Heart diseases are responsible for 31% of all global deaths. Existing blood pressure and flow measurement relies on expensive, static single measurement systems. Flo is a revolutionary approach based on extensive research in the UK and Columbia. Three key technologies -- mobile low-cost ultrasound transducers, mobile computing, and AI -- combine to allow a genuine step-change in early heart attack and stroke detection. The mobility of the system and its low cost allow for true beat-to-beat continuous pressure and flow monitoring within the brain, vastly improving diagnosis accuracy and access to a greater global patient population.
