Step-by-step explanation:
Early Symptoms of Carbon Monoxide Poisoning
One of the early symptoms of carbon monoxide poisoning is headache. Other symptoms may include dizziness, weakness, and nausea. Carbon monoxide is a colorless, odorless gas which has a strong affinity for hemoglobin, preventing oxygen from being transported effectively throughout the body. Exposure can lead to severe health issues such as confusion, loss of consciousness, and even death in extreme cases. Treatment typically involves the administration of 100% oxygen to speed up the elimination of carbon monoxide from the bloodstream.
