Sleep disordered breathing is the most common sleep disease, and obstructive sleep apnea is the most common disorder among the sleep disordered breathing. Comorbid conditions in critically ill patients (mechanically ventilated) in ICU may effect both the primary reason of ICU stay and outcome.

Obstructive sleep apnea is not one of the known comorbid conditions among the patients who are treated in ICU. Diabetes mellitus, hypertension and other respiratory diseases rather than sleep disordered breathing are known conditions, however, OSA are not among those. Prevalence of sleep disordered breathing varies from 10% to 20% in mechanically ventilated patients. Sleep disordered breathing is one of the main reasons for hypercapneic respiratory problems, therefore it is important to be aware of sleep disordered breathing in mechanically ventilated patients, otherwise there may be delay in extubation or discharge from ICU.

The prevalence of OSA is 10% in women, and 15-20% in men. Few retrospective studies reported the prevalence of OSA as 10 to 20%. There are many people undiagnosed with OSA. Therefore previously reported prevalence of OSA in mechanically ventilated patients don’t reflect the real prevalence. Prospectively well-designed new studies can report the real prevalence of OSA in mechanically ventilated patient.
