Evaluating the Short-term Efficacy of Two Oscillation Techniques in Hypersecretive Mechanically Ventilated Patients

The OLE device (MetaNeb system) is a newer, noninvasive physiotherapy tool that combines mechanical and pharmacological interventions (aerosols) to help mobilize endobronchial secretions.

High-frequency chest wall oscillation (HFCWO) is an airway clearance technique that uses external forces applied to the chest via an inflatable vest connected to a device that generates vibrations at varying frequencies and pressures.
