Diagnosis of inhalation injury is not always straightforward, owing to poorly sensitive screening tests and, in many cases, the delay in manifestation of clinically significant symptoms until 24-72 hours after injury. In treatment of smoke inhalation, the most immediate concern is reversing cellular asphyxia and carbon monoxide (CO) and CN toxicity (see Treatment).
