Claim:
1. A method for controlling an implantable blood pump with an external controller, the method comprising: identifying a status of one or more power sources for the implantable blood pump that is indicative of a mode to conserve power; and transmitting, from the external controller, a command signal to the implantable blood pump to transition the implantable blood pump from a pulsatile pumping operation to a constant speed operation, the constant speed operation consuming less power than the pulsatile pumping operation; and receiving and processing, with electronics of the implantable blood pump, the command signal to transition the implantable blood pump from the pulsatile pumping operation to the constant speed operation; wherein identifying the power source status that is indicative of the mode to conserve power comprises: identifying a low power hazard condition status; identifying a duration of time in which the implantable blood pump is operated in the low power hazard condition; and comparing the duration of time to a threshold time period; and transmitting the command signal to the implantable blood pump when the duration of time exceeds the threshold time period.
