Clinical Application and Outcome of Non-invasive Ventilation in Different Chest Diseases

Noninvasive ventilation is increasingly used method of respiratory management in both the emergency room and critical care. Noninvasive ventilation delivers mechanically assisted breaths without the placement of an artificial airway and has become an important mechanism of ventilator support inside and outside the intensive care unit.

Noninvasive ventilation is further subdivided into negative pressure ventilation which is the iron lung, first used in 1928 and the Hayek oscillator, is a more recently designed to provide negative pressure during inspiration and positive pressure during expiration. Noninvasive positive pressure ventilation can be used as continuous positive airway pressure or bi-level positive airway pressure.
