Short-term memory can also be affected. These effects usually improve over time, but may be permanent. CO poisoning is not contagious. However, people who were near the affected person may also have been exposed to the carbon monoxide. The first treatment for CO poisoning is to remove the person from the CO and into fresh air.
Further treatment depends on the extent of poisoning.
Oxygen through a tight fitting mask, intravenous fluids, as well as medications including steroids may also be required. A ventilator , or artificial breathing machine, may be required if the lungs have been affected. At times, sedatives may also be used to decrease any excitability caused by the CO build-up in the body. Side effects will depend on the treatments used. For instance, steroids may cause irritability , weight gain, or stomach upset.
