How the blood pressure is measured by ultrasonic method?

Ultrasound techniques

As the cuff is deflated, the movement of the arterial wall at systolic pressure causes a Doppler phase shift in the reflected ultrasound, and diastolic pressure is recorded as the point at which diminution of arterial motion occurs.

What is the oscillometric method of measuring blood pressure?

OSCILLOMETRY is a widely used approach for automatic cuff blood pressure (BP) measurement [1]–[3]. In this approach, a cuff placed on the upper arm is inflated and then deflated while the pressure inside the cuff is measured.
