Automated Blood Volume Regulation During Hemodialysis
Intradialytic hypotension (IDH) is the most common complication of hemodialysis (HD), occurring in up to 20 to 33% of sessions (Daugirdas, 2001). IDH is responsible for various minor symptoms (nausea, vomiting, muscle cramps, dizziness, and fatigue) during dialysis, but is also associated with more severe adverse events such as myocardial infarction (Burton et al., 2009) and cerebral ischemia (...
متن کاملDiagnostic utility of blood volume monitoring in hemodialysis patients.
BACKGROUND Assessment of volume state is difficult in hemodialysis patients. Whether continuous blood volume monitoring can improve the assessment of volume state is unclear. STUDY DESIGN Diagnostic test study. SETTINGS & PARTICIPANTS Asymptomatic long-term hemodialysis patients (n = 150) in 4 university-affiliated hemodialysis units. INDEX TESTS Ultrafiltration rate (UFR) divided by post...
متن کاملCritical evaluation of blood volume measurements during hemodialysis.
Devices that continuously measure relative blood volume (RBV) changes during hemodialysis (HD) are increasingly used for the prevention of dialysis hypotension and fine-tuning of dry weight. However, RBV measurements are subject to various limitations. First, RBV devices provide information on relative blood volume changes but not on absolute blood volume. Since blood volume varies with the hyd...
متن کاملRelative blood volume changes underestimate total blood volume changes during hemodialysis.
BACKGROUND Measurements of relative blood volume changes (DeltaRBV) during hemodialysis (HD) are based on hemoconcentration and assume uniform mixing of erythrocytes and plasma throughout the circulation. However, whole-body hematocrit (Ht) is lower than systemic Ht. During HD, a change in the ratio between whole-body to systemic Ht (F cell ratio) is likely to occur as a result of a net shift o...
