AIS — Abbreviated Injury Scale for Inhalation Injury (Lung Injury Score)

The Abbreviated Injury Scale (AIS) for Inhalation Injury / Lung Injury Score (LIS) characterizes pulmonary damage from smoke/thermal inhalation injury in burn patients. Inhalation injury is classified by injury level: upper airway (supraglottic), lower airway (subglottic/tracheobronchial), and parenchymal (pulmonary). Combined with patient age and burn surface area (TBSA), it determines intubation need, ventilator management strategy, and prognosis. The diagnosis of inhalation injury is made clinically and bronchoscopically.
