Revision as of 12:42, 12 January 2016
Background
- increased CO2 in the blood leading to depressed mental status
- most commonly seen in acute exacerbations of obstructive pulmonary diseases
- can also be seen in SCUBA divers
Clinical Features
- headache, confusion, lethargy, propensity for arrhythmias, seizure/coma/death
Differential Diagnosis
- drug intoxication
- encephalopathy (renal, hepatic, hypertensive)
- ICH
- seizure
Diagnosis
- ABG
Management
- hyperventilation with either NIPPV or intubation/mechanical ventilation depending on severity and patient's mental status
Disposition
- admission to a monitored setting
