Name the types of sphygmomanometer.

Explanation

1. Manual sphygmomanometer
a. Mercury sphygmomanometer:
It shows blood pressure by affecting the height of a column of mercury which does not require calibration.
b. Aneuroid sphygmomanometer:
It is a mechanical type with a dial and it requires calibration checks unlike mercury manometer.
2. Digital sphygmomanometer:
It detects systolic and diastolic pressures by an oscillometric detector. It is easy to use even without training.
The maximum pressure exerted during the ventricular contraction is called systolic pressure and the minimum pressure exerted during the ventricular relaxation is called diastolic pressure.\
