6.2. ZERO FLOW MODE

In order to avoid any kind of back flow once the user set a Blood Flow value = 0, the device automatically maintains
a minimum rotation of the impeller (which may vary depending on the pressure detected at the Centrifugal Pump
outlet line).
For this purpose the device monitors the blood flow, displays the alarms at the defined limits and reacts by
intervening in the pump control.
The device has an extra alarm limit of - 0.2 LPM not settable by the user. In any moment, if the blood flow falls
below that limit for more than 1 sec, a medium priority alarm is generated and a prompt automatic RMP adjustment
occurs to prevent back flow. The alarm ends as soon as the measured blood flow value rises above the alarm limit.
