The 5th edition of the "Athletic Training Education Competencies" expanded the scope of knowledge and skill set of entry-level athletic trainers related to the domain of "Acute Care of Injuries and Illnesses." One of these major changes includes the introduction of adjunct airway techniques, such as oropharyngeal and nasopharyngeal airways and suction. Another new addition includes the use of pulse oximetry to assess oxygen saturation levels. The addition of these acute care knowledge and skill competencies were incorporated into the athletic training curriculum to reflect the National Athletic Trainers' Association's currently published position statement recommendations, as well as those in development. This article provides athletic training educators (ATE) with a resource on how to use and teach pulse oximetry within their educational programs. (Contains 7 tables and 1 figure.)
