Abstract
- Carbon dioxide (CO2) poisoning is rare, but its clinical features of acute exposure include cardiovascular, respiratory, neurologic and metabolic aspects. CO2 can also have a direct toxicological effect. At very high concentrations (>9%), CO2 induces respiratory depression and narcotic-like effects on the central nervous system. Especially, acute poisoning from dry ice is caused by CO2 gas inhalation and asphyxiation, and may impose excess load on the myocardium. This case was an acute CO2 poisoning from dry ice gas inhalation. In spite of an initial severe status, the male patient rapidly improved with no complications following the application of highly concentrated oxygen and fluid therapy.
