High-flow nasal cannula versus noninvasive ventilation in acute heart failure–related respiratory failure: a systematic review and meta-analysis
Background Noninvasive ventilation (NIV) is the recommended first-line respiratory support for acute heart failure (AHF)–related respiratory failure. However, its tolerance is often limited. High-flow nasal cannula (HFNC) has emerged as a potential alternative, but comparative evidence remains inconsistent. This study...
