Title
(EN) METHOD OF MONITORING HEALTH CONDITIONS OF A PATIENT HAVING AN IMPLANTABLE BLOOD PUMP
(FR) PROCÉDÉ DE SURVEILLANCE D'ÉTATS DE SANTÉ D'UN PATIENT PORTANT UNE POMPE SANGUINE IMPLANTABLE
Abstract
(EN)
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.
(FR)
L'invention concerne un procédé de prédiction d'un événement indésirable chez un patient portant une pompe sanguine implantable consistant à mettre en corrélation une valeur de pulsatilité avec une valeur de circulation associée à la pompe sanguine de façon à déterminer une valeur de pic de circulation ; à diviser la valeur de pic de circulation déterminée par un courant de pompe pour déterminer une valeur de pic de pulsatilité ; à suivre une première moyenne de fluctuation de la valeur de pic de pulsatilité, la première moyenne de fluctuation définissant une plage seuil ; à suivre une seconde moyenne de fluctuation de la valeur de pic de pulsatilité, la seconde moyenne de fluctuation étant plus rapide que la première moyenne de fluctuation ; et à générer une alerte lorsque la seconde moyenne de fluctuation s'écarte de la plage seuil.
