This session on aerospace and extreme environment nursing with Dr. Glenn Barnes will explore the unique challenges of delivering medical care in some of the most hostile and unconventional settings on earth. With over 30 years of experience spanning military special operations, combat deployments, emergency preparedness, and academic leadership, Dr. Barnes brings a rare and deeply informed perspective on nursing practice beyond traditional clinical environments. Participants will gain insight into the physiologic and operational demands of aerospace and extreme environments, including austere, high-risk, and resource-limited settings. The lecture will highlight critical concepts such as adaptability, risk mitigation, and interdisciplinary coordination, drawing on real-world experiences from military operations, disaster response, and global security missions. Ideal for healthcare providers interested in wilderness, tactical, and expedition medicine, this talk will expand learners’ understanding of how nursing skills translate to extreme environments—and how to prepare for delivering high-quality care when conditions are anything but ordinary.
