Alphamed adopts the principle of oscillography method to measure blood pressure. Blood pressure refers to the lateral pressure, or pressure, of the blood in the blood vessel against the wall of the blood vessel per unit area. The blood pressure of human body changes along with time cycle,systolic pressure is the maximum that points
to blood pressure, diastolic pressure is the minimum value that points to blood pressure, that is to say the static pressure of blood inside blood tube is blood pressure.
