About Blood Pressure
What are systolic pressure and diastolic pressure?
When ventricles contract and pump blood out of the heart, the blood
pressure reaches its
maximum value in the cycle, which is called systolic
pressure. When the ventricles relax, the blood pressure reaches its
minimum value in the cycle, which is called diastolic pressure.
What is the standard blood pressure classification?
The blood pressure classification published by World Health
Organization (WHO) and International Society of Hypertension (ISH) in
1999 is as follows:
Only a physician can tell your normal BP range. Please contact a physician if
your measuring result falls out of the range. Kindly note that only a physician
could tell whether your blood pressure value has reached a dangerous point.
