This book was developed for the pulmonary fellows at The Ohio State University to use as part of their outpatient pulmonary rotation. We suggest focusing on one chapter or topic per month. The book includes many interactive features such as galleries of images, interactive flowcharts and videos. At the end of each chapter is a link to several review questions for each subject. This book includes several topics including pulmonary function testing, cough, asthma, chronic obstructive pulmonary disease, pulmonary rehabilitation, perioperative pulmonary evaluation, bronchoalveolar lavage, interstitial lung disease, sarcoidosis, non-tuberculous mycobacterium, lung cancer screening, lung cancer and endobronchial ultrasound.
