What Does Blood Pressure in Kilopascals Mean?316

Blood pressure is a measure of the force exerted by the blood against the walls of the arteries. It is measured in millimeters of mercury (mmHg) or kilopascals (kPa). One kilopascal is equal to 7.5 mmHg. So, a blood pressure of 120/80 mmHg is equal to 16.0/10.7 kPa.

Blood pressure is an important indicator of cardiovascular health. High blood pressure, or hypertension, is a major risk factor for heart disease, stroke, and kidney disease. Low blood pressure, or hypotension, can also be a sign of a medical problem.

There are a number of factors that can affect blood pressure, including:* Age: Blood pressure tends to increase with age.
* Gender: Men generally have higher blood pressure than women.
* Race: African Americans have higher blood pressure than whites.
* Weight: Obesity is a major risk factor for high blood pressure.
* Diet: Eating a healthy diet, low in sodium and saturated fat, can help to lower blood pressure.
* Exercise: Regular exercise can help to lower blood pressure.
* Smoking: Smoking increases blood pressure.
* Alcohol: Excessive alcohol consumption can increase blood pressure.
* Stress: Stress can temporarily raise blood pressure.

Blood pressure is typically measured with a sphygmomanometer, which is an inflatable cuff that is placed around the upper arm. The cuff is inflated until the blood flow in the artery is blocked. The pressure in the cuff is then slowly released, and the blood pressure is measured when the blood flow is first heard. This is the systolic blood pressure. The cuff is then deflated until the blood flow is no longer heard. This is the diastolic blood pressure.

Blood pressure is classified as:* Normal: Less than 120/80 mmHg
* Elevated: 120-129/80-89 mmHg
* Stage 1 hypertension: 130-139/80-89 mmHg
* Stage 2 hypertension: 140/90 mmHg or higher
* Hypertensive crisis: 180/120 mmHg or higher

If you have high blood pressure, it is important to work with your doctor to lower it. Treatment may include lifestyle changes, such as losing weight, eating a healthy diet, and exercising regularly. Medication may also be necessary.

Low blood pressure is usually not a cause for concern. However, if you have symptoms of hypotension, such as dizziness, lightheadedness, or fainting, you should see your doctor.
