Randomized Controlled TrialIncreasing pressure support does not enhance secretion clearance if applied during manual chest wall vibration in intubated patients: a randomised trial.
What is the effect of increasing pressure support during the application of manual chest wall compression with vibrations for secretion clearance in intubated patients in intensive care? ⋯ Although increasing pressure support has previously been shown to increase secretion clearance in intubated patients, the current study did not show any benefits when it was added to chest wall compression with vibrations.

Randomized Controlled TrialA pilot study of the impact of high-frequency chest wall oscillation in chronic obstructive pulmonary disease patients with mucus hypersecretion.
Chronic obstructive pulmonary disease (COPD) patients with mucus hypersecretion tend to demonstrate increased frequency of infective exacerbations and a steeper slope of decline in lung function. Enhanced mucociliary clearance with high-frequency chest wall oscillation (HFCWO) devices previously used in cystic fibrosis and bronchiectasis patients may offer the opportunity for community-based, self-managed therapy to improve quality of life and lung function. ⋯ This pilot study demonstrated that patients with advanced COPD and mucus hypersecretion at increased risk of declining lung function tolerated the HFCWO treatment well, leading to improvement in quality of life and reduced symptoms.

Randomized Controlled Trial
Direct versus video laryngoscopic intubation by novice prehospital intubators with and without chest compressions: A pilot manikin study.
To evaluate whether chest compressions affect the time taken for intubation (TTI) using the Macintosh laryngoscope and two portable video laryngoscopes (VLs) (GlideScope Ranger and Airway Scope) when used by novice prehospital caregivers, and to compare the TTIs and rates of successful intubation among the three laryngoscopes with and without chest compressions in a manikin model. ⋯ In this pilot study, chest compressions did not significantly affect the TTI using the Macintosh laryngoscope and two portable VLs when used by novice prehospital caregivers in the manikin model on the floor. Considering the fairly short training time, two portable VLs may be potentially useful adjuncts for tracheal intubation during chest compressions for novice prehospital caregivers. Further studies are required to validate whether these findings are clinically relevant.

Randomized Controlled Trial Clinical Trial
Safety, tolerability, and efficacy of high-frequency chest wall oscillation in pediatric patients with cerebral palsy and neuromuscular diseases: an exploratory randomized controlled trial.
Airway secretions and infections are common in cerebral palsy and neuromuscular diseases. Chest physiotherapy is standard therapy but effort is substantial. High-frequency chest wall oscillation is used in cystic fibrosis but tolerability and safety data in cerebral palsy and neuromuscular disease are limited. ⋯ Our data suggest safety, tolerability, and better compliance with high-frequency chest wall oscillation. Improvement in airway clearance may help prevent hospitalizations. Larger controlled trials are required to confirm these results.

Randomized Controlled Trial Comparative Study
Comparison of settings used for high-frequency chest-wall compression in cystic fibrosis.
Cystic fibrosis (CF) patients commonly use a high-frequency chest-wall compression (HFCWC) device for airway clearance that generates oscillatory flow with a sine-wave configuration. Typical HFCWC settings combine a lower Vest inflation pressure setting (eg, 5 on the Vest's arbitrary 1-10 scale for the setting that controls the background pressure of the inflatable vest) with mid-range frequency (14-16 Hz) (lower-pressure/mid-frequency HFCWC). ⋯ In adult CF patients, single-session higher-pressure/variable-frequency HFCWC resulted in greater sputum expectoration by wet weight, but not other differences, compared to the commonly used lower-pressure/mid-frequency settings. Longer-term comparisons are needed in a larger, more diverse population to determine whether sustained use of the higher-pressure/variable-frequency settings results in clinically important differences in outcomes.
