AbstractIntensive care subjects the critically ill patient to a multitude of stressors caused by the severity of illness and the use of invasive treatment modalities and medications. The ICU environment contributes significant stress of its own related to noise, light, 24-hour patient care, and other factors that disturb sleep. Consequently, various sleep pathologies may emerge or worsen in the ICU patient. Some sleep disorder symptomatology may be confused with serious neurologic complications of critical illness and lead to inappropriate testing or treatment, particularly in the patient who has narcolepsy. Given the high prevalence of sleep disorders in the general population, it is essential that the ICU practitioner attain an adequate knowledge of sleep and its disorders.
