The BVA-100 utilizes patient height, weight, gender, measured tracer counts and measured hematocrits to automatically generate a detailed blood volume report. The report includes three basic volume parameters:
- Total Blood Volume (TBV)
- Red Blood Cell Volume (RBCV)
- Plasma Volume (PV)
Each parameter is expressed in milliliters (mL) and as a percent excess/deficit versus the calculated patient ideal values to determine whether the patient has a normal blood volume (euvolemic), depleted blood volume (hypovolemic), or expanded blood volume (hypervolemic).
Additional Parameters Reported
The report also provides the peripheral hematocrit (pHct), a normalized hematocrit (nHct) and the rate of albumin transudation.
- The peripheral hematocrit (pHct) is the measured hematocrit of the patient samples
- The normalized hematocrit (nHct) is the theoretical Hct any TBV deviation from ideal were corrected by adjusting the plasma volume. This measure is useful for illuminating red blood cell deviations not revealed by standard hematocrit and hemoglobin serum blood tests
- The rate of albumin transudation calculated by the BVA-100is is a unique measure of capillary permeability. It informs clinicians the rate at which albumin I-131 tracer is moving (transudating) from the intravascular space to the extravascular space expressed as a percentage per minute.
