In the Editorial by Steen, "Does Active Rescuer Ventilation Have a Place During Basic Cadiopulmonary Resuscitation?" which appeared in the November 27 issue of the journal (Circulation. 2007;116:2514-2516), the following correction should be made: On page 2514, right column, 6 lines from the top, "Tuscan, Ariz" should be changed to "Tucson, Ariz".
