I must agree with Scott and let kpa be phased in as instruments are
replaced. Expecting someone (even a trained individual) to read a conversion
chart during disaster triage is only going to result in both deadly mistakes
loss of time.

I think I¹m 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 ³field train² 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.
