Non-invasive ventilation (NIV) is the delivery of oxygen (ventilation support) via a face mask and therefore eradicating the need of an endotracheal airway. NIV achieves comparative physiological benefits to conventional mechanical ventilation by decreasing the work of breathing and improving gas exchange. Research suggests that non-invasive ventilation after early extubation looks helpful in reducing the total days spent on invasive mechanical ventilation. The intervention is recognised as an adequate treatment for respiratory failure in chronic obstructive pulmonary disease, cardiogenic pulmonary oedema and other respiratory conditions without complications such as respiratory muscle weakness, upper airway trauma, ventilator-associated pneumonia, and sinusitis.
