We conducted a questionnaire survey of 346 pulmonary rehabilitation programs to determine the present utilization and potential value of these sites for promoting advance directive education for patients with chronic lung diseases. Responses were analyzed for all responding programs and for programs categorized by size. Eighty-two percent of the 218 responding programs discussed with patients prognostic information. ⋯ Larger programs were more likely to present information about patient prognosis (p = 0.0003) and advance directives (p = 0.021). We conclude that most of the responding pulmonary rehabilitation programs do not educate patients about advance directives but are willing to do so if supplied with appropriate teaching materials. Rehabilitation programs may be valuable sites for educating patients with chronic disorders about advance directives and promoting an improved patient-physician dialogue about these issues.

To study the effect of positive end-expiratory pressure (PEEP) on the decay of respiratory system compliance (Cpl,rs) due to low tidal volume (VT) ventilation in acute lung injury (ALI) patients. ⋯ A PEEP of at least 15 cm H2O was needed to prevent Cpl,rs decay. The progressive Cpl,rs loss we observed at lower PEEP probably reflects alveolar instability.
