Also intraoperative blood salvage (IBS) requires a system for quality management with controls of product an process quality. These can help early detection of malfunctions. For proper reaction and for improvement of quality a deep understanding of the process of blood salvage is necessary. This is supported by experimental testing of equipment, programs, and process variables, and by analysis of their effects on the process. The use of fresh whole blood and total protein as wash-out parameter in these tests is superior to outdated banked RBC and free haemoglobin. The process of aspiration turns out much less harmful than expected, when tested with fresh blood. Low wash volumes, fast washing rates, and half full bowls should be avoided. Plasma wash-out is improved by slower washing or by higher wash volumes, but the latter decrease RBC recovery. Such quality management helps to provide blood of excellent quality by IBS for optimal haemotherapy.
