IntroductionEdit

Mechanical ventilation is a form of organ supportive therapy which employs breathing assist devices in circumstances when the patient's breathing apparatus is unable to provide sufficient vital gas exchange. Such devices range from simple human-powered "Bag-Valve-Mask" Ventilators to electricity-powered, compressor-driven, computerized Ventilators. A simple overview is provided in Fig 1.
