English: Plate II from An Atlas of Gas Poisoning by the American Red Cross and Medical Research Committee (American Red Cross, 1918).

Plate title: "Blue type of asphyxia from phosgene poisoning, with intense venous congestion." Text begins: "History of case. Drawing made early on second day after gassing; when there was copious frothy sputum, frequent cough, and hurried shallow respiration of 40 to 48 with temperature of 101° and pulse 100. The patient was bled 15 ozs. and oxygen added to the air that he breathed. He soon made a complete recovery. ..."

The American Red Cross published this guide for the American Expeditionary Force in World War I, sometimes called the "chemists’ war." The chromolithograph plates of characteristic injuries were intended to help inexperienced officers identify the type of gas used in attacks.
