The One Heart App is a congenital heart disease (CHD) educational screening solution to reach the 90% of children in the world who do not have access to quality cardiac care. The One Heart App enables healthcare workers to reach remote and underserved populations and provide CHD screening using a digital stethoscope and a mobile device. The One Heart App allows users to create an account, add patients, record heart sounds, assign patients to an expert user, complete consultation of assigned patients, and review consultation results. There are three primary users for the One Heart App including general users, nurses, and pediatric cardiologists (expert users). Please Note: the demo version of this application is available for anyone to download, however, the use of the machine learning algorithms integrated in version 1.2 are restricted to institutional users who have ethical clearance and are using the One Heart App for clinical investigative purposes only.

By connecting Bluetooth® Chestpiece, instructor's controller (smartphone), and simulated monitor (tablet) via Bluetooth®, we achieved a more practical and highly effective simulator at low cost. Heart auscultation linked to an instructor-set scenario is possible only when the Chestpiece is placed on a newborn mannequin. Also, a tablet, which serves as a simulated monitor, displays heart rate, oxygen saturation, and ECG waveform, allowing the instructor to change vital information via the controller based on the trainee's treatment situation. Furthermore, the simulated monitor also supports playback of newborn cries. It can be used simply by installing a dedicated application on commercially available smartphones and tablets, and can be introduced at a lower cost compared to traditional simulators. SupportOS: iOS 16 - 18, 26 Online Manual: https://app.elecom.co.jp/nrtrainer/manual_en.html * This app and product are intended for training purposes for the educational purposes of medical professionals and are not medical devices.
