2. The burden of hypertension
Hypertension is one of the leading causes of death and disability in developing countries
Increases the risk of coronary arteries damage, heart attack, stroke, among others
By the year of 2025, 29% of the adult population will suffer from hypertension*
It is an indicator of other conditions such as pre-eclampsia
Hypertension is defined as BP> 140/90 mmHg in previously normotensive OR
Rise in BP of > 30/15 mmHg compared to BP at baseline

8. What can we do to improve this?
EWH-Oxford developed a low-cost, simple and easy-to-use device with mobile phone connection. However… It uses the oscillometric method
Can we improve the blood pressure measurement?
(accuracy of BP readings)
Can we use information from other sensors?
(ECG, PPG, etc …)
