V - How to measure high blood pressure?

Principles
5.1 - The most reliable method: to place a probe measuring the pressure directly in the artery
5.2 - The most useful method: The measure of the blood pressure using a sphygmomanometer with a cuff
Measurement of the blood pressure
5.3 - At rest at the doctors
5.4 - At rest at home, using a self-measurement device

5.5 - During a physical exercise
5.6 - Measurement by an ambulatory monitoring of the blood pressure during 24 hours
Description of the device
5.7 - The cuff
5.8 - Method for the measurement of the blood pressure
5.9 - The sphygmomanometer


5.1 - The most reliable method: to place a probe measuring the pressure directly in the artery

Indeed, the most reliable but aggressive method consists in placing an arterial pressure probe directly into the artery... This technique is sometimes carried out during an exceptional cardiological examination (like a coronarography, a catheterization), but this method is not used in current practice.

Recording of the blood pressure using a probe introduced into the aorta: first historical method of measurement of blood pressure (1732, Stephen Hales).

Nevertheless, there are two exceptions: sometimes, when the blood pressure is very high and the patient does not complain about anything, the diagnosis of calcification of the arteries can be suspected. In this case, the blood pressure measured with a arm band (or cuff) is abnormally raised and must be evaluated by the introduction in the artery of a pressure probe.

The patients treated in an intensive care unit who require a permanent monitoring of their blood pressure represent the second exceptional case. A pressure probe is thus introduced in the artery of the wrist or in the artery of the thigh.
