Which of these is a challenge linked to mask leakage in NIV?

Mask leakage in noninvasive ventilation (NIV) can lead to inconsistent pressure delivery, which is a significant challenge. When there is a leak around the mask, the amount of air that the patient receives can fluctuate unpredictably. This inconsistency can undermine the effectiveness of the ventilation support, as it may prevent the patient from receiving the necessary pressure to maintain adequate ventilation and oxygenation.

Maintaining a proper seal is crucial for ensuring that the prescribed pressure settings are delivered consistently, which directly impacts the patient's breathing effectiveness. If the pressure is not consistent due to leaks, it may result in insufficient ventilation, worsening of respiratory distress, or even potential complications from inadequate oxygenation. Hence, addressing mask fit and minimizing leaks are key aspects of effective NIV management.
