The device the oxygen tank is sitting on looks like a oxygen generator. It spins room air in a centrifuge and creates near 100% oxygen. It would be used by someone on oxygen, the E tank of oxygen connected to it is for backup when the electricity goes out. Its strange that it is sitting outside though.
