- Abstract
It is the goal of this section to publish material that provides information regarding specific issues, aspects of artificial organ application, approach, philosophy, suggestions, and/or thoughts for the future Abstract: In this series, we investigated the meaning of the t-point of index of motor current amplitude (ICA) curve from a point of view of flow rate on in vitro and in vivo studies. On mock circulation loop and left ventricular assist device (LVAD)–equipped pigs, we detected the t-point and compared the pump flow at the t-point with the simultaneous cardiac output. The pump flow at the t-point showed high correlation against the simultaneous cardiac output for in vitro or in vivo study. By detection of the t-point of the ICA curve and measuring or estimating the pump flow at t-point, the cardiac output may be assessed without any sensor in various cardiac conditions.
