May explain postoperative hypoxemia after CABG with CPB; leaves open whether targeted interventions improve outcomes.
Does CABG with CPB alter lung structure and blood oxygenation in non-hypoxemic patients with normal cardiac function?
CABG with CPB induces profound structural lung modifications, including reduced gas volume and increased tissue volume, which collectively contribute to postoperative hypoxemia.
Rodrigues et al. (2011) studied this question.
