Ventilator & Respirator Hardware and Software Reference Design

Reference design simulates basic human lung behavior. It is easy to test different pulmonary therapies without connecting a lung to the device. it represents a complex application where accurate measurement, correct instrumentation, power manager, and signal integrity are a critical factor for correct operation of a machine which a human life may depend on. A ventilator is a machine designed to mechanically move air in and out of the lungs to intermittently or continuously assist or control pulmonary ventilation. This device is primarily used in intensive therapy to help improve the patients breathing by regulating the flow of gas in the lungs. The most common indicators of the ventilation are the absolute volume and changes of volume of the gas space in the lungs achieved during a few breathing maneuvers
