Portable Low Cost Ventilator for Controlling Arduino Based on IoT Technique

Human lungs use the reverse pressure generated by contraction motion of the diaphragm to suck in air for breathing. A contradictory motion is used by a ventilator to inflate the lungs by pumping type motion. A ventilator mechanism must be able to deliver in the range of10 – 30 breaths per minute, with the ability to adjust rising increments in sets of 2. Along with this the ventilator must have the ability to adjust the air volume pushed into lungs in each breath. Our system makes use of blood pressure sensor along with sensitive heart Beat sensor to monitor the necessary vitals of the patient and display on a webpage using IOT. When any abnormality in the HB or BP the ventilator bag automatically pumping also according the value of the Sensors the inhalation speed also varying correspondingly. The entire system is driven by arduino controller to achieve desired results and to assist patients in COVID pandemic and other emergency situations. The body temperature sensor LM35 used to sense the temperature of the patient and Pressure sensor used sense the Pressure value and Heart beat sensor to pulse of the patient. All the sensor values processed in Atmega328 arduino controller and checking for the threshold settings. If threshold exists the controller will send a signal to the servo motor in the ventilator mechanism. The NodeMCU IOT module used here to send values to cloud server for doctor checkup from remote. All the Values are displaying in LCD.
