Overview
This is a supplementary device for neonatal resuscitation simulation training that connects a Bluetooth® Chestpiece and an instructor's controller (smartphone) via Bluetooth. Heartbeat sounds, synchronized with the heart rate (HR) set by the instructor, can only be heard when the chestpiece is placed on a neonatal manikin. By connecting the controller to a training monitor (tablet) via Wi-Fi, simulated HR, oxygen saturation (SpO₂), and ECG waveform set on the controller can be displayed on the monitor. Trainees can assess vital signs through the monitor and auscultation to perform appropriate procedures, while instructors can observe their actions and adjust the vital signs using the controller.
The training monitor also supports playing neonatal crying sounds. If the monitor is not used, the sounds will be played via the controller or Bluetooth Chestpiece. The dedicated application "Saving baby" can be used simply by installing it on commercially available smartphones or tablets. Compared to conventional simulators, it enables low-cost and effective neonatal resuscitation simulation training.

Features
Controller & Monitor
The heart rate and SpO2 values operated on the controller are reflected on the monitor. ECG and ECG sound are also simulated according to the heart rate and SpO2 values.

Controller without Monitor Connection
When only one smartphone or tablet is available, the controller can be used without connecting to a monitor. In this mode, sounds of baby’s cries are played on the device functioning as the controller. This mode is intended for use when multiple devices are not available, and the focus is solely on heart auscultation training.
The sound of baby's cries and secretions is played back on the device used as the controller.

This mode can be used when there are not multiple devices available and it is used solely for heart auscultation training.
