Randomized Controlled Trial
Chair-sitting exercise intervention does not improve respiratory muscle function in mechanically ventilated intensive care unit patients.
Chair-sitting may allow for more readily activated scalene, sternocleidomastoid, and parasternal intercostal muscles, and may raise and enlarge the upper thoracic cage, thereby allowing the thoracic cage to be more easily compressed. ⋯ Six days of chair-sitting exercise training did not significantly improve respiratory muscle function in mechanically ventilated patients.

Randomized Controlled Trial
Evaluation of an alternative chest physiotherapy method in infants with respiratory syncytial virus bronchiolitis.
We proposed a new chest physiotherapy (CPT) secretion clearance method to treat respiratory syncytial virus bronchiolitis in infants. Our new CPT method consists of 15 prolonged slow expirations, then 5 provoked cough maneuvers. ⋯ Our new CPT method showed short-term benefits to some respiratory symptoms of bronchial obstruction in infants with acute respiratory syncytial virus bronchiolitis.

Randomized Controlled Trial
Remifentanil improves breathing pattern and reduces inspiratory workload in tachypneic patients.
Properly titrated opiates decrease respiratory rate but do not affect tidal volume or induce respiratory acidosis. ⋯ Remifentanil improved respiratory pattern and decreased inspiratory muscles effort in patients with tachypnea or rapid shallow breathing, but did not affect oxygenation or sedation. Though the acid-base balance did not show clinically relevant changes on average, we cannot exclude the possibility that remifentanil might prolong weaning in hypercapnic patients.

Randomized Controlled Trial Comparative Study
Tracheal secretion management in the mechanically ventilated patient: comparison of standard assessment and an acoustic secretion detector.
Standard indications for endotracheal suctioning are often based on clinical judgment on the deterioration of the patient's condition, and/or routine suctioning. TBA Care is a secretion detector that analyses airway sounds and indicates the need for suctioning. ⋯ TBA Care seems to give valid and timely indications for suctioning, anticipating clinical deterioration due to secretion retention and reducing unnecessary suctionings. (ClinicalTrials.gov registration NCT00932776.).

Randomized Controlled Trial
Pilot study of a new device to titrate oxygen flow in hypoxic patients on long-term oxygen therapy.
The O(2) Flow Regulator (Dima, Bologna, Italy) is a new automated oxygen regulator that titrates the oxygen flow based on a pulse-oximetry signal to maintain a target S(pO(2)). We tested the device's safety and efficacy. ⋯ The O(2) Flow Regulator may be a safe and effective alternative to manual oxygen titration during exercise in hypoxic patients. It provided stable S(pO(2)) and avoided desaturations in our subjects.
