Eligibility

Age

18 Years to 99 Years

Inclusion criteria

Inclusion criteria: All patients who are treated with chronic intermittent haemodialysis at the dialysis unit of the VU University medical center.

Exclusion criteria

Exclusion criteria: Younger than 18 years of age; medical, ethical and practical drawbacks or objections to participate. Patients with a pacemaker or implantable cardioverter-defibrillator (ICD) will be excluded.

Design outcomes

Primary

Measure	Time frame
The study parameters are ISTI, delta-ISTI (respiratory variation in ISTI), RR-interval, delta-RR (respiratory variation in RR-interval), ISTI/RR, delta-ISTI/RR (respiratory variation in ISTI) systolic, diastolic and mean bloodpressure, haematocrit value and calf impedance. Also the occurrence of hypotensive periods will be recorded.	—

Secondary

Measure	Time frame
Relative blood volume (RBV), total bodywater, extracellular water and calf extracellular resistance in order to compare parameters derived from ISTI with more traditional markers of haemodynamic status during haemodialyis . These markers will be combined in order to establish the most predictive model for the occurrence of intradialytic hypotension. Also descriptive and anthropometric data will be collected.	—
