The use of noninvasive ventilation (NIV) in acute hypercapnic respiratory failure, cardiogenic pulmonary oedema, acute lung injury/acute respiratory distress syndrome (ARDS), community-acquired pneumonia and weaning/post-extubation failure is considered common in clinical practice. Herein, we review the use of NIV in unusual conditions. Evidence supports the use of NIV during fibreoptic bronchoscopy, especially with high risks of endotracheal intubation (ETI), such as in immunocompromised patients. ⋯ The role of assisted ventilation during exercise training in chronic obstructive pulmonary disease patients is still controversial. NIV should be applied under close monitoring and ETI should be promptly available in the case of failure. A trained team, careful patient selection and optimal choice of devices, can optimise outcome of NIV.
