Pulmonary toxicity nasal airway

A. Thermal and irritant effects include singed nasal hairs, carbonaceous material in the nose and pharynx, cough, wheezing, and dyspnea. Stridor is an ominous finding that suggests imminent airway compromise due to swelling in and around the larynx. Pulmonary edema, pneumonitis, and adult respiratory distress syndrome (ARDS) may occur. Intimation of steam is strongly associated with deep thermal injury but is not complicated by systemic toxicity.
