Air embolism is rare, but when it happens, you have minutes—not hours—to get it right. This course gives nurse anesthesiologists a focused, practical review of how and where air enters the circulation, how to recognize both massive and subtle events (ETCO₂ changes, hemodynamics, neurology), and how to respond decisively with positioning, resuscitation, and targeted pharmacologic management. You’ll also learn when nitrous oxide becomes dangerous, how risk shifts across neurosurgery, C-sections, cardiovascular and orthopedic cases, and how to use monitoring tools and advanced therapies like HBOT and ECMO to improve patient outcomes in the highest-risk settings.
