Hi!
We used the Sensormedics with low-volume-strategy alot in case of pie. Then we we lost a lot of our "old" colleagues and a lot of Knowledge concerning the hfov got lost. I think the sensormedics is a very powerful machine which also can do a lot of harm in inexperienced hands.
Therefore we switched to conventionale mechanical ventilation combined with taping of the chest - we use low tidal volumes, very short insp. time (0,1 - 0,2 s).
We try to establish a stable situation with NAVA as soon as possible (without any evidence, but good experinces).
