Is blood pressure normal? Do you know about blood pressure?

summary

Blood pressure refers to the lateral pressure of the blood in the blood vessel on the wall of the blood vessel per unit area. The blood pressure can be measured by the sphygmomanometer to see if it is in the normal range. If not in the normal range, you need active treatment, blood pressure between 100-140 to take medicine?

Is blood pressure normal? Do you know about blood pressure?

First, the systolic blood pressure of normal adults is 12.0-18.6kpa (90-140mmhg). But after 40 years old, systolic blood pressure increased with age. 6 kPa (140 mmHg) under 40 years old. 41-50 years old < 20KPa (150mmhg). 51-60 years old < 21.3kpa (160mmhg). More than 60 years old < 22kpa (170mmhg). The average systolic blood pressure of newborns was 6.0-8.0 kPa (50-60 mmHg). The average diastolic blood pressure was 4.0-5.3kpa (30-40mmhg). Systolic blood pressure ≤ 80 + age (years) × 2mmhg (1mmhg = 0.133kpa)

Second, the diastolic blood pressure of normal adults is 8.0-12.0 kPa (60-90 mmHg). The pulse pressure was 4.0-5.3kpa (30-40mmhg). The blood pressure of the two upper limbs of healthy people may not be equal, and the difference between the left and right sides can reach 0.6-1.3kpa (5-10mmhg). The blood pressure of lower limbs is about 2.6-5.3kpa (20-40mmhg) higher than that of upper limbs. The blood pressure of adult male is slightly higher than that of female, and there is little difference between male and female in old age. The blood pressure of normal people is lower in the morning, but higher in the morning, after work and satiety. The blood pressure can be decreased in the hot environment, but it can be increased in the cold environment. In addition, emotional tension, strenuous exercise, drinking, smoking, etc., can affect blood pressure.

Third: heart rate: the heart rate of normal adults is 60-100 beats / min, most of them are 60-80 beats / min, slightly faster in women; children under 3 years old are often more than 100 beats / min; the elderly are slow.

matters needing attention

1. Identify diseases. For example, if the patient faints after drug injection and blood pressure is measured, the normal one is the patient with needle syncope, and if it is low or can not be measured, it is anaphylactic shock. 2. Diagnosis of disease. Patients with hypertension and hypotension can be diagnosed by measuring their blood pressure. 3. Guide medication. If high blood pressure patients with dizziness, through the measurement of blood pressure, low can no longer use antihypertensive drugs, and high blood pressure dizziness need to use antihypertensive drugs.
