"How to use this guide The International Medical Guide for Ships is easy to read and understand. It tells you how to diagnose, treat and prevent health problems in seafarers, with a focus on the first 48 hours after injury. It should be kept in the ship's medicine chest, and you should familiarize yourself with the content before a medical emergency occurs. This way, when there is a case of illness or injury on board, you can immediately turn to emergency medical advice on the topic at hand. Chapters 1–24 follow this structure:
■ general description of symptom or disease
■ explanatory notes when necessary
■ signs and symptoms
■ key questions to ask
■ what to do
■ what not to do! "
