MESURE DE PRESSION ARTÉRIELLE MOYENNE (MAP) SUR DES PATIENTS POURVUS D'UN DISPOSITIF D'ASSISTANCE VENTRICULAIRE À FAIBLE PULSATILITÉ

摘要

An implantable blood pump system including a blood pump, an impeller in communication with the blood pump, and a controller in communication with the blood pump. The controller is configured to measure a current drawn by the blood pump and a blood flow from the blood pump during operation, correlate the current to a systolic arterial pressure and a diastolic arterial pressure, and adjust a speed of the impeller relative to a predetermined speed and the blood flow to correspond to an increase in the current correlated to the systolic arterial pressure and a decrease in the current correlated to the diastolic arterial pressure.
