Off-pump CABG preserves diffusion capacity versus on-pump; extends RCT evidence favoring technique selection by pulmonary risk.
Does off-CPB CABG improve postoperative pulmonary function compared to on-CPB CABG in patients undergoing coronary artery surgery?
Off-pump CABG preserves postoperative pulmonary diffusion capacity compared to on-pump CABG, although both techniques result in similar reductions in spirometry and arterial oxygenation.
