We had a pt today I had no clue how to get a B/P on. They had their left arm amputated and their right arm had a dialysis shunt in it. It was a transfer pt, so in the hospital we wrapped the electronic vital machine around their calf and got a BP that way. But in the box (we have no lifepacks) how would you get one? I just wrote "Unable to obtain B/P" on my run form and describe the procedure, but is their a place to listen to that will yield accurate results? I was never trained of one.
