ABOUT “BLOOD PRESSURE”
English |
| What is blood pressure? |
| The heart is a pump that circulates blood throughout your body. Blood is pumped | |
|
| |
|
| from the heart at a constant pressure into arteries. This pressure is called the |
|
| arterial blood pressure and represents, in general terms, your blood pressure. Blood |
|
| pressure is indicated by several kinds of pressures, including the systolic pressure |
|
| that occurs when the heart pumps blood, and the diastolic pressure that occurs |
|
| |
|
| when blood returns to the heart. |
BLOOD PRESSURE Q&A
Q Why is the blood pressure measured at home different from that measured by the
physician or at a hospital? | English | |
A Your blood pressure may vary due to exercise, the ambient temperature or your | ||
mental state. When you have a physician or nurse measure your blood pressure, the | ||
| ||
pressure value is likely to be 10 to 20 mmHg higher than usual due to anxiety and/ |
| |
or stress. Knowing what affects your blood pressure helps you to better monitor your |

Q Why does the blood pressure obtained vary with measurement? | ||
A Our blood pressure is adjusted by automatic nerve function. Blood pressure differs | ||
with every heart beat. We are likely to think that our blood pressure is constant, but |
| |
it varies if you take measurements in repetition. Blood pressure is susceptible to the | Português | |
time of day, such as morning and afternoon, season and atmospheric temperature. | ||
In addition, blood pressure is easily affected by mental stress or emotional ups and | ||
downs. It tends to increase when you feel tension or decrease when you are relaxed. | ||
Q What is the benefit of measuring my blood pressure at home? | ||
A Blood pressure measurements taken at home give reliable data as they can be | ||
| ||
taken when you are in a stable and relaxed condition. Physicians place considerable |
| |
importance on blood pressure measurements taken at home. You should measure |
|
Your blood pressure changes all the time.
Your blood pressure differs according to your age, gender and a range of other factors. It is likely to be affected by your biorhythm during the day and by your posture, physical activities, mental activities, level of stress and even by the air temperature. The blood pressure of a healthy person generally varies within a day.
