What is the difference between sphygmomanometer and the electronic one?

Answer 1

A sphygmomanometer measures blood pressure. It can be electronic or manual; the main difference being how much human interaction is required to measure blood pressure. With a manual sphygmomanometer, you observe the amount of pressure in the cuff in real-time (usually on a dial gauge) while listening for a bruit in an artery distal to the cuff. An electronic sphygmomanometer does the same thing, but it electronically listens for the bruit and generally displays the blood pressure reading after the measurement is completed. So with a manual sphygmo someone must watch a pressure gauge and listen for a bruit to be heard and when it stops to get a reading. An electronic sphygmo does all this automatically and gives a reading. An electronic sphygmo is more convenient and doesn't require as much training to use.

Answer 2

A sphygmomanometer is a manual device used to measure blood pressure by inflating a cuff and listening to the pulse with a stethoscope. An electronic blood pressure monitor is an automated device that typically uses a sensor to detect blood flow and provides a digital reading of blood pressure. The main difference is in how the blood pressure is measured - manually with a sphygmomanometer, and electronically with an electronic blood pressure monitor.
