Cardiovascular disease (CVD), the leading cause of death globally, results in over 19 million deaths annually, according to the American Heart Association. High blood pressure is directly linked to increased risk for CVD. While an abbreviated daily IMST regimen has been shown to significantly reduce systolic blood pressure, the exercises are difficult to perform effectively using current devices, which offer limited user feedback.
Our respiratory training system, ReTrain, is comprised of an ergonomic, handheld device containing a one-way breathing valve, pressure transducer and ESP32 microcontroller. It senses and transmits the user’s breathing pressure over a Bluetooth Low Energy interface to a paired smartphone application. The accompanying smartphone application monitors breathing pressure and provides live feedback. The device requires minimal user interaction, and the intuitive framework of the app enhances user experience. For standard training and calibration, a real-time waveform of the user’s pressure and current target level are displayed with an accuracy of 3.5%. Additionally, data from each session is stored on the user’s device and transmitted to a clinical program via Amazon Web Service.
