Abstract
Example embodiments of the present invention provide methods and apparatuses that enable the detection of bubbles so that hemodynamic performance can be assured following an automated blood analyte measurement. An example apparatus according to the present invention comprises a blood access system, adapted to remove blood from a body and infuse at least a portion of the blood back into the body. The infusion of at least a portion of the blood back in to the body can be done in a manner to assure that no bubbles of clinical significance are injected into the patient. Additionally an example embodiment can assess for the presence of bubbles in the fluid column that can affect hemodynamic monitoring performance. If a condition exists where hemodynamic monitoring performance cannot be assured, an example embodiment can provide appropriate warning or corrective actions.
