Abstract
An extracorporeal circulation blood or treatment device () comprising an arterial pressure sensor () and a blood pump () is set up to determine amplitude variation and frequency of the pressure signals received from said arterial pressure sensor (), calculate a parameter value based on said amplitude variation and said frequency, and issue an alarm if the parameter value exceeds a pre-set threshold value. Such detection aims at monitoring the occurrence of oscillating pressure signals. Such signals indicate an increased risk for hemolysis.
