GA2000S Function
The Aulisa sensor module(s) is a wearable device intended for vital signs detection
and physiological data transmission to the Receiver/Transponder via Bluetooth
technology. The Receiver/Transponder communicates with the Display Unit through
a customer Wi-Fi network implemented and managed by end users. The Display Unit
receives and displays physiological data as well as generates alarms for technical
errors or physiological events.
GA2000S Intended Use
The Guardian Angel®GA2000 Series Digital Vital Sign Monitoring System is intended
to help those who are interested in keeping watch on oxygen saturation level (SpO2),
pulse rate (PR) and armpit body temperature of their loved ones. The Guardian Angel
is not intended for medical use.
