Carbon monoxide causes mild effects that are often mistaken for the flu. Therefore, knowing what to look out for is the first step in combating carbon monoxide poisoning. They include:
- Visual problems
- Pains in the chest or stomach
- Erratic behaviour
- Loss of consciousness
How does carbon monoxide affect people?
Effects can vary considerably, depending on a person’s age, overall health, and the concentration and length of exposure. If inhaled at damaging levels, carbon monoxide can cause:
- Breathing difficulties
- Impaired judgment and memory
- Damage to the nervous system
- Cardiac trauma
- Brain damage
Long-term effects caused by CO exposure
However, effects produced by exposure to CO are mostly reversible. However, extensive and significant overexposure can cause permanent damage, and is most likely to occur in the nervous system. These effects can include:
- Loss of memory
- Acute renal failure
- Mental deterioration
- Learning disabilities
- Instability when walking
