carbon monoxide binds to hemoglobin instead of oxygen as it has 280 times greater affinity for hemoglobin than oxygen.carbon monoxide levels must be directly meausred (not calculated) and are measured as carboxyhemoglobin on the CCTC GEM.carbon monoxide toxicity contributes to the metabolic acidosis by limiting oxygen transport to tissues.pulse oximetry cannot distinguish between oxyhemoglobin and carboxyhemoglobin, resulting in falsely elevated SpO 2 reading.PaO 2 may be elevated with a low oxygen saturation (carbon monoxide preferentially combines with hemoglobin instead of oxygen).Standard approach to trauma is followed including assessment for C-spine and head injuries, pulmonary and abdominal trauma, fractures etc.Morbidity and mortality increases with increased BSA % of burn, in the very young or very old, and when pre-existing diseases are present such as cardiovascular, renal or pulmonary disorders.
