Why Use an Oxygen Mask After a Fire

In addition to the potential for burn injuries, exposure to smoke inhalation is a common cause of injury after fires. There are several mechanism of injury after smoke inhalation. Treatment with oxygen is often the first therapy administered to the victim.

  1. Effects of Hot Smoke

    • Breathing in hot smoke burns the throat and airways. This leads to swelling and a narrowing of the windpipe and limits the flow of air.

    Chemical Inhalation

    • Burning of various products in fires leads to the release of poisonous chemicals such as hydrogen chloride, cyanide, carbon monoxide and sulfur dioxide. These can lead to further damage and swelling of the airways restricting airflow.

    Delayed Effects

    • Unfortunately, the effects of smoke inhalation injury may not be evident for up to 24 hours. This delayed presentation makes early assessment and treatment necessary after a fire.

    Oxygen Treatment

    • Oxygen is administered through a face mask immediately after a fire. This provides the victim with additional oxygen and makes breathing with the injured airways easier.

    Oxygen in the Blood

    • Inhalation of poisons such as carbon monoxide also may displace oxygen from the red blood cells worsening the effects of hypoxia. Oxygen administration can help reverse this process.
