Presentation transcript:

A: ECMO circuit tubing with component pieces in place, configured with a centrifugal pump. A: ECMO circuit tubing with component pieces in place, configured with a centrifugal pump. Patient outflow tubing marked with blue tape (venous limb) draws deoxygenated blood from patient into the pump. Patient inflow tubing marked with red (arterial limb) tape returns oxygenate blood to the patient. This circuit is configured with a centrifugal pump interface. B: ECMO cart with all component pieces in place, configured with a rotary pump. C: Maquet Cardiohelp system. 1: Artificial lung (Maquet Quadrox) provides extracorporeal gas exchange. 2: External pump provides driving force for blood flow through the ECMO circuit. This can be either a centrifugal or rotary pump. The blood flow circuit tubing in A is configured for a centrifugal pump interface, whereas B depicts a rotary pump. 3: Blood parameter monitoring system (Temuro CDI) uses fluorescence sensors on the venous and arterial sides to monitor continuously pH, PCO2, PO2, oxygen saturation, hemoglobin/hematocrit, HCO3, and potassium. 4: Gas source delivers fresh medical gas (oxygen and air) modified by a flow meter and blender, shown in B, to the artificial lung via green tubing, shown in A. 5: Blood flow meter continuously monitors blood flow through the ECMO circuit via a sensor on the arterial limb tubing, serving as a direct measure of blood flow. 6: Bioconsole monitors blood flow generated by the external pump and the generated circuit pressures on the venous and arterial limbs. A display screen on the lower console displays flow characteristics generated by the external pump. 7: External heater uses a water bath to rewarm the blood while outside the patient to prevent hypothermia. 8: Maquet Cardiohelp system combines the artificial lung, a centrifugal pump, and bioconsole monitoring system into one unit, allowing smaller circuit priming volumes and a more streamlined overall circuit configuration.
