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:
MILD EXPOSURE: Headaches, fatigue, drowsiness, shortness of breath, “flu”-like symptoms
(without fever), and impaired motor functions (like difficulty walking or problems with balance);
MEDIUM EXPOSURE: Dizziness, nausea and vomiting, chest pain, poor vision, difficulty
thinking;
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. When flu-like symptoms with fever are experienced, ensure that the possibility of CO
poisoning is not automatically ruled out. Many cases of reported carbon monoxide poisoning
indicate that while victims are aware they are not 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.
