How Does the BVA Provide Accurate Blood Volume Measurement?
The BVA-100 is a semi-automated blood volume analyzer. The instrument is used in conjunction with a single-use injection kit consisting of a precisely measured standard and matching injectate. The injectate is packaged in a patented flow chamber designed to ensure 99.8%+ delivery. The kit improves accuracy and eliminates the many time-consuming and difficult steps required for on-site standard preparation. The BVA-100 utilizes five separate sampling points taken at regular intervals starting approximately 12 minutes after injection. In effect, each sample measurement is a separate, single-point blood volume determination. The BVA-100 computes the transudation time for the tracer and calculates the true zero point blood volume with an accuracy of approximately ± 2.5%. The BVA-100 provides interim blood volume results while the samples are being measured; preliminary data is available within 30 minutes and may be used to guide decisions in emergency situations.
