Welcome to JA and thanks for this question. Im sorry to hear about your friend. Actually your friend needs to be taken to the ER IMMEDIATELY, the swelling of the feet along with the toes and feet turning black are a clear indicator of ischemia or lack of blood supply to the feet. This is UNLIKELY to be related to the use of oxygen as oxygen would NOT cause the blood supply to drop off in the feet. The black discoloration is more in line with a blood clot in the arteries or even due to peripheral arterial disease (SEVERE) in which the arteries are narrowed to such an extent that the blood supply to the distal tissues is compromised. This would also cause pain, swelling, numbness, cold feet. The diagnosis in case of both the above conditions is with a doppler ultrasound of the legs. This is an EXTREMELY important test which MUST be done AS soon as possible.

Swelling of the feet with change of color MUST be evaluated for lack of blood supply and my advice is to take her to the ER IMMEDIATELY. if this is NOT caught in time then it can lead to gangrene of the feet which can then only be managed with amputation of the feet.

The swelling etc can also be indicative of her heart not pumping adequately causing collection of fluid in the legs. but in either case a visit to the ER is recommended. But this is unlikely to be due to the oxygen.
