This chapter from Outdoor Emergency Care: A Patroller's Guide to Medical Care (6th edition) outlines the foundational principles and practical aspects of the National Ski Patrol's (NSP) Outdoor Emergency Care (OEC) program. It details the resources available for both instructors and students, including textbooks, online materials, and multimedia. The lesson plan emphasizes key objectives for OEC Technicians, such as understanding the program's history, the certification process, and critical legal and ethical considerations like Good Samaritan laws, abandonment, negligence, and patient consent. Ultimately, the document serves as a comprehensive guide for those training to provide prehospital emergency care in diverse outdoor settings, bridging the gap between urban medical services and wilderness rescue.
