Randomized Controlled Trial
Effectiveness of a new "focused pulse" high-frequency chest wall oscillation in patients with moderate to severe COPD.
Chest physiotherapy plays a crucial role in the treatment of COPD, although the optimal techniques for airway clearance have not been definitively established. Among the different techniques, high-frequency chest wall oscillation (HFCWO) has gained attention for its potential to create a widespread lung percussion, facilitating the removal of secretions and potentially clearing the peripheral bronchial tree. This study aims to assess the effectiveness of a novel "focused pulse" HFCWO in patients with moderate to severe COPD. ⋯ The focused pulse HFCWO technique improves daily life activities and lung function in patients with stable COPD. The device demonstrated significantly greater effectiveness in lowering COPD exacerbations as well as visits to ED or practitioner.

Randomized Controlled Trial
Effectiveness of two high-frequency chest wall oscillation techniques in patients with bronchiectasis: a randomized controlled preliminary study.
Chest physiotherapy is an important tool in the treatment of bronchiectasis. High-frequency chest wall oscillation (HFCWO) is a technique designed to create a global percussion of the lung which moves secretions and probably clears the peripheral bronchial tree. We propose the comparison between an existing device (SmartVest) and a new device (RespIn 11). ⋯ The two machines have improved health and quality of life scores in patients with bronchiectasis. RespIn 11 also demonstrated a significant lowering of exacerbations and a better patient acceptance.

Immediate Effects and Safety of High-Frequency Chest Wall Compression Compared to Airway Clearance Techniques in Non-Hospitalized Infants With Acute Viral Bronchiolitis.
No studies have investigated the use and safety of high-frequency chest wall compression (HFCWC) for non-hospitalized infants with acute viral bronchiolitis (AVB). The aim of the present study was to evaluate the immediate effects and safety of HFCWC as compared to airway clearance techniques in children with AVB. ⋯ The use of HFCWC induced similar clinical effects as airway clearance techniques and was safe for non-hospitalized infants with AVB. Both techniques reduced respiratory symptoms and acutely improved [Formula: see text]. (ClinicalTrials.gov: NCT03835936.).

Randomized Controlled Trial
Chest physiotherapy improves lung aeration in hypersecretive critically ill patients: a pilot randomized physiological study.
Besides airway suctioning, patients undergoing invasive mechanical ventilation (iMV) benefit of different combinations of chest physiotherapy techniques, to improve mucus removal. To date, little is known about the clearance effects of oscillating devices on patients with acute respiratory failure undergoing iMV. This study aimed to assess (1) the effects of high-frequency chest wall oscillation (HFCWO) on lung aeration and ventilation distribution, as assessed by electrical impedance tomography (EIT), and (2) the effect of the association of HFCWO with recruitment manoeuvres (RM). ⋯ In hypersecretive patients, HFCWO significantly improved aeration of the dorsal lung region, without affecting ABGs. The application of RM did not provide any further improvements.

Randomized Controlled Trial
Effects of ventilation mode and manual chest compression on flow bias during the positive end- and zero end-expiratory pressure manoeuvre in mechanically ventilated patients: a randomised crossover trial.
To investigate the effects of ventilation mode and manual chest compression (MCC) application on the flow bias generated during positive end-expiratory pressure-zero end-expiratory pressure (PEEP-ZEEP) in mechanically ventilated patients. PEEP-ZEEP is an airway clearance manoeuvre with the potential to exceed the flow bias required to remove secretions. However, the ventilation mode applied during the manoeuvre has not been standardised. ⋯ http://www.ensaiosclinicos.gov.br/rg/RBR-223xv8/.
