    Respiratory diseases and injury induced respiratory failures have become a major public health problem in the world. These diseases are enhanced by air pollution, smoking, and burning of biomass for fuel, all of which are on the rise in developing countries. Patients with these respiratory diseases may undergo breathing difficulties. A medical ventilator is a device which helps in such situations when patients have difficulties to breathe on their own. It comes in many different varieties .These are mainly used in intensive care units in hospitals, in homecare and when transporting patients. Portable ventilators are compact devices designed to provide mechanical ventilation in settings where piped gases and mains electricity are unavailable whereas in ambulances while the patient is transporting. Unfortunately automated portable medical ventilators available today are expensive. When considering a developing country like Sri Lanka, it is difficult to afford such a large amount for a portable ventilator Only a few portable ventilators are available in Sri Lanka hospitals. Lack of portable ventilators has become one of the leading causes of death during the transportation of patients who have breathing difficulties. Therefore the main objective of this project is to develop an automated portable medical ventilator at a low cost with better reliability and acceptable accuracy using available resources.
