It is underlying primary cause of death for victims of fires.The inhalation or exposure to hot gaseous products of combustion can cause serious respiratory complications.. Upper airway is typically affected (except in steam inhalation which can affect sub-glottic airway) Inhalation injuries are mediated by chemical lung injury (not typically heat) Results in large volume fluid influx into the lungs Signs: Findings suggestive of Smoke Inhalation Patients with inhalation injuries generally require more fluid resuscitation (closer to 4mL x %BSA x kg) however the extent of injury is impossible to quantify accurately, so instead, end-organ perfusion should be monitored carefully to help guide management. The associated complications vary with the level of injury and are also affected by intubation, infection and chronic inflammation. You may find one of our health articles more useful.

The prevention of smoke injury is largely the prevention of fire but, if it does occur, then early warning is necessary. Smoke inhalation should be diagnosed by the presence of an elevated carboxyhaemoglobin level. The clinical symptoms and prognosis of smoke inhalation injury are often exacerbated by additional burn injury or bacterial infection (such as pneumonia).
