Definition and Causes
Smoke inhalation is the leading cause of death related to fire. Victims of smoke inhalation suffer a combination of injuries
from airborne particles, burns to the throat and lungs, and chemical poisoning.
The combustion of plastics, textiles, and other synthetic materials produces a highly toxic mix of cyanide and carbon monoxide.
bind to hemoglobin in red blood cells and block their capacity to carry oxygen to cells and tissues.
Inhaling even small amounts of fire smoke can be fatal. Serious and sometimes permanent neurological effects may be delayed
days or weeks after acute poisoning.

Treatment with Hyperbaric Oxygen Therapy
Hyperbaric oxygen therapy (HBOT) is indicated for the emergency treatment of carbon monoxide poisoning complicated by cyanide
poisoning after smoke inhalation. HBOT dissolves additional oxygen in the blood plasma and has been shown to work effectively
alone and in combination with hydroxocobalamin (Cyanokit) and other cyanide antidote kits.
The emergency treatment of smoke inhalation offers perhaps the single best reason for the healthcare community to demand
24/7 access to hyperbaric chambers across the US. Cyanide, carbon monoxide, inhaled particulates, and thermal injuries
together require speedy action to save the lives of firefighters and other fire victims. The clinical evidence for HBOT
may not be as strong for nonfire cyanide poisoning as for nonfire carbon monoxide poisoning, but the benefits of oxygen
are well established. As
puts it: “Oxygen and sodium thiosulfate are the most widely accepted cyanide antidotes…. The mechanism of action of oxygen
as a cyanide antidote is unclear, but it potentiates the effect of other antidotes. When used in the setting of smoke
inhalation, it is also therapeutic for CO poisoning. Thus, high concentrations of oxygen should be promptly delivered.”
Ongoing surveillance projects and prospective trials may bolster the clinical case for HBOT in the routine treatment of
