- Suspect smoke inhalation in anyone involved in a fire within a closed space or with a history of loss of consciousness.
- May cause direct injury to the upper (supraglottic) airway structures
- May cause chemical/irritant effect to lower airway structures
- May cause systemic toxicity from inhaled substances
- Direct heat injury from heated gases/smoke:
- Limited to supraglottic structures because of the heat-dissipating properties of the upper airway
- Irritant effect from smoke components
- Systemic toxicity from inhaled cellular toxins:
- Carbon monoxide
- Hydrogen cyanide
Inhalation of steam can be rapidly fatal:
- Steam has ∼4,000 times the heat-carrying capacity of hot air.
- Can rapidly cause obstructive glottic edema, thermally induced tracheitis, and hemorrhagic edema of the bronchial mucosa
