Bacterial Contamination of Oxygen Used Clinically— Importance and One Method of Control

J D Mortensen M.D., F.C.C.P.1; Gloria Hurd B.S.1; and Gilbert Hill Ph. D.1

1 Rumel Chest Clinic and the Departments of Thoracic Surgery and Bacteriology, Latter-Day Saints Hospital

1. Standard bacteriologic sampling and culturing techniques have demonstrated conclusively that viable bacteria exist in oxygen used clinically.

2. Quantitative tests indicate oxygen used under hospital conditions contains bacteria in approximately the same numbers as does atmospheric air in the hospital.

3. Bacteria cultured from medical oxygen supplies comprise the common airborne contaminants.

4. An efficient, small, inexpensive, reliable sterilizing filter has been developed which can be inserted into the oxygen line and will effectively sterilize oxygen at flow rates up to 15 liters per minute.

5. Indications for use of sterile oxygen in clinical medicine have been presented.
