Intradialytic non-invasive hemodynamic monitoring: usefulness of cardiac preload values in predicting hemodynamic instability.

Introduction: Adequate control of patient blood volume in hemodialysis (HD) is essential as a modifiable risk factor for morbidity and mortality. In this study, we propose continuous non-invasive hemodynamic monitoring using bioreactance (Starling SV.Baxter) and real-time characterization of cardiac preload data to aid in the accurate assessment of volume status and improvement of tolerance in HD.
