Intensive care unit (ICU) patients are known to experience severely disturbed sleep, with 
possible detrimental effects on short- and long- term outcomes. Investigation into the exact 
causes and effects of disturbed sleep has been hampered by cumbersome and time consuming 
methods of measuring and staging sleep. We introduce a novel method for ICU depth of sleep 
analysis, the ICU depth of sleep index (IDOS index), using single channel 
electroencephalography (EEG) and apply it to outpatient recordings. A proof of concept is 

shown in non-sedated ICU patients.
