Blood pressure is the blood pressure in the arteries. Essential step for any consultation, measuring the voltage, however, remains mysterious. What are the two numbers? When can we talk about high blood pressure? How does a blood pressure monitor? Doctissimo made the point on all of these issues that care you about.

In the body, arteries serve the lactating mothers. They lead the blood from the heart to the body’s different tissues, providing cells oxygen vital to their survival. At each contraction of the heart, the blood is expelled with strength of heart and powered cavities in these pipes. To perform their function in a satisfactory manner, they must remain flexible and not clogged (fat free).

The secrets of the voltage

Systolic and diastolic
The arrival of this blood wave exerts pressure on the walls of the artery, as would the water arriving in a garden hose. This contraction of the heart, or systole, pressure corresponds to the highest measured when taking voltage. This is the systolic blood pressure.

After systole occurs a phase of relaxation, or diastolic, in which the heart relaxes and fills. The pressure exerted by the blood on the artery walls is then lower. It corresponds to the lowest number, or diastolic blood pressure.

The art of the cuff
It is these pressures that are studied when taking voltage. Become the indispensable instrument of reference, the blood pressure monitor consists of a cuff with an inflatable cuff connected to a pressure gauge for measuring the pressure.

Placed around the arm and inflated, the cuff interrupts the passage of blood in the artery of the arm (brachial artery).

The doctor raises his stethoscope on the artery, below the cuff, that it gradually deflates.
When the cuff pressure exceeds the systolic blood pressure, the blood will not flow and no sound is audible. When the cuff pressure decreases, blood begins to pass into the artery and vibrates the walls, compressed by the camera. Each heartbeat results so a regular, synchronous with the pulse noise.
