transfer compared to oxygen through the membrane lung, creating a potential for
hypocarbia. A gas flow rate equal to blood flow rate (1:1) is typically used to
begin support, with tailoring further adjustments of the rate to the carbon dioxide
level: increasing sweep gas decreases the level and vice versa. See Table 2 for
specifications of different gas exchangers.
