While most studies in the medical literature that indicate music as an intervention may recognize its impact and capacity to decrease pain perception, anxiety, and/or its role in the regulation of cardiac and respiratory function in ICU patients, no identifiable studies have implemented entrained live music therapy protocols into clinical trials. Music therapy treatment is a non-pharmacological intervention that is individually tailored to the patient's needs and focuses on the assessment and intervention of a specific music application that is provided by a certified music therapist. Entrained music therapy focuses on a dynamic interaction between the patient and music therapist in which the music therapist attempts to promote relaxation and comfort through the patient's identified Song of Kin (SOK). This study measures the effects of live music therapy entrained to the vital signs of adult patients on duration of mechanical ventilation.
