This Handbook of Respiratory Medicine has been written largely by specialist registrars, for specialist registrars. Three of the four authors, Stephen Chapman, Grace Robinson, and Sophie West, are specialist registrars on the Oxford rotation and John Stradling is Professor of Respiratory Medicine in Oxford. It is in a format that the authors would like to have had when they started their specialist registrar training. However, we hope that any health worker or student with an interest in respiratory medicine will find this text a rapid and useful reference source. The Oxford Handbook of Respiratory Medicine provides a fast, reliable look-up reference on all chest diseases. The second edition of this comprehensive Handbook has been revised throughout, with additional material on avian flu and respiratory medicine in pregnancy, and updated references to the latest British Thoracic Society guidelines.
