Blood pressure is a fundamental type of blood pressure to circulate the blood through the blood vessels and supply oxygen and nutrients to all organs of the body, and thus, can function. By definition would be the pressure exerted by blood against artery walls.
- arterial pressure
This blood pressure or blood pressure is determined by the strength and volume of blood pumped and the size and flexibility of the arteries. Must be taken into account when measuring blood pressure it can vary depending on the level of activity, temperature, diet, emotional state, posture, physical state and even the drugs you are taking. The blood pressure measurement can be made at any time of day, and always will be with the arm supported and held at heart level.
Blood pressure is divided into
- Systolic blood pressure: which is the maximum systolic blood pressure (when the heart contracts). Concerning the effect of pressure exerted by blood ejected from the heart on the vessel wall.
- Diastolic blood pressure, corresponds to the minimum value of blood pressure when the heart is in diastole and between heartbeats.
Blood pressure is measured in millimeters of mercury (mmHg). The normal blood pressure values vary between 90/60 and 120/80 mmHg, the latter being the ideal value. If the values are higher than 130/90 mm would be talking about hypertension or high blood pressure of 90/60 and below are indicative of hypotension.
It is important to check blood pressure to know what is in the correct values. Sometimes the doctor will repeat the test, since a single high measurement does not necessarily mean that they suffer from hypertension and a single normal measurement does not necessarily mean suffering.
Abnormal values in blood pressure may be caused by several factors:
- Cardiovascular
- Neurological disorders
- Renal and urological disorders
- Pre-eclampsia in pregnant women
- Stress, anger or fear
- Drugs
- Anxiety
