CO poisoning may occur sooner in those most susceptible:
- Young children
- The elderly
- People with lung or heart disease
- People at high altitudes, or those who already have elevated CO blood levels, such as smokers.
- Also, CO poisoning poses a special risk to fetuses.
- CO poisoning can be reversed if caught in time. But even if you recover, acute poisoning may result in permanent damage to the parts of your body that require a lot of oxygen such as the heart and brain. Significant reproductive risk is also linked to CO.
