Summary
Critically ill patients with obstructive sleep apnea (OSA) face risks of prolonged apneas and death. Documented OSA in two patients led to EEG changes indicating cerebral hypoxemia, causing encephalopathy in one and death in the other.
Area of Science:
- Critical Care Medicine
- Neurology
- Sleep Medicine
Background:
- Obstructive sleep apnea (OSA) is common in critically ill patients.
- Increased arousal threshold in OSA may lead to prolonged sleep apneas.
Observation:
- Two cases of polysomnographically confirmed OSA in critically ill patients are presented.
- Patients exhibited electroencephalogram (EEG) changes indicative of cerebral hypoxemia.
Findings:
- Obstructive sleep apnea (OSA) was linked to EEG abnormalities suggesting cerebral hypoxemia.
- One patient experienced transient encephalopathy, while the other succumbed to the condition.
Implications:
- This highlights a potential mechanism linking OSA to adverse neurological outcomes in critical illness.
- Early recognition and management of OSA may be crucial for improving outcomes in this patient population.
