Abstract
A blood treatment system with pressure sensors may be configured to control blood flow to and from the patient and use readings of the pressure sensors to determine a change in a pressure drop across a flow restriction in the blood circuit to estimate a condition of the machine or the patient, or outputting data responsive to the estimation. Further embodiments employ measurement of pressure drop to detect abnormal viscosity or viscosity variations in order to detect possible infection.
