Blood pressure can be measured by a sphygmomanometer, or blood pressure monitor.
Having high blood pressure for a short time can be a normal response to many situations. Acute stress and intense exercise, for example, can briefly elevate blood pressure in a healthy person.
For this reason, a diagnosis of hypertension normally requires several readings that show high blood pressure over time.
The systolic reading of 130 mmHg refers to the pressure as the heart pumps blood around the body. The diastolic reading of 80 mmHg refers to the pressure as the heart relaxes and refills with blood.
The AHA 2017 guidelines define the following ranges of blood pressure:
Systolic (mmHg)
Diastolic (mmHg)
Normal blood pressure
Less than 120
Less than 80
Elevatedë
Between 120 and 129
Over 80
Stage 1 hypertension
Between 130 and 139
Between 80 and 89
Stage 2 hypertension
At least 140
At least 90
Hypertensive crisis
Over 180
Over 120
If the reading shows a hypertensive crisis when taking blood pressure, wait 2 or 3 minutes and then repeat the test.
If the reading is the same or higher, this is a medical emergency.
The person should seek immediate attention at the nearest hospital.
