Fraction of Inspired Oxygen and Humidity Control of Ventilator

The virus problem that is currently endemic in the world makes many people suffer from respiratory diseases. The increase in patients is not accompanied by the number of tools available. The provision of respiratory support should not be regulated arbitrarily because it can cause excess or lack of oxygen levels that can endanger the patient. Because of this, a ventilator is made that can be adjusted to the level of the fraction of inspired oxygen. The user can set the required fraction of inspired oxygen level on the Arduino application. OOM202 oxygen sensor is used as a sensor that will read the given fraction of inspired oxygen level. The fraction of inspired oxygen levels that can be given are at values of 30%, 60%, and 80% with an accuracy of 96.68%. A fuzzy logic control algorithm is used which can guess the length of time the valve must be open to get a certain level of fraction of inspired oxygen. In addition, there is also humidity control so that the inhaled gas does not dry out with the help of an ultrasonic mist maker and DHT22 is used as a sensor that will read the given relative humidity level. The given relative humidity level is over 90% with an accuracy of 99.9%.
