In the article, “Multi-Agency, Prehospital Evaluation and the Pharyngeo-Tracheal Lumen (PTL) Airway,” by McMahan, Ornato, Racht, and Cameron, on pages 13–16, in January–March 1992 issue of Prehosptal and Disaster Medicine, there was a typographical error regarding the number of patients in the study population. On page 13, the Methods section of the Abstract incorrectly states that 1,647 adult patients participated in the study. The actual study population was 167 patients. We regret the error.
