Effects of Light and Sound Modification on Sleep Quality and Circadian Rhythm in the MICU Patients

Effects of Light and Sound Modification on Sleep Quality and Circadian Rhythm in the Medical Intensive Care Unit Patients

This study will investigate the effectiveness of light and sound modification in improving sleep qualit , and circadian rhythms in MICU patients with Mechanical Ventilation in Taiwan.

Hypothesis:

1. The sleep quality in intervention group is significant improving than usual-care group at Day 1 (after the first intervention), Day 2 (after the second intervention), and Day 3 (after the third intervention).
2. The circadian rhythm in intervention group is significant improving than usual-care group at Day 1 (after the first intervention), Day 2 (after the second intervention), Day 3 (after the third intervention).

The subjects were divided into experimental and control groups. And the improving quality of sleep intervention was provided only in experimental group. In the experimental group，the patients used earplugs and eye masks during nighttime sleep. In the control group, the received routine intensive care.

Inclusion Criteria:
