Question: EB is a 45 y/o male without a significant past medical history. He presents to the walk-in clinic with reports of acute shortness of breath. SPO2 84% and he appears in distress. He works on a construction site and reports a heavy slab of concrete hitting his chest this morning when it slipped off the back of his truck. What will your initial assessment be? What do you expect to hear on auscultation? In addition to lung sounds, what is important to note for a patient in acute distress? What are your differential diagnoses? What diagnostics might you need to determine your treatment plan?
