What is the main objective during the initial setup of noninvasive ventilation?

The main objective during the initial setup of noninvasive ventilation is to ensure proper mask fit. A secure and comfortable mask fit is crucial for the effectiveness of noninvasive ventilation. If the mask does not fit well, it can lead to air leaks, which diminishes the effectiveness of the ventilation support and can cause increased patient discomfort and anxiety. A proper fit also helps prevent complications such as skin breakdown or pressure ulcers from an ill-fitted mask.

While achieving the desired tidal volume is important in a broader treatment context, it is secondary to ensuring that the mask is properly seated on the patient's face to facilitate effective ventilation. If the mask does not fit properly, it becomes difficult, if not impossible, to maintain the targeted tidal volumes regardless of the settings on the ventilator. Therefore, achieving a good mask fit must be prioritized during the initial setup process.
