Physiological Effects of Smoke Inhalation:

• Thermal Injury:
  • Direct upper airway damage from heated air or steam.
  • Leads to swelling, inflammation, and possible airway obstruction.
• Chemical Irritation:
  • Causes bronchospasm, mucus plugging, and inflammation in the lower airways.
  • Increases capillary permeability, potentially causing pulmonary edema.
• Systemic Toxicity:
  • Primarily involves carbon monoxide and cyanide poisoning.
