It is an abnormally large decrease in systolic blood pressure and pulse wave amplitude during inspiration.
When the drop is more than 10 mm Hg, it is referred to as pulsus paradoxus. Pulsus paradoxus is not related to 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. The paradox in pulsus paradoxus is that, on clinical examination, one can detect beats on cardiac auscultation during inspiration that cannot be palpated at the radial pulse. Pulsus Paradoxus indicated by optical plethysmograph. Pulsus Paradoxus (PP) is an exaggeration of the normal variation in the pulse during the inspiratory phase of respiration in which the pulse becomes weaker as one inhales and stronger as one exhales. It is more technically described as an inspiratory fall in the systolic blood pressure greater than 10 mm Hg..  Definition of Pulsus Paradoxus: Pulsus paradoxus is defined as a decrease in systolic blood pressure of greater than 10 mm Hg with inspiration. It is detected by inflating a blood pressure cuff above systolic pressure and then slowly deflating it.  pulsus paradoxus, an abnormally large decrease in systolic blood pressure and pulse wave amplitude during inspiration. The normal fall in pressure is less than 10 mm Hg. An excessive decline may be a sign of tamponade, adhesive pericarditis, severe lung disease, advanced heart failure, or other conditions. Also called paradoxic pulse. inequality of the pulse obervable at corresponding sites on either side of the body. pulsus paradoxus. an abnormal inspiratory decrease in arterial blood pressure, seen in cardiac tamponade and caused by a decreased pulmonary venous return. Pulsus paradoxus is associated with many clinical conditions and is defined as a greater than 10 mm Hg end-inspiratory decrease in systolic blood pressure. Kussmaul's original definition of pulsus paradoxus is presented, along with an explanation of his choice of the term pulsus paradoxus..  Definition. The simplest definition of pulsus paradoxus is an exaggeration of the normal inspiratory decrease in systolic blood pressure. The current formal definition of pulsus paradoxus is an inspiratory fall of systolic blood pressure of greater than 10 mm Hg. History Pulsus paradoxus (PP), also paradoxic pulse or paradoxical pulse, is an abnormally large decrease in systolic blood pressure and pulse wave amplitude during inspiration. The normal fall in pressure is less than 10 mm Hg. The paradox in pulsus paradoxus is that, on clinical examination, one can detect beats on cardiac auscultation during inspiration that cannot be palpated at the radial pulse. Published on Sep 26, 2014. Pulsus paradoxus (PP), also paradoxic pulse or paradoxical pulse, is 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.
