Improve your skills in visual diagnosis

Speed and accuracy of diagnosis is the key to saving lives in emergency and critical care medicine. Careful visual inspection of the patient, the data (radiography, electrocardiogram), and related clues can often help providers choose the right diagnosis and ultimately the best treatment – but this knowledge comes with experience. This book provides 110 randomly presented visual diagnosis cases for self-testing, imitating real-life situations found in the emergency department setting.

Written by distinguished emergency and critical care physicians, and thoroughly revised and updated throughout, this second edition includes 25% new cases and is an ideal aid for trainees preparing for Board examinations as well as an invaluable 'refresher' for qualified emergency and critical care providers.
