Blood pressure is the force of blood pushing against the wall of the arteries. Systolic pressure which is the highest blood pressure occurs when our heart is pumping. Diastolic pressure is lowest blood pressure when our heart is resting.
The unit for blood pressure is mmHg and the notation will be systolic followed by diastolic pressure. Normal blood pressure is less than 120/80mmHg. Blood pressure of 140/90mmHg is considered high blood pressure or hypertension.
Hypertension is a critical risk factor for cardiovascular morbidity and mortality in the general population and reduction of blood pressure (BP) with effective antihypertensive therapy significantly decreases cardiovascular morbidity and mortality [12]. In patients with hypertension, the proposed system will warn patients to take medicines and pay attention to diet, to get treatment effect.
So design framework along with a wearable blood pressure sensor should be implemented to suit into the existing android platform. The information gathered will be sent by Bluetooth technology to the android system for monitoring.
