1. A system for extracorporeal blood treatment comprising:

  • (a) an extracorporeal blood path comprising an arterial line in fluid communication with a first vascular access and an inlet to a blood treatment device, and a venous line in fluid communication with an outlet of the blood treatment device and with a second vascular access;

    (b) an arterial fluid pressure sensor in communication with the arterial line and constructed and arranged for measuring pressure within the arterial line;

    (c) a venous fluid pressure sensor in communication with the venous line and constructed and arranged for measuring pressure within the venous line;

    (d) a computer unit connected to the arterial and venous pressure sensors, which is constructed and arranged for generating first and second characteristic values for the integrity of the vascular access from measured arterial and venous pressures;

    (e) an analyzer unit constructed and arranged for analyzing the integrity of the vascular access by comparing the first and second characteristic values to first and second ranges of predetermined values.
