Brief summary
Sleep investigation in respirator treated ICU patients: the importance of intensive environment. Sleep disturbances in the ICU seem to lead to development of delirium, prolonged ICU stay and increased mortality. The hypothesis of this study is: minimizing of disturbing factors in the ICU, such as noise, light, therapeutic and diagnostic procedures between 10 p.m. and 6 a.m. will improve sleep quality in respirator treated ICU patients. Methods: randomized interventional study. 48-hour polysomnographic sleep measurement acc. AASM's standard in 46 awake respirator treated patients: 24 hours under ordinary circumstances and 24 hours under the protocol 'Quiet in the room' between 10 p.m. and 6 a.m. after randomization.
Interventions
BEHAVIORALprotocol 'Quiet in the room'
Protocol 'Quite in the room' between 10 p.m. and 6 a.m. * nurse nearby * no visits after 10 p.m. * decreased alarm sound in ventilator and monitor * decreased light intensity * no unnecessary conversations around the patient * medication should be limited to max 1-2 times in this time period * no unnecessary therapeutic or diagnostic procedures in this time period * earplugs and sleep masks

Primary
| Measure | Time frame | Description |
|---|---|---|
| the number of arousals | per hour of sleep | arousals will be scored during the sleep periods and the index - arousals per hour of sleep - will be counted |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| total sleep time | 24 hours | total sleep time during 24 hour period |
| N1 sleep | 24 hours | N1 sleep stage will be scored during sleep periods (dag sleep/night sleep)and the percent of N1 sleep will be counted |
| N2 sleep | 24 hours | N2 sleep stage will be scored during sleep periods and the percent of N2 sleep will be counted |
| N3 sleep | 24 hours | N3 sleep stage will be scored during sleep periods and the percent of N3 sleep will be counted |
| REM sleep | 24 hours | REM sleep will be scored during sleep periods and the percent of REM sleep will be counted |
