ABSTRACT
Carbon monoxide (CO) poisoning is a serious emergency that may result with death in our country. When CO is inhaled, it connects with hemoglobin and forms carboxyhemoglobin, which impairs oxygen transport and metabolism. In acute cases of smoke inhalation, CO and cyanide intoxication are associated with. A 35-year-old male patient weighing 90 kg was evaluated with a diagnosis of acute smoke inhalation from burns caused by fire in the office. We applied the recommended treatment modalities of up to three sessions per day for the CO intoxication patient admitted to our clinic. He was an acute smoke inhalation case exposed to long-term CO poisoning due to the intervention of a delayed fire. Applying early and high doses of HBO treatment reduces the possibility of sequels.
