Blood pressure is the blood pressure that circulates in the arteries. Also, the doctor usually takes the blood pressure to see if the blood pressure is normal, too high or not high enough. But does that mean auoi?
You probably have many questions about blood pressure:
- Is my blood pressure normal?
- "14/9" of tension, what does it mean?
- How do I know if I have high blood pressure?
- How to regulate my daily tension?
Discover all the answers to these questions in our special dedicated to blood pressure!
Before knowing if the blood pressure is normal or too high, you need to know how to measure blood pressure correctly and how to read the results of this measurement.
Blood pressure is the force of the blood flowing through the arteries. It is measured in two stages using a tensiometer, and therefore has two figures which are indicated either in mm of mercury (mm Hg) or in centimeters of mercury (cm Hg).
These two figures correspond to Systolic Blood Pressure (PAS) and Diastolic Blood Pressure (DBP):
- Systolic (or maximal) blood pressure is measured when the heart contracts. The blood is ejected from the heart and the pressure exerted on the walls of the arteries is stronger.
- Diastolic blood pressure (or minima) is measured when the heart relaxes.
The figures indicated by the doctor are generally in cm Hg: it indicates for example 14/9, 14 corresponding to the PAS: and 9 corresponding to the PAD. The doctor gives the patient less accurate numbers than those in mm Hg because they are rounded.You want to react, to give your testimony or to ask a question?
