High-Frequency Chest Wall Oscillation in Critical Care: A Systematic Review

Current evidence suggests that HFCWO is a safe and feasible airway clearance strategy in selected ICU patients with secretion burden without proved effects on the main clinical ouctomes. However, robust data supporting its routine use to improve hard clinical outcomes are lacking. Well-designed, adequately powered randomized trials are needed to define patient selection criteria, optimal timing, and the true clinical impact of HFCWO in the ICU setting.
