INFORMATION OF BLOOD PRESSURE
What is blood pressure?
Blood is sent to the arteries with the action of a pump called heart(contraction and dilation). The pressure of blood leaving
the heart is called “blood pressure”. Blood pressures pulsate with each beat of the heart. The high blood pressure when the
heart contracts is called “systolic pressure” and the low blood pressure when the heart dilates is called “diastolic pressure”.
The threshold value for hypertension in adults is defined by the World Health Organization (WHO) as 140/90 mmHg .
Health and blood pressure
When people reach middle age, the risk of hypertension markedly increase. With aging, the blood vessels age rapidly.
Furthermore, because of the obesity and lack of exercise, cholesterols stick to blood vessels, causing them to lose elasticity.
Therefore, watching daily blood pressure help evaluate our health condition.
Why do we need to monitor blood pressure at home?
By monitoring at home, you may manage your health between doctor visits. Home monitoring also provides you with a
record of blood pressure measurements over time to give your doctor - a valuable tool in hypertensive monitoring. Home
monitoring may also alleviate white coat hypertension.
This term refers to the phenomena which causes individuals’ blood pressure to be higher when taken in a medical office
setting. This is due to the stress of being in a medical office setting which may cause blood pressure to rise higher than
normal. When monitoring at home, you may get a more accurate measurement of your blood pressure in a normal,
relaxed state.
