A stethoscope is required for auscultation. Manual meters are best used by trained practitioners, and,
while it is possible to obtain a basic reading through palpation alone, this yields only the systolic pressure.
Mercury sphygmomanometers are considered the gold standard. They indicate pressure with a column of mercury, which
does not require recalibration.Because of their accuracy, they are often used in clinical trials of drugs and in
clinical evaluations of high-risk patients, including pregnant women. A frequently used wall mounted mercury
sphygmomanometer is also known as a Baumanometer®.
Aneroid sphygmomanometers (mechanical types with a dial) are in common use; they may require calibration checks,
unlike mercury manometers. Aneroid sphygmomanometers are considered safer than mercury sphygmomanometers,
although inexpensive ones are less accurate.A major cause of departure from calibration is mechanical jarring.
Aneroids mounted on walls or stands are not susceptible to this particular problem.
