The kPa, or kilopascal, on a blood pressure monitor is a unit of measurement of pressure. Kilopascals (kPa) and millimeters of mercury (mmHg), the same, are expressed pressure, usually 1kPa is equal to about 7.5mmHg, 1mmHg is equal to 0.133kPa. our country is now more millimeters of mercury (mmHg) measurement of blood pressure. When measuring blood pressure with a sphygmomanometer, it should be noted that it is necessary to rest in a quiet environment for at least 20 minutes, to be stabilized after the heart rate and then measure the pressure, in addition, it should also be noted that the cuff is placed on the upper arm and the level of the heart level line at the same place, elasticity and then can be put into the one finger is appropriate. The diagnosis of hypertension requires three blood pressure measurements in one day, if the blood pressure systolic blood pressure and diastolic blood pressure & gt; 140/90mmHg (adults), or systolic blood pressure & gt; age * 2 + 100 (children), it can be roughly confirmed as high blood pressure. Hypertension should also be graded after diagnosis, and a physician should be consulted to take medication on a regular basis.
