Hospital Manufactures Oxygen Plant at Medical College of Virginia
The Medical College of Virginia in Richmond completed the largest hospital oxygen plant, second only to Memorial Hospital in Hartford. The unit pipes oxygen to operating and other rooms, producing up to 500 000 cubic feet monthly, with current usage around 150 000 to 200 000 cubic feet. Savings arise from eliminating cylinder deliveries.
