What does a sphygmomanometer measure?

A sphygmomanometer is a device that measures blood pressure. It is composed 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. 

 In 1881, von Basch created the sphygmomanometer and the first non-invasive BP measurements. However, in 1896, Scipione Riva-Rocci developed further the mercury sphygmomanometer, almost as we know it today. 

The sphygmomanometer could only be used to determine the systolic BP Digital sphygmomanometers are automated, providing blood pressure reading without needing someone to operate the cuff or listen to the blood flow sounds.

 

However, digital types need to be more accurate. In some situations, some healthcare providers use digital sphygmomanometers for screening and manual ones to validate readings.
