What is the procedure to determine blood pressure in clinical practice?

The blood pressure is determined in the brachial artery with a sphygmomanometer.
The cuff is placed around the arm, over the brachial artery, and inflated until the pressure in the cuff is greater than the pressure in the artery.
At this moment, the brachial artery is completely occluded, without flow, and no noise is heard with the stethoscope on the artery or the pulse is felt in the radial artery.
By progressively deflating the cuff, the entry of flow into the artery is allowed, but as it is partially compressed, the flow is turbulent and this generates an audible noise that corresponds to the value of the systolic pressure.
When the pressure of the cuff is reduced even more, the noise suddenly fades away as the turbulence disappears. At this point, the value of the diastolic pressure can be determined.
