  "abstract": "<p>Positive pressure ventilation (PPV) mode is the direct application of air to the patient&rsquo;s<br>\nlungs and is the most commonly used ventilation mode for passive patients. Mechanical<br>\nventilators are life-saving medical equipment if a person is unable to breathe on their own.<br>\nDue to the scarcity and unavailability of the machines, patients are not getting assistance.<br>\nThe proposed thesis aims to design a low-cost volume and pressure-controlled mechanical<br>\nventilator for pandemic emergencies and scarcity. A Fuzzy logic controller is used to<br>\ncontrol both the pressure and volume parameters. The designed system can be used for<br>\ndifferent patients that need different tidal volumes and pressure. The clinician can set the<br>\ntidal volume and airway pressure depending on the lung requirements. A piston cylinder<br>\nmechanism is used to deliver the required volume and pressure of gas to the pneumatic<br>\ncircuit. Armature controlled DC motor is used to drive the ventilator mechanism, and its<br>\nmodel is used to determine the maximum displacement, velocity, and delivery capacity of<br>\nthe mechanism. The testing is done by interfacing the sensors and actuators and deploying<br>\nthe Simulink model on an Arduino mega controller. A medical linear test lung simulator is<br>\nused for the test</p>",
