Blood Pressure

Description

What is the Test?
A blood pressure test measures the force of blood against the walls of your arteries as your heart pumps. It’s expressed in millimeters of mercury (mmHg) and recorded as two numbers: systolic (when the heart beats) and diastolic (when the heart rests between beats).

How the Test is Done?
The test is typically performed using a sphygmomanometer (blood pressure cuff) and a stethoscope. The cuff is placed around your upper arm and inflated to constrict blood flow. As the cuff deflates, a healthcare provider listens with a stethoscope to the blood flow sounds or uses an automated device to measure your blood pressure. The test is quick and non-invasive.

Preparation Required:
No special preparation is needed, but it’s recommended to avoid caffeine, smoking, and strenuous exercise for at least 30 minutes before the test. Ensure you’re relaxed and seated comfortably with your arm supported at heart level during the measurement.

Significance of the Results:
Normal blood pressure is typically around 120/80 mmHg. Elevated or high blood pressure (hypertension) can increase the risk of cardiovascular diseases, including heart attack and stroke. Low blood pressure (hypotension) can cause dizziness and fainting. Regular monitoring helps manage and prevent potential health issues related to blood pressure.
