I figure its time to start direct conversation regarding these two systems since our team is looking at both. Each company is trying to rebutt the others statements (which makes it difficult to choose).
What we have been told:
Vasonova - can be used with any non-valved PICC. Relies on doppler flow when a p-wave is not present.
Sapiens - can only be used with a BARD PICC. Relies on Sherlock magnet technology when a p-wave is not present.
Please disclose your affiliation with either of these companies when making a comment.
