Psychophysiologic responses of mechanically ventilated patients to music: a pilot study

Abstract: Background Although mechanically ventilated patients experience numerous stressors, they have not been included in music therapy stress reduction and relaxation studies. Objective To examine selected psychophysiologic responses of mechanically ventilated patients to music. Methods A two-group experimental design with pretest, posttest, and repeated measures was used. Twenty mechanically ventilated patients were randomized to a music-listening group or a nonmusic (headphones only) group. Physiologic dependent measures--heart rate and rhythm, respiratory rate, systolic and diastolic blood pressure, oxygen saturation, and airway pressure--were collected at timed intervals. Psychologic data were collected before and after intervention using the Profile of Mood States. Results Using repeated measures analysis of variance, results for heart rate and respiratory rate over time and over time between groups were significant. Between-group differences were significant for respiratory rate. Significant differences were found via t test for the music group's Profile of Mood States scores. No adverse cardiovascular responses were noted for either group. Conclusions Data indicated that music listening decreased heart rate, respiratory rate, and Profile of Mood States scores, indicating relaxation and mood improvement.

Clinical staging of chronic rejection in lung transplantation using home spirometry

Abstract: Clinical staging of chronic rejection in transplanted lungs has been evaluated in a group of transplant recipients using a paperless, electronic spirometer/diary instrument for home monitoring. Five of 60 subjects doing home monitoring were diagnosed with chronic rejection. Clinic and home spirometry variables were used in the staging algorithm to determine the onset and rate of clinical decline related to the rejection. Clinic and home FEV1 provided comparable onset and rates of decline; home FEF/sub 25%-75%/ detected onset from 65-477 days earlier than either FEV1 measure, and was more sensitive to declining function than FEV1. Detection of chronic rejection can be achieved with the home monitor, and home FEF/sub 25%-75%/ provides a new indicator that should be considered in future staging systems.
