Continuous blood volume monitoring (CBVM) is believed to be a promising method for making the determination of patients' "dry weight" more objective, and ultrafiltration (UF) control more appropriate. Although blood volume response to UF and the interrelation between blood volume changes and changes in hemodynamic parameters are highly individual, certain principles of this response and interre...

objectives the main objective of this study was to design and construct an optical device to determine the rbv in patients undergoing hemodialysis, during the process. materials and methods after initial studies in order to select a proper sensor, using the orcad software, an analog circuit was designed. the implementation and modification of the circuit was done by the clinical tests, using ex...

BACKGROUND The hemodynamic balloon model describes the change in coupling from underlying neural activity to observed blood oxygen level dependent (BOLD) response. It plays an increasing important role in brain research using magnetic resonance imaging (MRI) techniques. However, changes in the BOLD signal are sensitive to the resting blood volume fraction (i.e., [Formula: see text]) associated ...

The importance of extracellular volume control and avoidance overload has been well documented in relation to the management patients with chronic haemodialysis. Chronic results poorly controlled hypertension, increased cardiovascular events, all-cause mortality. Traditional methods dry weight assessment have relied on clinical guide status. challenge achieving balance between weights preventin...

background: one of the main problems especially in operating room and monitoring devices is measurement of blood pressure (bp) by sphygmomanometer cuff. objective: in this study we designed a new method to measure bp changes continuously for detecting information between cuff inflation times by using vital signals in monitoring devices. this will be achieved by extraction of the time difference...
