Design of Personal Health Monitoring Devices for Early Detection of Silent Hypoxia

Silent hypoxia in Covid-19 patients and symptoms of severe hypoxemia require appropriate treatment. These cases often appear asymptomatic but risk fatal to life-threatening. One of the recommended devices is pulse oximetry. Embedded systems technologies and the Internet of Things (IoT) can develop low-cost personal health monitoring devices. This study developed a pulse oximetry prototype integrated with a digital temperature sensor and equipped with the interpretation results of both "normal" and "hypoxic" conditions. It is called OxyTemp. IoT technologies monitor user conditions remotely using the Blynk application via mobile phones. This study used Research & Development with the Reverse engineering method. The OxyTemp has Different types of prototype testing are physical and functional inspection, electrical safety testing, and performance testing of each parameter using an appropriate calibrator. The working method refers to SK Direktur Jenderal Pelayanan Kesehatan Tahun 2018 No. 041-18 on Pulse Oximeter Testing Working Methods.
