Sphygmomanometer Definition. A sphygmomanometer is a device that measures blood pressure. It is composes of an inflatable rubber cuff, which is wrapped around the arm. A measuring device indicates the cuff's pressure. A bulb inflates the cuff and a valve releases pressure. A stethoscope is used to listen to arterial blood flow sounds.
As noted, the sphygmomanometer has become, if not the gold standard, at least the default option for blood pressure measurement, even though that method cannot in any sense be regarded as having final validity, that is in some ultimate sense of measuring real blood pressure.
