SYMPTOMS OF CO POISONING
Initial carbon monoxide poisoning symptoms are similar to the flu with no fever and can include
dizziness, severe headaches, nausea, vomiting and disorientation. Everyone is susceptible but
experts agree that unborn babies, pregnant women, senior citizens and people with heart or
respiratory problems are especially vulnerable. If symptoms of carbon monoxide poisoning
are experienced seek medical attention immediately. CO poisoning can be determined by a
carboxyhemoglobin test.
THE FOLLOWING SYMPTOMS ARE RELATED TO CARBON MONOXIDE POISONING
AND SHOULD BE DISCUSSED WITH ALL MEMBERS OF THE HOUSEHOLD:
1. MILD EXPOSURE:
Slight headache, nausea, vomiting, fatigue (often described as “Flu-
like” symptoms).
2. MEDIUM EXPOSURE:
Severe throbbing headache, drowsiness, confusion, fast heart rate.
3. EXTREME EXPOSURE:
Unconsciousness, convulsions, cardio respiratory failure and death.
The above levels of exposure relate to healthy adults. Levels differ for those at high risk.
Exposure to high levels of carbon monoxide can be fatal or cause permanent damage and
disabilities. Many cases of reported carbon monoxide poisoning indicate that while victims are
aware they are not feeling well, they become so disoriented they are unable to save themselves
by either exiting the building, or calling for assistance. Also, young children and household pets
may be the first affected. Familiarization with the effects of each level is important.
