Pulsus Paradoxus Asthma. Pulsus paradoxus fluctuation of 10 mm Hg or greater was present on 110 occasions. 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. Pulsus paradoxus can be observed in cardiac tamponade and in conditions where intrathoracic pressure swings are exaggerated or the right ventricle is distended such as severe acute asthma or exacerbations of chronic obstructive pulmonary disease. Its a very specific sign that can only be adequately recognized when monitoring pressure with an arterial catheter.

Pulsus Paradoxis is a fall of systolic blood pressure of 10 mmHg during the inspiratory phase. Pulsus paradoxus is defined as a decrease in systolic blood pressure of more than 10mm Hg during inspiration. 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. Ninety-three patients with asthma were examined on 308 occasions for systolic fluctuation of blood-pressure during quiet breathing. Pulsus paradoxus is a drop in blood pressure of more than 10 mmHg millimeters of mercury when taking a breath. When this occurs the path of least resistance for the right ventricle is not outwards against the fluid but rather into the left ventricle.

Indwelling arterial catheters facilitate the measurement of PP but they are invasive and generally reserved for critically ill patients. Pulsus paradoxus fluctuation of 10 mm Hg or greater was present on 110 occasions. Background In the evaluation of patients with acute asthma pulsus paradoxus PP is an objective and noninvasive indicator of the severity of airway obstruction. Its a very specific sign that can only be adequately recognized when monitoring pressure with an arterial catheter.

In the article Status Asthmaticus 23112771975 the authors state that An increase in the usual pulsus paradoxus is almost always present a sign associated with an increase in the volume of functional residual capacity combined with severe airway obstruction and quote as authority Rebuck and Pengelly 1 who propose that the mechanism responsible for pulsus paradoxus in asthma is in part that of cardiac compression caused by pulmonary overinflation and mediastinal stretching. Pulsus paradoxus results from alterations in the mechanical forces imposed on the chambers of the heart and pulmonary vasculature and is often due to pericardial disease particularly cardiac tamponade and to a lesser degree constrictive pericarditis. Pulsus paradoxus is a common finding in two conditions.
