Abstract
A method of predicting an adverse event in a patient having an implantable blood pump including correlating a pulsatility value to a flow trough value associated with the blood pump to determine a flow peak value; dividing the determined flow peak value by a pump current to determine a pulsatility peak value; tracking a first moving average of the pulsatility peak value, the first moving average defining a threshold range; tracking a second moving average of the pulsatility peak value, the second moving average being faster than the first moving average; and generating an alert when the second moving average deviates from the threshold range.
