Direct Blood Volume Analyzer for Improvement of Combat Casualty Care

Daxor proposes an automated, ruggedized, portable system for calculating blood, red cell, and plasma volumes, based on a comprehensive adaptation and reengineering of the current gold standard for volume measurement, the Daxor BVA-100. Significant improvements in portability (size, weight, and battery operation), logistics, speed, and ease of use are achieved. Whole blood is sampled directly from the patient, eliminating the need for centrifugation and precision pipetting. Hematocrit measurement is integrated, allowing quantification of all blood compartments. The detection system (detector and shielding) is optimized for portability, and to allow the use of a longer-life tracer. Active technician time is substantially reduced with automated blood draws, with results available in fewer than 20 minutes. Individualized patient norms are displayed along with measured values; recommended corrections to volume derangements are displayed. Achievement of required 95% accuracy is demonstrated by parallel computation using the gold-standard BVA-100, in both laboratory and hospital conditions.
