Randomized Controlled Trial Comparative Study
Short-term effects of using pedometers to increase daily physical activity in smokers: a randomized trial.
In adults it is recommended that the minimum of 10,000 steps/day should be performed in order to consider an individual as active. The pedometer, a small device that counts steps, has been used to monitor and/or motivate physical activity in various populations. ⋯ Physically inactive smokers improve their daily physical activity level by using a simple tool (pedometer), and larger improvement occurs in subjects with the lowest levels of physical activity.

Randomized Controlled Trial
Effects of exercise training on pulmonary mechanics and functional status in patients with prolonged mechanical ventilation.
The functional status and outcomes in patients with prolonged mechanical ventilation (PMV) are often limited by poor endurance and pulmonary mechanics, which result from the primary diseases or prolonged time bedridden. We evaluate the impact of exercise training on pulmonary mechanics, physical functional status, and hospitalization outcomes in PMV patients. ⋯ Subjects with PMV in our RCC demonstrated significant improvement in pulmonary mechanics and functional status after exercise training. The application of exercise training may be helpful for PMV patients to improve hospitalization outcomes.

Randomized Controlled Trial
Effect of slow expiration with glottis opened in lateral posture (ELTGOL) on mucus clearance in stable patients with chronic bronchitis.
Slow expiration with glottis opened in lateral posture (ELTGOL, l'expiration lente totale glotte ouverte en infralatéral) has been used in clinical practice to improve mucus clearance from peripheral airways. The purpose of this crossover study was to evaluate the effect of ELTGOL on mucus clearance of right and left lungs, especially of peripheral lung areas, in stable patients with chronic bronchitis. ⋯ ELTGOL was efficient in increasing peripheral airway clearance in dependent lung of patients with chronic bronchitis, most of them with mild to moderate COPD.

Randomized Controlled Trial Comparative Study
Influence of 4 interfaces in the assessment of maximal respiratory pressures.
The measurement of maximal respiratory pressure (MRP) is a procedure widely used in clinical practice to evaluate respiratory muscle strength through the maximal inspiratory pressure (P(Imax)) and maximal expiratory pressure (P(Emax)). Its clinical applications include diagnostic procedures and evaluating responses to interventions. However, there is great variability in the equipment and measurement procedures. Understanding the impacts of the characteristics of different interfaces can augment the repeatability of this method and help to establish widely applicable predictive equations. The aim of this study was to evaluate the influence of 4 different interfaces on a subject's capacity to generate MRP and the impact of these interfaces on the repeatability of these measurements. ⋯ P(Imax) and P(Emax) values seem not to be influenced by the different interfaces studied, suggesting that patient comfort and availability of interfaces can be considered.

Randomized Controlled Trial Multicenter Study
Preventive use of noninvasive ventilation after extubation: a prospective, multicenter randomized controlled trial.
The effectiveness of noninvasive ventilation (NIV) after extubation in preventing post-extubation respiratory failure is still controversial. ⋯ Preventive use of NIV after extubation in patients who passed spontaneous breathing trial did not show benefits in decreasing extubation failure rate or the mortality rate.
