The use of high-flow nasal cannula in patients with chronic obstructive pulmonary disease under exacerbation and stable phases: A systematic review and meta-analysis

For patients with chronic obstructive pulmonary disease (COPD) exacerbation, noninvasive ventilation (NIV) is recommended for those with respiratory acidosis and has been reported to reduce the need for invasive mechanical ventilation, while conventional oxygen therapy (COT) is mainly used for those without carbon dioxide (CO2) retention.1,2 NIV and COT are also reported to improve physiological outcomes, reduce hospital readmission rates when used in domiciliary settings, and improve exercise performance when applied during pulmonary rehabilitation.
