Perancangan Prototipe Portable Ventilator untuk Pasien COVID-19 di Pekanbaru

Abstract

Currently, the world is facing a coronavirus pandemic. In Indonesia, until April 8, 2020, there have been 2,956 cases of COVID-19, with details of 2,494 being treated, 222 people cured, and 240 people dead. The increasing number of patients infected with COVID-19 has caused hospitals in Indonesia to lack medical aids, one of which is a ventilator. In this study, a portable ventilator was designed using NodeMCU ESP8266 microcontroller to process data so that it could be displayed on the LCD and the Firebase database. From the analysis results obtained both in terms of NodeMCU ESP8266 voltage, L298N Driver Module power supply, Buzzer, 4x4 Keypad Module, Portable Ventilator monitoring through the Android application with the Firebase database, to PEEP and tidal volume for CMV mode with Low, High, V. High readings obtained were 1.86 cmH2O & 105.71 mL; 2,3 cmH2O & 131 mL; and 6.29 cmH2O & 163.26 mL. Then for the second mode, CPAP mode, the readings were 5.13 cmH2O & 86.65mL; 5.9 cmH2O & 65.89mL; and 6.45 cmH2O & 102.6 mL. This proves that the overall system of the Portable Ventilator is functioning properly. From the tests that have been carried out on the Portable Ventilator Prototype that the examiner designed, the accuracy is obtained based on the performance of the tool which is in CMV and CPAP mode at speeds ranging from 'Low', 'High', and 'V.High' (Very High) respectively each one can run smoothly.
