Describe how blood pressure is measured using a sphygmomanometer

A sphygmomanometer is a devices which is use to measure blood pressure. Sphygmomanometer is consist of rubber cuff (inflated) which is use to wrap around the arm and the dveice measures the pressure generated in the cuff.

Heart beats allows the blood to flow in the arteries and causes rise in the pressure, called systolic pressure and after thhis when pressure decreases, pressure is called the diastolic pressure.

The sphygmomanometer cuff get inflated with the systolic pressure and when valves are open the cuff releases the pressure. When cuff pressure become equal to systolic pressure, it creates blood flow turbulence and the sound can b emeasures by stethoscope. these sounds are notived and cuff pressure is meausred. The blood flow turbulence will be created till the pressure of cuff reaches below the diastolic pressure. When the blood flow sound stops, it indicates the begining of diastolic pressure.

So, this is how a sphygmomanometer measures blood pressure.
