Pulsus paradoxus, also paradoxic pulse or paradoxical pulse, is an abnormally large decrease in stroke volume, systolic blood pressure (a drop more than 10 mmHg) and pulse wave amplitude during inspiration.Pulsus paradoxus is not related to pulse rate or heart rate, and it is not a paradoxical rise in systolic pressure. Normally, blood pressure drops less precipitously than 10 mmHg during 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 Keep slowly deflating the cuff until you reach the highest BP when you hear sounds with every beat (no longer intermittent) This corresponds to the systemic blood pressure during inspiration. The difference between two pressures is the "pulsus paradoxus". >10 mmH is considered significant. Severe pulsus paradoxus can be palpated in the pulse as Pulsus paradoxus has interested physicians for more than a century. Since McGregor's comprehensive New England Journal of Medicine article in 1979, 1 there have been no updated reviews; accordingly, we review pulsus paradoxus based on the clinical and physiologic literature and personal experience. 2.
