What indicates success when using NIV?

Successful use of noninvasive ventilation (NIV) is primarily indicated by improved ventilation and oxygenation. When a patient is effectively responding to NIV, you would expect to see notable enhancements in their gas exchange, leading to decreased carbon dioxide levels and increased oxygen saturation. These improvements typically manifest as the patient experiencing relief from symptoms such as shortness of breath and an overall reduction in respiratory distress.

In contrast, persistent respiratory distress would signal that the chosen intervention may not be effective, while increased levels of anxiety can often arise due to discomfort or worsening respiratory status, which goes against the goals of NIV therapy. Similarly, decreased patient comfort would indicate the opposite of successful treatment, as effective NIV should enhance a patient’s comfort level and tolerance of the therapy. Therefore, improved ventilation and oxygenation is the key indicator of successful NIV implementation.
