Volume expansion is one of the most important factors that results in higher levels of blood pressure in patients with chronic kidney disease. This has been known for many years, and led to the original description of the concept of dry weight in 1967.1 This is especially important in patients with end-stage renal disease who require dialysis for volume control. Inadequate control of volume or ...

Volume management related complications are common during hemodialysis (HD). There is a narrow window between avoiding and obtaining euvolemic individual, who at their dry weight.Relative Blood (RBV) monitoring via Crit-Line utilizes photo optical technology to non-invasively measure absolute hematocrit help determine the optimal weight in real time. Use of can be repeated with every dialysis t...

Using a hematocrit monitoring system and a Swan-Ganz catheter, the authors investigated the changes in blood volume and hemodynamic parameters before, during, and after dialysis-induced hypotension. When hypotension occurred, the cardiac output dropped sharply, and there were concomitant sudden decreases in the mean pulmonary arterial pressure and the mean right atrial pressure. These are attri...

INTRODUCTION Monitoring of circulating blood volume is important in the management of critically ill patients. Current methods of circulating blood volume measurements such as indicator dilution using radioisotopes or Evans blue dye are unsuitable for clinical application as these tests do not allow for frequent repeated measurements to be done. A direct bedside measurement of circulating blood...

BACKGROUND Volume management during renal replacement therapy (RRT) in septic shock is always in the conflict between aggravating hypovolemia by undue ultrafiltration (UF) and insufficient reduction of fluid overload which is associated with adverse outcome. Relative blood volume (RBV) monitoring could be helpful for timely transition from fluid resuscitation to fluid removal. METHODS Data of...

Current methods for measuring renal blood flow (RBF) are time consuming and not widely available. Contrast-enhanced ultrasound (CEU) is a safe and noninvasive imaging technique suitable for assessment of tissue blood flow, which has been used clinically to assess myocardial blood flow. We tested the utility of CEU in monitoring changes in RBF in healthy volunteers. We utilized CEU to monitor th...
