Randomized Controlled Trial Comparative Study
Volume-targeted versus pressure-targeted noninvasive ventilation in patients with chest-wall deformity: a pilot study.
Long-term noninvasive ventilation (NIV) is an effective treatment for patients with chronic respiratory failure due to chest-wall deformity, but it is unknown if the time required for the patient to adjust to long-term NIV depends on whether the NIV is volume-targeted or pressure-targeted. ⋯ There was no significant difference in days needed to successfully establish volume NIV versus pressure NIV in patients with chest-wall deformity. However, two patients switched successfully from volume NIV to pressure NIV, which suggests that they preferred pressure NIV.

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.
