reading without
conversion.
Raw data from various electronic monitoring equipment is
converted to display some output (whether in mm Hg or kPa). The raw data will
look different, depending on the material and calibration of the load cell
used to take the measurement. However, when the power goes out for an extended
period of time (such as after a hurricane, earthquake, tsunami et cetera),
hospitals and doctors have to pull the old low-tech manual equipment out and
take measurements in mm Hg. In an emergency, a doctor/emergency responder may
have to field train whoever is available, to assist in processing
casualties. This person may not have the math skills necessary to properly
convert units but they can be easily trained to take a direct reading of mm
Hg off the gauge.

So did the Russians
(the Soviet Union, that is) some 30 years ago. Whether
the Russians and
all the break-away republics continue the practice today, I
do not
know.
