No text entered.

Reporting Groups
Patient-directed Music Patients select preferred music for listening through headphones whenever they like for as long as they like whenever feeling anxious, desire some rest and quiet time, or for listening enjoyment while mechanically ventilated in the ICU.
Headphones Noise-canceling headphones only (no music) are applied by the patient to block out noise/sound in the ICU whenever desired.
Usual Care Patients receive usual care for the ICU and are encouraged to self-initiate rest periods twice daily.

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Overall limitations of the trial include the challenges of obtaining informed consent from patients' themselves. Many times patients were too sedated or not alert enough to participate in the consent process.
