Our body has a proper circulatory system. Arteries take the purified or oxygenated blood from the heart to different parts of the body, while veins take the deoxygenated blood from different part to the lungs for purification. The heart pumps the blood in a rhythmic manner with a particular pressure and this is known as blood pressure. In other words, the pressure which is experienced in the arteries when your heart pumps the blood to other parts of your body is known as blood pressure. It is measured in the terms of systolic and diastolic pressure. The pressure measured at the time of heart contraction, is known as systolic pressure and when it relaxes, the pressure is known as diastolic pressure. A blood pressure chart consists of both systolic and diastolic readings. For example if your blood pressure is 120/80 mmHg then the systolic blood pressure will be 120 and 80 will be the diastolic blood pressure.

Blood pressure depends upon the systolic and diastolic pressure noted at various periods and in various people. 120/80 mmHg is considered as normal blood pressure. Pressure above this reading is known as high blood pressure and below the normal readings is known as low blood pressure.

Chart for Blood Pressure Levels

Given here is the blood pressure level chart for adults in which you can see systolic and diastolic readings.

Normal Blood Pressure100 - 13070 - 85
High Normal Blood Pressure130 - 14085 - 90
High Blood Pressure140 - 16090 - 110
High Blood Pressure (Hypertension)160 - 230110 - 135

Pediatric Blood Pressure Level Chart

Chart for blood pressure levels for children depends upon their age, sex, height and health. It also depends on the child's surroundings where he/she is growing. In case of small kids even a slight change in the blood pressure can also be very dangerous.

Age (in years)Male (mmHg)Female (mmHg)
1 to 380/34 to 120/75 83/38 to 117/76
4 to 688/47 to 128/8488/50 to 122/83
7 to 1092/53 to 130/9093/55 to 129/88

Factors Affecting Blood Pressure

There are many factors on which blood pressure depends and fluctuate. Some factors are controllable while others, like diabetes or any other hereditary factor, are not. Following are some of the factors which affect the normal blood pressure range.
  • Regular exercises may reduce the blood pressure. Hence people suffering from some cardiovascular disease should go for proper exercise for a healthy body.
  • Use of alcohol can drastically raise the blood pressure and may be responsible in shooting it to the maximum levels.
  • Mental stress may also be responsible for increasing your blood pressure.
  • Smoking is another factor responsible for shooting up the blood pressure.
  • Eating habits can be one of the major cause for fluctuating blood pressure. Maintain a healthy diet to keep the blood pressure normal.
Now you can easily find out from the above given chart which level you fall under. Blood pressure readings for children and for adults also help you to know your body condition. Extreme low or high blood pressure can be fatal. Hence, consult a doctor if you are not under the normal blood pressure category. Follow simple ways to stay away from blood pressure problems. Reduce salt and sodium content from your diet and concentrate on healthy nutritious food. Limit your alcohol consumption and stop smoking. Perform regular exercises as they are very effective in bringing blood pressure to normal. Follow a healthy lifestyle and stay fit.
