In the following example, a Ventricle is pumping on the left side. The
vacuum setting is at the default 100 mmHg (1.9 psi) level.

To Stop Pumping
To stop pumping, press the appropriate ON button twice within 13
seconds. You must press the button twice to stop the pump (see
Figure ****X). This is a safety feature to prevent accidental
operation.

Weaning
When the patient is to be weaned, the Ventricle output may be set at
any desired flow from 2.0 L/min to full flow (in 0.1 L/min.
increments). ****[Selecting desired flow rate]
****[Figure]
During the weaning operation, the Console’s displayed flow may vary
for several beats from the selected flow setting. This may occur when
patient conditions change and/or when the Console periodically
adjusts Ventricle ejection duration to optimize flow. However, actual
Ventricle flow will correspond to the selected flow setting.
Adjusting the Low Flow Alarm Level
The low flow alarm level can be adjusted when pumping is ON. It
can be set to any level (in 0.1 L/min steps) between the current flow
rate and 1.8 L/min during normal operation or 1.5 L/min in the
weaning mode.
