Randomized Controlled Trial Comparative StudyEffect of high-frequency chest wall oscillation on pulmonary function after pulmonary lobectomy for non-small cell lung cancer.
We examined the feasibility of high-frequency chest wall oscillationtherapy in immediate postoperative lung recruitment after pulmonary lobectomy for non-small cell lung cancer compared to conventional chest physiotherapy. ⋯ High-frequency chest wall oscillation therapy after pulmonary lobectomy resulted in significantly improved immediate postoperative pulmonary function recovery compared to conventional physiotherapy, without any significant adverse effects. These results suggest that high-frequency chest wall oscillation therapy may be a valuable tool in the postoperative care of non-small cell lung cancer patients with lobectomy.

Clinical Trial
Computerised lung sound monitoring to assess effectiveness of chest physiotherapy and secretion removal: a feasibility study.
To explore the feasibility of computerised lung sound monitoring to evaluate secretion removal in intubated and mechanically ventilated adult patients. ⋯ Computerised lung sound monitoring in this small group of patients demonstrated a two-fold decrease in lung sound amplitude following chest physiotherapy. Subgroup analysis also demonstrated decreasing trends in lung sound amplitude in the group of 'loud' lungs following chest physiotherapy. Due to the small sample size and large SDs with high variability in the lung sound amplitude measurements, significance testing was not reported. Further investigation is needed in a larger sample of patients with more accurate measurement of sputum wet weight in order to distinguish between secretion-related effects and changes due to other factors such as airflow rate and pattern.

Addition of a video camera system improves the ease of Airtraq(®) tracheal intubation during chest compression.
Recent resuscitation guidelines for cardiopulmonary resuscitation emphasize that rescuers should perform tracheal intubation with minimal interruption of chest compressions. We evaluated the use of video guidance to facilitate tracheal intubation with the Airtraq (ATQ) laryngoscope during chest compression. Eighteen novice physicians in our anesthesia department performed tracheal intubation on a manikin using the ATQ with a video camera system (ATQ-V) or with no video guidance (ATQ-N) during chest compression. ⋯ In contrast, all participants successfully secured the airway with the ATQ-V, with or without chest compression. Concurrent chest compression increased the time required for intubation with the ATQ-N (without chest compression 14.8 ± 4.5 s; with chest compression, 28.2 ± 10.6 s; P < 0.05), but not with the ATQ-V (without chest compression, 15.9 ± 5.8 s; with chest compression, 17.3 ± 5.3 s; P > 0.05). The ATQ video camera system improves the ease of tracheal intubation during chest compressions.

Randomized Controlled Trial Comparative Study
A randomized trial of conventional chest physical therapy versus high frequency chest wall compressions in intubated and non-intubated adults.
Conventional chest physical therapy (CCPT), applied by therapists using cupped hands to perform percussion, is commonly used in hospitalized adults. However, increased work load demands and occupational health concerns (eg, carpal tunnel syndrome) limit the overall utilization of this therapy. Therefore, we conducted a study to compare the overall effectiveness of CCPT to high-frequency chest wall compressions (HFCWC) applied via a vibratory vest. ⋯ This study was inadequately powered for the primary outcome of interest and hence we cannot make recommendations on the preferential use of HFCWC or CCPT for intubated and non-intubated adult patients. HFCWC was associated with statistically better comfort scores. (ClinicalTrials.gov registration NCT00717873.).
