Poisoning from fire smoke - Poisoning from carbon monoxide, cyanide, irritant and suffocating gases

Medium urgency
-Moderately severe
Smoke inhalation injury varies depending on the material that burns (various toxic gases), the temperature of the smoke, the ambient oxygen, the time and distance to the site, the residual soot, etc. It causes irritation and burns to the respiratory system and toxicity of other organs in the body. A blood test helps to determine the toxin causing the injury and to see the progression of the intoxication. It is always a life-threatening emergency and the emergency medical service (ambulance) or fire brigade must be contacted, given that the earlier the treatment is provided, the better the prognosis will be. It is necessary to administer oxygen, treat the bronchospasm/edema and assess orotracheal intubation, stabilize circulation and consider using hydroxocobalamin as an antidote for carbon monoxide. Treatment must be based on clinical severity and NEVER on the test results.
