Figure 2. Schematic of an in-line hemofilter added to an ECMO circuit.

Figure 2

Blood from the oxygenator is drained via a three-way stopcock and pigtail tubing (A) to the hemofilter. An alternate connection (B) can be made. Hemofilter circuit blood returns to circuit tubing (C) and a three-way stopcock to the venous bladder. Hemofilter ultrafiltrate is drained by an automated pump (D) and collected and measured with an urometer. An IV pump (E) can be used to supply filter replacement fluids. An electronic flow probe (F) measures actual postmembrane flow for calculation of hemofilter ‘runoff’. Reprinted with permission from Hoover et al. [62].
