Randomized Controlled TrialEffectiveness of treatment with high-frequency chest wall oscillation in patients with bronchiectasis.
High-frequency airway clearance (HFCWC) assist devices generate either positive or negative trans-respiratory pressure excursions to produce high-frequency, small-volume oscillations in the airways.HFCWC can lead to changes in volume of 15-57 ml and in flow up to 1.6 L/s, which generate minimal coughing to mobilize secretions. The typical treatment lasts 20-30 minutes, and consists of short periods of compression at different frequencies, separated by coughing.The aim of this study was to find the more efficacious treatment in patients with bronchiectasis: traditional techniques of chest physiotherapy (CPT) versus high frequency oscillation of the chest wall in patients with bronchiectasis. ⋯ The HFCWO technique provides an improvement both in pulmonary function and quality of life related parameters in patients with chronic hypersecretive disease. Since those patients need daily airway clearance, this treatment should be included among the principal options in chest physiotherapy. The study was registered as ChiCTR-TRC-12002134 at http://www.chictr.org.

Effect of continuous compression and 30:2 cardiopulmonary resuscitation on cerebral microcirculation in a porcine model of cardiac arrest.
The effect of rescue breathing on neurologic prognosis after cardiopulmonary resuscitation (CPR) is controversial. Therefore, we investigated the cerebral microcirculatory and oxygen metabolism during continuous compression (CC) and 30:2 CPR (VC) in a porcine model of cardiac arrest to determine which is better for neurologic prognosis after CPR. ⋯ Inconsistency of systemic circulation and cerebral microcirculation with regard to blood perfusion and oxygen metabolism is common after CPR. No significant differences in cortical blood flow and oxygen metabolism were found between the CC-CPR and VC-CPR groups after ROSC.

Case Reports
Prolonged high-frequency oscillatory ventilation in tubercular multifocal cystic lung disease.
Multifocal cystic lung disease in infants is most commonly congenital, and is managed surgically with perioperative mechanical ventilation. Multifocal cystic lung disease in infants may be due to tuberculosis. We report a young infant with tubercular multifocal cystic lung disease and respiratory failure. ⋯ Subsequent chest imaging showed progression to multifocal cystic lung disease. The ventilation mode was changed to high-frequency oscillatory ventilation (HFOV) due to persistent CO(2) retention in the presence of cystic lung disease. The cystic lung disease reversed with antitubercular treatment and prolonged HFOV with slow wean.

Comparative StudyFour-stage teaching technique and chest compression performance of medical students compared to conventional technique.
To compare the 2-stage and 4-stage basic life support teaching technique. The second aim was to test if students' self-evaluated knowledge was in accordance with their actual knowledge. ⋯ The 4-stage teaching technique does not significantly improve the quality of chest compressions. The students' self-evaluation of their performance after the course was too high.
