Oxygen is one of the most frequently administered interventions in EMS, yet its potential harms are often under-recognized. This session reframes oxygen as a vasoactive medication with dose-dependent effects and examines current evidence surrounding hyperoxia and patient outcomes.
Attendees will explore the physiologic effects of hyperoxia and how excessive oxygen administration can impact coronary, cerebral, and systemic perfusion. The presentation will discuss the difference between oxygen used as a medication to treat hypoxia and oxygen provided as a supportive comfort measure, helping providers better understand when oxygen is clinically indicated.
Participants will also identify patient populations in which excessive oxygen administration may be harmful and review disease-specific considerations that influence oxygen therapy decisions. The session will provide evidence-based strategies for titrating oxygen appropriately, balancing the need to correct hypoxia while avoiding unnecessary exposure to potentially harmful levels of oxygen.
