Normal Blood Pressure
What is Blood Pressure? ^
By measuring blood pressure it can be checked if an individual has hypertension (high blood pressure), normal tension (normal blood pressure), or hypotension (low blood pressure). It requires the use of sphygmomanometer and stethoscope (manual way of measuring) or by using electronic measuring devices. Hypertension (HTN) is defined as BP of 140/90 mmHg or higher.
Blood pressure is created by the force of blood pushing against the walls of blood vessels (arteries) as it is pumped by the heart.
It is recorded by two numbers, covering systolic and diastolic blood pressure. The upper number is the Systolic blood pressure which is the highest pressure in the blood vessels, which happens when the heart contracts or beats. The lower number is the diastolic blood pressure which is the lowest pressure in blood vessels in-between heartbeats when the heart muscle relaxes.
Doctors and other health personnel who are measuring the blood pressure will record the difference between the period of momentary rest (relaxation) and maximum work (contraction) of the heart. Systole refers to the maximum split-second of the heart which commonly occurs at the peak of the ventricular (lower chamber) contraction. On the other hand, the diastole refers to the maximum split-second of the heart when the atrium (upper chamber) fills blood to the ventricle during peak of cardiac relaxation.
What is normal Blood Pressure?
Normal levels of both systolic and diastolic blood pressure are particularly important for the efficient function of vital organs such as the heart, brain and kidney and for overall health and well being. The normal blood pressure varies according to the age and gender of an individual.
It means that the blood pressure of children is different from the adult. The same goes with gender preferences. Women may have different blood pressure reading to men. There are several factors which make these differences occur from one person to another. Moreover, the baseline data for checking the blood pressure may differ, as well. Blood pressure of pediatric clients has its own normal level. Adults and elder individuals have its normal levels. Nevertheless, any slight changes with the systole and diastole for several readings will help diagnose the condition of the person.
Normal Blood Pressure for Women ^
Generally, the normal blood pressure for adult woman is 120/80 mmHg. However, there are several factors that may alter the blood pressure of women. The most common factor which makes the woman’s blood pressure different from man is the hormonal activity. Female hormones such as estrogen and progesterone play an important role in influencing the woman’s blood pressure. Below is the chart that indicates the different normal level of woman’s blood pressure according to age.
|Age of Female Individual||Normal Reading for Blood Pressure|
|15 to 18 years old||117/77 mmHg|
|19 to 24 years old||120/79 mmHg|
|25 to 29 years old||120/80 mmHg|
|30 to 35 years old||122/81 mmHg|
|36 to 39 years old||123/82 mmHg|
|40 to 45 years old||124/83 mmHg|
|46 to 50 years old||126/84 mmHg|
|51 to 55 years old||129/85 mmHg|
|56 to 60 years old||130/86 mmHg|
|60 and above||134/87 mmHg|
Normal Blood Pressure for Men ^
The normal blood pressure for men is higher than women. However, the normal level of adult male is 120/80 mmHg. The reading for male blood pressure varies according to age, as well. At the age of 35, adult men have higher risk of developing hypertension than adult women. Below is the chart that shows the different normal readings male individual’s blood pressure.
|Age of Male Individual||Normal Reading for Blood Pressure|
|15 to 18 years old||120/85 mmHg|
|19 to 24 years old||120/79 mmHg|
|25 to 29 years old||121/80 mmHg|
|30 to 35 years old||123/82 mmHg|
|36 to 39 years old||124/83 mmHg|
|40 to 45 years old||125/83 mmHg|
|46 to 50 years old||127/84 mmHg|
|51 to 55 years old||128/85 mmHg|
|56 to 60 years old||131/87 mmHg|
|60 and above||135/88 mmHg|
The normal blood pressure for men and woman may vary according to their age and current condition. For instance, female individual may have different blood pressure readings if they are pregnant. This is because the hormonal activity and the developing baby can alter the normal reading of female’s blood pressure. Blood pressure for men is slightly higher than women. This makes men have higher susceptibility rate for suffering from hypertension than women. However, women ages 60 and above have higher incidence of hypertension than men.
