There is no hyperbaric oxygen chamber. Generally, if you need hyperbaric oxygen, it is better to go to Hefei. You should be doing rehabilitation.
Even in Hefei, not all hospitals have hyperbaric oxygen. Neither the Provincial Hospital nor the First Affiliated Hospital of Anyi Hospital has hyperbaric oxygen chambers. Hua'an Brain Hospital Affiliated to the Clinical College of Anhui Medical University has hyperbaric oxygen. Hefei Second Hospital also has it. In terms of environment and equipment, Hua'an Brain Hospital is better. You can go and have a look first.
