STOP WEANING
Weaning can be suspended or terminated in several ways.
1. 100% VOL. @ 1:1 Key: This key will immediately stop weaning and resume full
support at 100% Volume and 1:1 assist.
2. Changing assist ratio: If the assist ratio is changed while weaning is in use, the
weaning program will be suspended. All previous weaning settings will be retained for
future use.
3. Changing IAB volume: If the IAB volume is changed while weaning is in use the
weaning program will be suspended. All previous weaning settings will be retained for
future use.

When the timer expires for a weaning step, a Class 3 alert will be displayed:

WEANING OR RESUME FULL IABP SUPPORT
Current IAB volume and assist ratio from the weaning setup will be used for pumping
until another weaning setup is selected or until pumping is discontinued.
WEANING AND INTERNAL TRIGGER MODE
Weaning cannot be set when INTERNAL trigger mode is selected. The user must change
to another trigger mode if the weaning mode is required. If you are in weaning and the
INTERNAL trigger mode is selected and confirmed by pressing the INTERNAL key
twice, weaning will be suspended and the INTERNAL mode will be selected.
NOTE: IAB volume cannot be reduced more than 50% of the IAB connector volume in
the weaning setup. Generally, IAB volume should not be reduced more than 30% of the
full volume.
