Carbon monoxide (CO) is a colourless, odourless gas resulting from the burning of hydrocarbons such as in a poorly functioning furnace or vehicle emissions. O can bind with hemoglobin to form
carboxyhemoglobin. Hemoglobin's affinity for CO is 200 times greater than its affinity for oxygen
The initial symptoms of carbon monoide poisoning are flu-like, such as dizziness, headache and
vomiting However, when left unchecked. CO poisoning can result in unconsciousness, loss of blood
flow to the vital organs and eventually death
