Approach to the Respiratory Patient

Several challenges arise when evaluating a dog or cat with respiratory disease. The history can span a long period, and some owners may have a difficult time in recognizing or describing respiratory abnormalities. A good history and thorough physical examination are essential when evaluating the respiratory patient. There are some noninvasive diagnostics that can aid in the diagnosis of respiratory disease; however, other more invasive tests often require anesthesia, which can be a potential hazard with a respiratory patient. This article focuses on reviewing the function of the respiratory system and how best to identify and diagnose cats and dogs with respiratory disease by implementing a thorough history and physical examination as well as appropriate diagnostic testing.
