It is necessary for adults to know translating their "medical examination numbers" to maintain some necessary measurements and keep them within certain criteria, so what about blood pressure?

Regarding blood pressure, guidelines issued by the American Heart Association and the American College of Cardiology recommend that everyone - regardless of age - should seek blood pressure below 130/80 mm Hg, according to a report in the Washington Post.

The heart pumps blood around the body. As it moves, flowing blood creates strength and pressure on the walls of blood vessels called "blood pressure." During his work, the heart - which is a muscle - contracts and relaxes, and this leads to blood pressure having two values, the first is called systolic blood pressure and is recorded when the heart contracts, and the second is diastolic pressure and is recorded when the heart muscle relaxes (relaxes).

Blood pressure is measured using a special device that may be manually such as a mercury pressure meter, or automatically like an electronic pressure gauge. While the first may be more accurate, the second is easier to use.

The device records two readings, the first - the highest - representing systolic blood pressure, and the second - the lowest - representing diastolic. The reading is written in the form of a fraction, the numerator is systolic and the denominator is diastolic. For example, if the systolic pressure is 115 and the diastolic is 75, then this person's blood pressure is written as 115/75.

The unit of measurement is the mercury millimeter, which means that the systolic pressure, for example, is equal to the height of a mercury column of 115 millimeters in length.

The American Heart Association classifies blood pressure readings according to the following:

  • Normal blood pressure: systolic less than 120, and diastolic less than 80.

  • Pre-morbid: systolic between 120 and 139, and diastolic between 80 and 89.

  • High blood pressure in the first stage: systolic 140-159, and diastolic 90-99.

  • Second stage hypertension: Systolic 160 or higher, and diastolic 100 or higher.

For those over 65 years old, if he suffers from chronic diseases, such as lung disease, type 2 diabetes or dementia, then very high blood pressure may lead to risks such as feeling dizzy and falling.

And what must be done for many elderly people is to maintain levels below 150/90, because what is higher than that requires blood pressure medications, says the doctor.

The head of the Cleveland Clinic cardiology department, Stephen Nissen, says that he who is healthy should have a pressure of 80/80 or less. To get there, he should - instead of using medications - first think about focusing on lifestyle changes, such as Lack of extra pounds, eating a healthy diet, maintaining a ratio of less than 1500 milligrams of salt per day, and exercising for at least ninety minutes a week.
