The Cleveland Clinic
  Purpose
The investigators propose to test the hypothesis that the incidence of major complications related to infection or inadequate healing is reduced in morbidly obese patients given 80% inspired oxygen during, and for 12-18 hours after, surgery compared with patients given 80% oxygen only during surgery. The primary outcome will be a composite of major complications plausibly related to infection or healing.
