What does adequate pressure management in NIV aim to prevent?

Adequate pressure management in noninvasive ventilation (NIV) primarily aims to prevent excessive CO2 buildup. In conditions such as chronic obstructive pulmonary disease (COPD) or acute respiratory failure, proper pressure settings ensure that the patient can effectively exhale carbon dioxide. If pressures are too low or inadequate, the patient's ability to ventilate and effectively eliminate CO2 is compromised, leading to respiratory acidosis and further complications.

While patient anxiety, mask dislodgement, and increased tidal volume are important considerations in NIV, they are secondary to the primary respiratory goals. Adequate pressure management is essential for maintaining optimal gas exchange and preventing hypercapnia, which is critical in managing patients requiring noninvasive ventilation.
