Carbon monoxide (CO) poisoning can be confused with flu, food poisoning or other illnesses. Symptoms from low-level or prolonged exposure include:
• Headache, nausea, vomiting, muscle pain, fatigue, numbness, tingling and vertigo.
• Cognitive/memory impairment, such as attention problems, multi-tasking problems, word-finding problems, short-term memory problems, verbal and/or visual deficits.
• Emotional/personality effects, such as irritability, anxiety, lack of motivation, temper, loss of interest and sleep disturbance.
• Sensory and motor dysfunction, such as blurry or double vision, buzzing in the ears, decreased coordination and trouble speaking, eating and swallowing.
• Gross neurological impairment, such as seizures, inability to speak, balance problems and tremors.
PREVENTION
• Install a carbon monoxide alarm to warn of dangerous levels of CO.
• Have your heating system inspected by a qualified contractor before you turn your furnace on each fall.
