Dyspnea During Noninvasive Ventilation Implications for Respiratory Function

Abstract

Dyspnea is a common and disturbing symptom that hosts multiple subjective experiences, and therefore, it is very hard to classify. Although noninvasive ventilation (NIV) can reduce it, respiratory discomfort can persist, reappear, or increase after NIV, and it can be multifactorial. Dyspnea during NIV is prevalent and is associated with worse prognosis.
