Randomized Controlled Trial Multicenter Study Clinical Trial
Mask proportional assist vs pressure support ventilation in patients in clinically stable condition with chronic ventilatory failure.
To compare the short-term physiologic effects of mask pressure support ventilation (PSV) and proportional assist ventilation (PAV) in patients in clinically stable condition with chronic ventilatory failure (CVF). ⋯ In resting, awake patients in clinically stable condition with CVF caused by either COPD or RCWD, noninvasive application of PAV, set at the patient's comfort, was not superior to PSV either in increasing VT and E or in unloading the inspiratory muscles. We failed to find any difference in patient/ventilator interaction between ventilatory modes.

Randomized Controlled Trial Multicenter Study Clinical Trial
Using quality of life to predict hospitalization and mortality in patients with obstructive lung diseases.
Condition-specific measures of quality of life (QOL) for patients with COPD have been demonstrated to be highly reliable and valid, but they have not conclusively been shown to predict hospitalization or death. ⋯ Lower QOL is a powerful predictor of hospitalization and all-cause mortality. Brief, self-administered instruments such as the SOLDQ may provide an opportunity to identify patients who could benefit from preventive interventions.
