After confirmation of eligibility criteria, the following steps should be
performed under echo guidance
1 :
1. Administer unfractionated heparin (UFH) 75 units/kg x _____ kg =
_____ mg IV x 1 [max 5000 units].
2. After 5 minutes, reduce the pump rate step-wise from IR (_____ bpm)
to 30 bpm in increments of 5 bpm q5 min. After 5 minutes at 30 bpm,
reassess LV size and function.
3. After an additional 5 minutes (i.e. total time = 10 min at 30 bpm), stop
the pump for 3 min and reassess LV size and function. During pump
stoppage, use the manual pump to pump twice q30 seconds to
minimize the risk of thrombus formation due to blood stagnation while
Ikus is disconnected.
4. After 3-minute pump stop, reconnect pump to Ikus and resume pump
speed at IR(___ bpm).
Did the patient satisfy all 5 eligibility criteria
throughout the period of weaning and pump
stoppage?
