Question

Quizplus · Accepted Answer

A drop in blood pressure of greater than 10 torr during inspiration is called pulsus paradoxus. This is a characteristic finding in conditions where there is increased pressure on the heart or lungs, such as cardiac tamponade or severe asthma exacerbations. Pulsus obliterans, tardus, and alternans are not related to changes in blood pressure during inspiration.
