an introduction
High blood pressure is one of the most common diseases and is considered a serious disease called the silent killer, or “silent killer.” Blood pressure is the force of blood pressure in the walls of the blood vessels as a result of pumping from the heart.
Types of blood pressure
There are two types of blood pressure:
- Systolic blood pressure is the pressure produced by the force of the heart pumping.
- Diastolic blood pressure is the pressure resulting from the expansion of blood vessels after contraction as a result of pumping the heart and always read the pressure of the systolic is higher than reading the pressure of the diastolic.
Blood pressure reading
Blood pressure is read through the setting of the systolic pressure on the diastolic pressure. Through this reading, the patient’s condition is determined whether his blood pressure is normal or he suffers from high blood pressure.
Reading blood pressure 115/75 mmHg is the natural reading in the right people and classifies the person by reading blood pressure in one of the following categories:
If the reading of the systolic pressure below 120 and diastolic below 80 is considered to be within the normal level of blood pressure.
If reading the systolic pressure from 120 to 139 or reading the diastolic pressure of 80-89 is considered the person in the pre-patients stage.
If reading systolic pressure of 140-159 or reading diastolic pressure from 90-99 is considered a person with a first stage of high blood pressure.
If reading the systolic pressure 160 or above or reading diastolic pressure 100 or above is considered a person with a second stage of high blood pressure.
Blood pressure reading is different. There is blood pressure measured at home and another is measured in the clinic. Sometimes a special patient is placed throughout the day, which measures blood pressure every 30 minutes and obtain a more accurate knowledge of blood pressure.
How to measure blood pressure
Blood pressure is measured by different devices:
- Mercury Blood Pressure Device.
- Digital Blood Pressure Monitor.
Causes of high blood pressure
Blood pressure disease is categorized as a result of the reasons for its rise to:
- Primary blood pressure: 90% of blood pressure diseases are of this type.
- Secondary blood pressure: 10% of hypertension is called secondary because it occurs due to known causes, most of which are related to kidney disease or side effects of certain drugs.
