\.4. Impr0ved 0xygen delivery 0f a patient receiving ECLS can 0ccur with a. Y0ung
circuitb. Impr0vement in native lung functi0n.c. Increased pump fl0w with
ven0ven0us ECLS.
d. Increasing pump fl0w ab0ve the rated fl0w 0f the 0xygenat0r
Ch2
b, c (There is usually a limit t0 h0w much
increasing pump fl0w impr0ves 0xygen de- livery because at s0me p0int the increase in
recirculati0n that 0ccurs with increases in fl0w 0utweighs the impr0vement in f0rward fl0w.)
\.5. Carb0n di0xide clearance by the ECLS pump in influenced by a. Pre-0xygenat0r
bicarb0nate c0ncentrati0nb. Sweep gas fl0wc. Membrane surface area
d. Sweep gas 02 c0ncentrati0n e. Sweep gas C02
