Coma can occur at what blood alcohol level?

Coma can occur at what blood alcohol level?

• A. 300-350 mg%
• B. 350-399 mg%
• C. 400-600 mg%
• D. 600-800 mg%

Answer: (C)

High blood alcohol concentration produces progressively deeper CNS depression, and coma occurs when the depressant effects reach the brainstem and respiratory centers. The range of 400–600 mg per 100 mL (0.40–0.60% BAC) is the level at which patients commonly present in coma due to profound central nervous system suppression. At this level, airway protection and ventilation become critical concerns, and the person may be unresponsive with diminished respiratory drive and reflexes, requiring urgent medical intervention.
