Figure 4From: Central extracorporeal life support with left ventricular decompression for the treatment of refractory cardiogenic shock and lung failure Setup of the presented circuit on intensive care unit. RA indicates right atrium, LV left ventricle and Ao ascending aorta. The arrows indicate the direction of blood flow. The three-way taps are used for blood sampling to measure pre-pulmonary mixed venous oxygen saturation and post-pulmonary arterial oxygen saturation. Thus, the effectiveness of the circuit can be monitored continuously and accurately.Back to article page
