Comparison of traditional and plethysmographic methods for measuring pulsus paradoxus.
BACKGROUND In the evaluation of patients with acute asthma, pulsus paradoxus (PP) is an objective and noninvasive indicator of the severity of airway obstruction. However, in children PP may be difficult or impossible to measure. Indwelling arterial catheters facilitate the measurement of PP, but they are invasive and generally reserved for critically ill patients. OBJECTIVE To determine the ...

Systolic blood pressure normally falls during quiet inspiration in normal individuals. Pulsus paradoxus is defined as a fall of systolic blood pressure of >10 mmHg during the inspiratory phase. 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 exacerbatio...

was 80/40 mmHg. The electrocardiogram showed sinus rhythm (90 bpm) with no signs of myocardial ischaemia. Consciousness returned within few seconds, and full consciousness was achieved after 3 min. The BP recovered over time. A computed tomography scan was then performed to investigate the thoracic aorta. Slight pericardial and bilateral pleural effusions were observed with a normal aorta and n...
متن کاملMechanism of pulsus paradoxus in clinical shock.
An inspiratory fall in systolic arterial pressure of more than 10 mm Hg (pulsus paradoxus) was noted in 30 of 61 patients with shock. Inspiratory right atrial pressures and total blood volumes were significantly lower in patients with pulsus paradoxus. Rapid infusion of dextran in 22 patients usually was effective in reversing the exaggerated inspiratory fall in systolic pressure. Total periphe...
متن کاملClinical signs in medicine: pulsus paradoxus.
Historical Aspects The reduction in pulse volume during inspiration was first described by Lomer in 1669 in constrictive pericarditis1. A similar finding was described by Floyer and later by William in 1850 in bronchial asthma1. Adolf Kussmaul (Freiberg, Germany) coined the term pulsus paradoxus in 1873 in three patients with constrictive pericarditis. The paradox was: (1) the discrepancy b...
