Airline pilots, like many other professionals, rely on guides and checklists for routine and emergency procedures. Everyday EMS Tips columnist Greg Friese discusses three resource types he consults for day-to-day and out of the ordinary medical and trauma patients. Greg regularly references his organizations field protocols, two ALS quick reference guides, and paramedic content on his smart phone.
