About the Authors
  • A sound knowledge of equations and their use, derivation and clinical application is an absolute prerequisite for any anaesthetist. As a result, equations are a favourite question topic of examiners, particularly in the viva examinations. Many candidates answer these poorly, losing valuable marks and floundering when they face what they perceive as “nightmare” questions. This book provides a simple, portable, reference guide to all the equations that candidates may be asked about during their examinations. The content is split into four sections; physics, pharmacology, physiology and statistics. Each equation is clearly explained, derived where necessary, and placed into a clinical context using a worked or clinically relevant example to demonstrate its use. Units and relevant terms are given and where required, clear, concise diagrams have also been provided to simplify understanding. Written by anaesthetic trainees, this is an essential resource for preparation for the FRCA, EDA and other anaesthetic examinations.

    • Includes all of the equations relevant for the FRCA and EDA, ensuring candidates have all of the information they need in one place
    • Concise explanations aid quick revision
    • All of the equations are applied to clinical practice, giving the content wide-reaching relevance
