Awesome and Invaluable Reference
Format: Paperback
I purchased the 2nd Edition Reprint in 2023. As a former US Army Special Operations Critical Care Flight Medic (160th SOAR Nightstalker) and current Remote Critical Care Flight Paramedic, I can honestly say this handbook is leaps and bounds above some of the other handbooks I've owned. I never leave home and go to work witout it.
