HBO Group started to serve by incorporating Oksimer in 1998, and Hipermer in 2001, private hyperbaric oxygen treatment centers. It is a treatment institution applied to thousands of patients from all over Turkey with non-healing wounds, osteoarthritis, diabetic foot, sudden hearing and vision loss, and stove-tube gas poisoning. In addition, it provides service to all professional and amateur divers who apply for diver examination and diving diseases, including sting.

During patient follow-up visits, friendly staff provide medical care and dressing. When necessary, it works with consultant doctors to provide treatment services with local surgical interventions.

Oximer and Hypermer hyperbaric oxygen treatment centers within the HBO Group use the Multiplace (10 4) human pressure chamber of the German Haux-Life-Support GMBH company, whose quality has been proven in international standards, for first class treatment.

HBO Group has commissioned the IT infrastructure hypernet system in Oksimer and Hipermer centers in order to strengthen its corporate structure and increase the quality of the services it provides to patients on a daily basis. Oksimer, which has an agreement with SGK, also provides services in agreement with many private health and complementary health insurances.
