Randomized Controlled Trial[A study of the value of high frequency chest wall oscillation in patients with acute exacerbation of chronic obstructive pulmonary disease].
To explore the safety and efficacy of high-frequency chest wall oscillation (HFCWO) in invasive mechanical ventilation patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). ⋯ HFCWO is very safe and comfortable in ventilated patients with AECOPD. It reduces the total mechanical ventilation time, but cannot improve the prognosis.

Effect of high-frequency chest wall oscillation versus chest physiotherapy on lung function after lung transplant.
The aim of this study is to compare the effects of chest physiotherapy (CPT) and high-frequency chest wall oscillation (HFCWO) on lung function in lung transplant recipients. ⋯ Preliminary results suggest that lung function (measured by Spo2/FiO2) improves with HFWCO after lung transplantation. Although dyspnea and PEF did not differ significantly between treatment types, HFCWO may be an effective, feasible alternative to CPT.

Review Meta AnalysisOscillating devices for airway clearance in people with cystic fibrosis.
Chest physiotherapy is widely prescribed to assist the clearance of airway secretions in people with cystic fibrosis. Oscillating devices generate intra- or extra-thoracic oscillations orally or external to the chest wall. Internally they create variable resistances within the airways, generating controlled oscillating positive pressure which mobilises mucus. Extra-thoracic oscillations are generated by forces outside the respiratory system, e.g. high frequency chest wall oscillation. ⋯ There was no clear evidence that oscillation was a more or less effective intervention overall than other forms of physiotherapy; furthermore there was no evidence that one device is superior to another. The findings from one study showing an increase in frequency of exacerbations requiring antibiotics whilst using an oscillating device compared to positive expiratory pressure may have significant resource implications. More adequately-powered long-term randomised controlled trials are necessary and outcomes measured should include frequency of exacerbations, patient preference, adherence to therapy and general satisfaction with treatment. Increased adherence to therapy may then lead to improvements in other parameters, such as exercise tolerance and respiratory function. Additional evidence is needed to evaluate whether oscillating devices combined with other forms of airway clearance is efficacious in people with cystic fibrosis.

Survival from out-of-hospital cardiac arrest depends largely on two factors: early cardiopulmonary resuscitation (CPR) and early defibrillation. CPR must be interrupted for a reliable automated rhythm analysis because chest compressions induce artifacts in the ECG. Unfortunately, interrupting CPR adversely affects survival. ⋯ Recently, researchers have proposed a new methodology to measure this impact. Moreover, new strategies for fast rhythm analysis during ventilation pauses or high-specificity algorithms have been reported. Our objective is to present a thorough review of the field as the starting point for these late developments and to underline the open questions and future lines of research to be explored in the following years.

Children with neurological impairment often suffer from insufficient airway secretion clearance, which substantially increases their respiratory morbidity. The goal of the study was to assess the clinical feasibility of high-frequency chest wall compression (HFCWC) therapy in neurologically impaired children with respiratory symptoms. ⋯ Regular HFCWC therapy may reduce the number of hospitalizations in neurologically impaired children.
