Monitoring Outpatient Blood VolumE in Heart Failure

"The BVA-100 is a software package designed to calculate human blood volume using the method of tracer dilution. It uses tagged serum albumin (a commonly used tag is 131I, resulting in 131I -HSA). Data inputs to the software come from the measured characteristics of subject blood samples (hematocrit and tracer concentration) and tracer calibration standards. The package also calculates the subject expected (or ideal) blood volume from physical parameters. Hyper- or hypovolemia, associated red blood cell volumes, and transudation rate are reported, with statistics showing the quality of the results. The subject blood samples and calibration standards are measured in a gamma counter, whose output is automatically, or manually, input to this calculation program."
