Medical Handbook for Walkers and Climbers by Peter Steele
This book will help you take the step from the standard first-aid course to simple expedition medicine. As the author says, read it at least once at home before throwing it in the bottom of your pack, where hopefully it will lie undisturbed. Learn how to distinguish appendicitis from a ruptured spleen, hyper- from hypo- glycaemia, or three different ways to re-set a dislocated shoulder. It also suggests a list of drugs for your wilderness expedition medical pack, with their uses and side-effects. This makes the book valuable for self-diagnosis and for informed participation in any decisions about treatment you may yourself need.
