Abstract
An implantable blood pump includes a control unit storing patient specific settings. The control unit is configured to store patient specific settings. The patient specific settings can be used to determine a target operating speed for the blood pump and/or a target operating mode for the blood pump. The patient specific settings can include at least one of an operating mode for the pump, a set speed for the pump, a lower speed limit for the pump, a patient hematocrit value, a patient hematocrit date, a patient blood density, and a periodic log rate for event and periodic data.
