  • CONCLUSIONS: Legendary physician Sir William Osler truly said that "Medicine is learned by the bedside and not in the classroom." Bedside history taking and physical examination should be an integral component of clinical teaching curriculum imparted to medical students. Pulsus paradoxus is a valuable physical sign seen in many clinical conditions. Pulsus paradoxus is defined by an inspiratory fall in systolic blood pressure of greater than 10 mm Hg. Two prototype examples of pulsus paradoxus are cardiac tamponade and acute asthma. Exaggerated swings of intrapleural pressure, bi-ventricular interactions and increase afterload of the left ventricle are few of the pathophysiological mechanisms involved in the causation of pulsus paradoxus. The sensitivity of pulsus paradoxus in the diagnosis of cardiac tamponade is very high. In acute asthma, it also correlates with the severity of airflow obstruction.
