What can happen if a patient experiences significant air leaks during NIV?

Significant air leaks during noninvasive ventilation (NIV) can compromise the effectiveness of the therapy, often necessitating a mask refitting or adjustment. When air leaks occur, they can lead to inadequate ventilation and reduced pressure support, which may prevent the delivery of the intended level of positive airway pressure to the patient. This can result in suboptimal oxygenation and ventilation outcomes.

Adjusting the mask or refitting it properly can help establish a better seal, thereby minimizing leaks. A properly fitted mask is crucial to maintaining the required pressure and ensuring that the patient receives the necessary respiratory support. Effective management of air leaks is essential for the success of NIV treatments, as persistent leaks can hinder the therapeutic goals of improving respiratory function and oxygenation.
