ABSTRACT Although mechanically ventilated patients experience numerous stressors, they have not been included in music therapy stress reduction and relaxation studies.
To examine selected psychophysiologic responses of mechanically ventilated patients to music.
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.
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.
Data indicated that music listening decreased heart rate, respiratory rate, and Profile of Mood States scores, indicating relaxation and mood improvement.

    ABSTRACT: Mechanical ventilation (MV) is a life-saving measure and supportive modality utilized to treat patients experiencing respiratory failure. Patients experience pain, discomfort, and anxiety as a result of being mechanically ventilated. Music listening is a non-pharmacological intervention used to manage these psychophysiological symptoms associated with mechanical ventilation. The purpose of this secondary analysis was to examine music preferences of 107 MV patients enrolled in a randomized clinical trial that implemented a patient-directed music listening protocol to help manage the psychophysiological symptom of anxiety. Music data presented includes the music genres and instrumentation patients identified as their preferred music. Genres preferred include: classical, jazz, rock, country, and oldies. Instrumentation preferred include: piano, voice, guitar, music with nature sounds, and orchestral music. Analysis of three patients' preferred music received throughout the course of the study is illustrated to demonstrate the complexity of assessing MV patients and the need for an ongoing assessment process.

    ABSTRACT: Background: Along history, music has been used in a variety of ways for therapeutic purposes and has long been recognized for its physiological and psychological effects. Music listening can be an effective nursing intervention, to enhance relaxation, provide distraction, and reduce pain. Objectives: The aims of this study were to identify changes produced by different musical stimuli in blood pressure (BP), heart rate (HR), respiratory rate (RR), and oxygen saturations (SpO2) and to verify the influence of music listening on patients' facial expressions with severe cerebral damage. Method: A quasiexperimental study was performed in 26 patients with severe cerebral damage, divided into control and case groups. Patients belonging to the case group were exposed to musical stimuli, radio, classical relaxing music (CRM), and relaxing music with nature sounds (RMNS). Patients were evaluated by measuring vital signs before and after exposure to each musical stimulus, as were the patients within the control group. Patients in the control group were exempt from any musical stimulus. Facial expressions were observed in each patient within the case group during the intervention. Results: The results show that radio produced a slight increase in systolic BP, HR, RR, and SpO2. The CRM induced a decrease of RR and an increase of SpO2 and also produced alterations of the facial expression. When RMNS was played, a decrease was displayed in BP, HR, and RR and an increase was displayed in SpO2. Alterations in facial expression were displayed in each patient. Conclusions: The results of the study suggest that the application of musical stimuli such as CRM and RMNS can be used to provide a state of relaxation in patients with severe cerebral damage.

    ABSTRACT: Music is an ideal intervention to reduce anxiety and promote relaxation in critically ill patients. This article reviews the research studies on music-listening interventions to manage distressful symptoms in this population, and describes the development and implementation of the Music Assessment Tool (MAT) to assist professionals in ascertaining patients' music preferences in the challenging, dynamic clinical environment of the intensive care unit (ICU). The MAT is easy to use with these patients who experience profound communication challenges due to fatigue and inability to speak because of endotracheal tube placement. The music therapist and ICU nursing staff are encouraged to work collaboratively to implement music in a personalized manner to ensure the greatest benefit for mechanically ventilated patients.
