Is this nipple necrosis - do you think it will survive? (Photos)

I had my lift and implants 18days ago nipple was dusty purple ps said it was just congestion it's ok. It started to go pink around day 5 but has been getting worse I had doc apt nurse took tape off and ripped some nipple with it. She cut some dead skin off and did some blood release and taped it back up. Again I asked what is happening and they said congestion and will just take longer to heal. What steps should I take to insure that I have good outcome and proper care? Should I be airing nipple
