Optimized Blood Volume Monitoring during Hemodialysis Procedure based on Ultrasonic Speed Measurement
Fast reduction of blood water volume due to ultra-filtration via hemodialysis machine and critical threshold of blood water volume can result in clinical complications such as hypotension. When blood water volume reduces during hemodialysis process, the concentration of blood forming elements will increase. One of the methods for the monitoring of the concentration changes is ultrasonic speed m...
متن کاملAutomated 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 کاملThe Determination of the Circulating Blood Volume with Carbon Monoxide.
The estimation of the circulating blood volume in man is of interest in the study of a number of clinical problems. The results published by many investigators have varied widely. The principle involved in all of these studies consists in the introduction into the blood stream of a measured amount of some substance whose concentration in the circulating blood may then be estimated after complet...
متن کاملBedside monitoring of circulating blood volume after subarachnoid hemorrhage.
BACKGROUND AND PURPOSE Maintenance of an adequate intravascular volume is important in the management of patients with subarachnoid hemorrhage (SAH). The purpose of this study was to investigate the circulating blood volume (CBV) after SAH with the use of indocyanine green pulse spectrophotometry. METHODS CBV and plasma hormones related to stress and fluid regulation were measured 4 times: da...
