here's what it said

There's a good way to remember Pulsus Paradoxus

*********
You [gasp] when you are [shocked]
When you [inspire] you get [low blood pressure and tachycardia]
*********

The low blood pressure refers to pulsus paradoxus and the tachycardia refers to sinus tachycardia

 

[khanar]

that's a nice tip

different mechanisms of pulsus paradoxisus

How does the pathophysiology of pulsus paradoxus differ in cardiac tamponade from constrictive pericarditis from asthma.

I understood that of normal systolic pressure decrease in normal inspiration and tamponade but not of asthma and pericarditis

pulsus parad. - can be caused by anything that increased inspiration , or decreases heart filling.

increasesd inspiration -- moa for - asthma
decreased heart filling -- is moa for - tamponade
