Monitoring system and method for cardiac surgery using cardiopulmonary bypass

摘要

Monitoring system (10) for cardiac surgical operations which includes a processor connected to a heart-lung machine (3), pump flow reading means (42) connected to a pump (4) of the heart-lung machine (3) for measuring the value of the pump flow (Qp) and sending it to the processor, blood hematocrit (HCT) value reading means (43) connected to the heart-lung machine circuit (3) for measuring the HCT value and sending it to the processor, CO2 reading means (eCO2) at the oxygenator gas escape, data input means (50) to manually input data relative to the arterial oxygen saturation (Sat(a)), arterial oxygen tension (PaO2), gas flow (Ve) and computing means (15) to compute the oxygen delivery value (DO2i) and the CO2 production value (VCO2i) on the basis of the detected and inserted values, and a display (11) connected to the processor, to show the calculated values of (DO2i) and (VCO2i).
