A ventilators is a machine that helps patients take breaths if they can not do it on their own. People also often refer to it as a breathing machine. Technically, a ventilator is a mask that medical workers wear when they care for someone with a lung illness. A ventilator is a bedside machine with tubes that connect to patients airways. Ventilators help pump oxygen into patients lungs. The air flows through a plastic tube that goes in patient’s mouth and down pateint’s windpipe. In this study, a mechanical ventilator that uses air pump technology is developed. Air for patients is pumped by a electrical air pump in the ventilator. The air volume and ratio provides to pateints could be controlled by a Electronic Control Unit (ECU) of the ventilator. The air volume and ratio is set to three type of adults, children and infant patients. There are two modes of breathing for patients in this ventilator. The first mode is Continuous Positive Airway Pressure (CPAP) and the second mode is Volume – Assist Control (V-AC). A a prototype of the ventilator is created and some experiments have been carried for validation the parameters of the ventilator with laboratory test.
