After trialing the Vasonova, I was not impressed . We did not achieve the bulls eye but cxr showed tip location in the lower third of the svc or in caj. My question is this: When the PICC catheter is too short to reach the caj with these location devices, what next ? Are they saying the catheter needs to be replaced? I get tired of hearing about perfection. We work in the real world and every single line is not going to be exact.
