What are some of the symptoms of carbon monoxide poisoning?

Unfortunately, the symptoms are easily overlooked because they are often flulike. With mild exposure, most people experience headaches, fatigue and nausea. Medium exposure can cause a severe throbbing headache, drowsiness, disorientation, confusion and an accelerated heart rate. Extreme exposure can lead to unconsciousness, convulsions, cardiorespiratory failure, coma and possibly death.
