Eligibility Criteria:
Inclusion Criteria:~1. Age 18-80+/- referred and considered a candidate for a synthetic hemodialysis access graft.~2. Baseline room air arterial blood concentration \>70 and arterial carbon dioxide concentration 45 mmHg. Pulmonary function tests \> 75% predicted values~3. Currently undergoing dialysis~4. No previous synthetic hemodialysis grafts placed in the same arm (fistula in ipsilateral arm permitted)~5. Ability to use 5L/minute supplemental oxygen by nasal cannula~6. Nonsmoker, able to avoid other situations which would constitute a risk for use of oxygen~7. Medical condition with \> 1 year life expectancy~8. Currently on no medications which would interfere with wound healing (i.e. steroids, chemotherapeutic agents)~9. Not pregnant nor planning to become pregnant during study period~Exclusion Criteria:~1. Failure to meet inclusion criteria~2. Failure to comply with study protocol for 3 consecutive days during the 6 wk oxygen/non-oxygen supplement period immediately following graft placement~3. Medical condition developing during study period causing a significantly worsening pulmonary function requiring supplemental oxygen for \> 3 days~4. Need to take medication during study period which would interfere with wound healing any time during the 6 week period immediately following graft placement or need to take chronic medications (\> 6 weeks) during the remainder of the study period.~5. Patient desire to withdraw~6. Failure of evidence of adequate increase in arterial blood oxygen concentration (pa02 \> 115 for oxygen supplemented and pa02 \> 55 mmHg for control obtained from arterial access port during dialysis run~7. Failure to use supplemental oxygen (if in supplemental oxygen group) at least 18 hours per day (as recorded in journal) -
