Vital Sign Monitoring Spo2 and BPM (Photoplethysmograph Method)

Abstract

The condition of the human body can be seen through vital signs on the human body. Blood oxygen saturation (SpO2) and heart rate (BPM) are part of human vital signs which are important for regular checks to determine human health status. This research was conducted to create a vital sign tool as a tool that can measure both vital signs simultaneously. The design of the tool is made with a fingertip accessory design that is placed on the patient's fingertip where there is a MAX30102 sensor which is tasked with detecting human SpO2 and BPM levels. Then the data will be processed by the ESP32 as a microcontroller and displayed on the Nextion screen. The results of the tool show that the average error data for measuring SpO2 is ±0.02% and the average error for measuring BPM is ±0,16%. By making this tool, it is hoped that it will make it easier to check human vital signs, especially measuring oxygen saturation and heart rate, so that human health conditions remain monitored.
