Treatment of Pulmonary Chemical-Warfare Injuries Supportive care For type 1: Early intubation and bronchodilators, sometimes inhaled corticosteroids, and antibiotics for documented secondary bacterial infection For type 2: Oxygen and positive-pressure ventilation (continuous positive airway pressure in conscious patients; positive end-expiratory pressure in ventilated patients), bronchodilators, and rarely corticosteroids It is important to treat the damage rather than the agent because some agents cause both type 1 and type 2 effects even at low doses, and high doses of either agent cause both types of damage.
