Toxin-induced Respiratory Distress.

Abstract
This article describes the impact of various toxic substances on the airway and pulmonary system. Pulmonary anatomy and physiology provide the basis for understanding the response to toxin-induced injury. Simple asphyxiants displace oxygen from the inspired air. Respiratory irritants include water-soluble and water-insoluble compounds. Several inhaled agents produce direct airway injury, which may be mediated by caustic, thermal, and hydrocarbon exposures. Unique pulmonary toxins and toxicants are discussed, as well as inhaled toxin mixtures. Several inhaled toxins may also impair oxygen transport. The pulmonary system may also provide a mechanism for systemic toxin delivery on respiratory exposure.
