Austere environments demand a nuanced approach to the critically ill, especially when care is prolonged and resources are scarce. This session introduces a simplified, high-yield POCUS framework designed specifically for these realities. Moving beyond unnecessary gadgetry, we focus on the most practical exams (Heart, Lung, IVC, Ocular) that drive immediate clinical decisions regarding austere resuscitation and transport. Attendees will leave with an evidence-based strategy to integrate ultrasound into their existing workflows, enhancing their physical assessment when timelines are unpredictable and isolation is the defining factor.
