Throughout the remainder of the text, the authors provide a concise and timely review of common and uncommon clinical scenarios throughout the spectrum of pulmonary medicine. Part II explores “Common Presentations in the Outpatient Setting.” Part III describes “Common Problems in the NonICU Patient,” while part IV evaluates the “Common Problems in the ICU Adult.” Though most chapters vary slightly in presentation style, they all contain similar elements and format so as to enhance the EBM model. At the beginning of each chapter, a different clinical problem is presented, pertinent to the subject at hand. Following the vignette, the authors provide a pathophysiologic explanation; assessment data appropriate to making a differential diagnosis; clinical features that suggest a specific diagnosis; invasive and noninvasive diagnostic testing opportunities; tables that include helpful information for interpreting signs and symptoms; and clinical pitfalls and common mistakes in the assessment and treatment of the diagnosis. In addition, most chapters include appropriate supportive information such as tables, graphics (eg, spirometric tracings, sleep study data, ventilator waveforms), or flow charts and radiologic information that all assist in understanding the formulation of a diagnosis and implementation of treatment, all conforming to EBM methodology.
