Outline of Final Research Achievements

We proposed a new method to estimate mean blood pressure using only a smartphone and examined its accuracy. Firstly, we examined inter-method reliability across almost all models of iPhones and iPod touches, and revealed its high consistency. Secondly, a new type, non-invasive continuous blood pressure monitors were developed. Finally, we revealed that mean blood pressure estimated from heart rate and modified normalized pulse volume derived using only a smartphone was fairly accurate.
