Patent ID: 11826559

Abstract:
The invention comprises an apparatus and a method for operating a cardiac assist pump, comprising the steps of: (1) providing a cardiac monitor comprising: a cardiac output sensor including an activity sensor and at least two of: a pulse oximeter; an electrocardiogram meter; and a blood pressure monitor; (2) receiving time-varying cardiovascular input data, from the cardiac output sensor, related to a transient hemodynamic state of a cardiovascular system; (3) receiving and operating on time-varying activity input data, from the activity sensor, to generate cardiovascular state information; (4) sensing activity with the activity sensor to generate a target cardiovascular state; (5) repeating both the steps of receiving and operating to update the transient cardiovascular state information and the step of sensing to update the target cardiovascular state; and (6) directing the cardiac assist pump to adjust assisted blood flow, yielding the updated transient cardiovascular state, toward the target cardiovascular state.
