a pulsus paradoxus (PP), also paradoxic pulse or paradoxical pulse, is defined as an abnormally large decrease in systolic blood pressure and pulse wave amplitude during inspiration. The normal fall in pressure is less than 10 mmHg or 10 torr. When the drop is more than 10mm Hg, it is referred to as pulsus paradoxus. Pulsus paradoxus has nothing to do with pulse rate or heart rate. The normal variation of blood pressure during breathing/respiration is a decline in blood pressure during inhalation and an increase during exhalation. Pulsus paradoxus is a sign that is indicative of several conditions, including cardiac tamponade, pericarditis, chronic sleep apnea, croup, and obstructive lung disease (e.g. asthma, COPD).
