Such tests can be highly misleading in many surgical and medical situations. One of the most difficult decisions a physician faces is knowing whether to administer a transfusion to a patient who has suffered severe blood loss. In situations of sudden blood loss, such as trauma, hemorrhage or surgery, the BVA-100 provides physicians with two important pieces of information. For the first time, physicians have access to technology which enables them to obtain blood volume measurements rapidly and with a high degree of precision. It is very common for patients to be operated upon in a very severely anemic condition.
Physicians are reluctant to use donor transfusions.
Such brain damage may persist permanently. It is possible, utilizing the Blood Volume Analyzer to measure the blood that a patient has prior to surgery and take some corrective action where needed. Patients who have cardiac disease with narrowed arteries frequently have similar narrowed arteries in the brain. Such patients are at significant risk when surgery is conducted on these patients in an anemic condition. Combining blood substitutes which can deliver oxygen and using frozen blood storage by patients at risk, it is possible to prepare patients so as to avoid operating on patients in a severely blood depleted state.
