Which abbreviation corresponds to Carbon Monoxide?

Which abbreviation corresponds to Carbon Monoxide?

• A. CO
• B. CO2
• C. MDI
• D. CPAP

Answer: (A)

Chemical abbreviations for gases use a concise symbol that reflects the elements present. Carbon monoxide is represented by CO, a two-letter symbol from carbon and oxygen in a 1:1 ratio. Carbon dioxide would be CO2, which has an extra oxygen atom and is a different molecule entirely. In prehospital care, recognizing CO is crucial because it binds hemoglobin with high affinity, reducing oxygen delivery to tissues. Treatment focuses on providing 100% oxygen to displace CO, with hyperbaric oxygen considered in certain severe cases. Other options refer to devices or therapies not related to chemical symbols (for example, a Metered Dose Inhaler and CPAP).
