Comparing two techniques for clearing mucus in patients on mechanical ventilation

Evaluating the Short-term Efficacy of Two Oscillation Techniques in Hypersecretive Mechanically Ventilated Patients: a Randomized Crossover Trial

Not applicable Interventional Capital Medical University · NCT06675942

This study is testing two different ways to help clear mucus from the lungs of patients on mechanical ventilation to see which method works better for their breathing.

What this trial studies

This study evaluates the effectiveness of two airway clearance techniques, oscillation and lung expansion (OLE) and high-frequency chest wall oscillation (HFCWO), in improving lung aeration and ventilation distribution in hypersecretive patients requiring long-term mechanical ventilation. It is a randomized cross-over study involving patients with tracheostomy tubes who have been admitted to the ICU and are experiencing airway hypersecretion. The study aims to establish a more effective method for mucus removal, which is crucial for preventing complications such as pneumonia and atelectasis in these patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with airway hypersecretion who require more than 48 hours of mechanical ventilation in an ICU setting.

Not a fit: Patients with conditions such as malignant arrhythmia, acute myocardial ischemia, or other severe lung diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved airway clearance techniques, reducing the risk of pneumonia and enhancing recovery in mechanically ventilated patients.

How similar studies have performed: While there is ongoing research in airway clearance techniques, this specific comparison of OLE and HFCWO in this patient population is novel and has not been extensively tested.
