blood pressure range by age is one of the main parameters or indicators to be aware of the state of our health, and also is to know if the values of blood pressure are within normal limits, according to our age.
It is not at all difficult at the moment in which the means and devices of diagnosis abound, including applications for the cellular telephone.
In this article we share elementary information about blood pressure, the meaning of some medical terms and normal levels according to age, trying to explain everything in a popular and understandable language.
What is and what indicates blood pressure?
Blood pressure (BP) is the pressure exerted by the blood pumped by the heart, against the wall of the arteries.
Its value is usually expressed in millimeters of mercury (mmHg).
Systolic and diastolic blood pressure (minimum and maximum)
There are two components of blood pressure, the systolic or maximum and the diastolic or minimum, both depend on the heart rate.
The systolic pressure is the one registered at the moment when the heart contracts (systole) and increases the pressure of the blood in the arterial walls at its maximum period.
The diastolic is the one registered when the heart relaxes (diastole), and decreases the pressure to its minimum point.
The level of the two parameters in a person is important and should be cause for concern.
The increase above normal levels of systolic or diastolic blood pressure is known as hypertension or high blood pressure.
It is also responsible for other serious problems, such as chronic kidney failure, aneurysms and lesions in the ocular blood vessels.
It is important to know that hypertension is a silent disease, in its first stages.
The decrease below normal blood pressure levels is known as hypotension or low blood pressure.
To indicate a person’s blood pressure, two values are used separated by a slash, where the first corresponds to the diastolic pressure (minimum) and the second to the systolic (maximum), for example: 80/120.
Normal values of blood pressure
The blood pressure values considered as normal depend a lot on the age range, because over the years the blood vessels lose their elasticity and the tension rises.
It also varies according to sex and height.
There are also situations that affect blood pressure momentarily such as stress, anxiety, other emotional problems and the consumption of some medications.
Also other factors such as inadequate diet, excessive consumption of salt and caffeine (coffee or cola), sedentary lifestyle, smoking, excessive consumption of alcohol, birth control pills, genetic predisposition, family history and overweight or obesity. There are several tables that order blood pressure values by age with small intervals, but in practice it has been shown that none of this is accurate.
The consensus currently among specialists is to use a more flexible and simple parameter scale, in which age is not considered in such a detailed way.
People are divided into four groups: healthy adults (including adolescents), hypertensive or drug-using adults, seniors (over 60) and the elderly and finally children.
Blood pressure values for healthy adults
• Prehypertension – The maximum (systolic) pressure should be between 120 and 139 or the minimum (diastolic) between 80 and 89 mmHg.
• Hypertension Phase 1 – The maximum pressure should be between 140 and 159 or the minimum between 90 and 99 mmHg.
• Hypertension Phase 2 – The maximum pressure should be between 160 and 179 or the minimum between 100 and 109 mmHg.
• Hypertensive crisis – The pressure must be above 180/110 mmHg.
Blood pressure values for adults who use medications
Blood pressure values for the elderly and the elderly
• Adults over 60 who have diabetes and / or chronic kidney disease – The pressure should not exceed 140/90 mmHg.
Blood pressure values in children
The height percentile is the statistical variation of a child’s height, compared to others of the same age.
how is the arterial pressure measured?
Blood pressure can be known in several ways:
1 – Using the traditional method, using two devices: a stethoscope (allows to hear the sounds of blood flow in the arteries) and a sphygmomanometer (inflatable cuff and a manometer, also known as aneroid) .
The bracelet, usually around the upper arm, is inflated to approximately 200 mmHg, at which point no pulse should be heard, because the brachial artery is completely blocked.
The heartbeats begin to be heard at the point that indicates the systole and are no longer heard at the point of diastole.
You can also notice small jumps in the gauge needle when descending, between the two levels.
3- Using more recent alternate methods, such as mobile applications on a cell phone that has a camera and flash.
