Aortic Regurgitation : Collapsing Pulse

The most common confusion for this sign is : 


collapsing pulse positive = no pulse felt when raising the hand up. correct, no?


Answer : false! collapsing pulse is positive if we feel a "knocking" sensation on our palm. that means, in normal healthy patient, there will be no knocking sensation.


Method : 


1. locate for radial pulse
2. place our palm over it
3. ensure that patient has no problem to lift the arm. who knows the patient has fracture. 
4. while still placing palm on it, quickly raise the patient's hand above his head. 
5. look for the sensation!
