Blood pressure


Hypertension or high blood pressure sometimes called “silent killer”, symptoms are not appreciable in early stages until it develops to serious health risk. For example one of three adults in the United States has high blood pressure (NHLBI). Blood pressure (BP) is the pressure or blood force created during heart's muscle contraction, where blood moves through the vascular system. Systolic (SBP) and diastolic (DBP) blood pressures are expressed in different cardiac cycles. Systolic pressure is created during the contraction of the heart ventricles, and diastolic pressure is the pressure between ventricular contractions. Systolic and diastolic blood pressures are expressed for example into 125/85 mmHg which is normal blood pressure.

It is important assess your cardiovascular function by blood preassure meassurement. Normally it can be meassured with tonometer, however in this project the same thing achieved by ECG and PPG signal waves (or only by PPG signal wave). Picture above explains how.
