From: The use of lithium dilution for measuring cardiac output and shunt fraction in patients during venovenous extracorporeal membrane oxygenation: a feasibility study in a flow model

Figure 1

Diagram of the flow model. Pump C representing the cardiac output was set up to draw 3 l/min from the 50 l bucket of saline. Some of this flow passed via the ECMO pump (E) through the membrane oxygenator (M) and then either recirculated through the ECMO circuit via the shunt pump (S) or returned to the bucket. LiCI injections were made just downstream of the oxygenator and dilution curves were recorded simultaneously by the sensors A and B.
