Mather Hospital's website describes the Hyperbaric Oxygen Therapy Unit in Port Jefferson, New York as the first HBOT unit on Long Island and currently the only one in Suffolk County available for emergencies 24 hours a day, seven days a week. Patients receive treatment in pressurized chambers delivering 100% oxygen, staffed by critical care nurses with hyperbaric physicians representing family practice, internal medicine, emergency medicine, pulmonology, and cardiology — three of whom are board certified in hyperbaric medicine. Conditions treated include decompression sickness, carbon monoxide poisoning, non-healing wounds (especially diabetic), soft tissue injury or infection due to radiation, preservation of skin grafts and flaps, sudden blindness from retinal artery occlusion, and abdominal radiation injury including enteritis, colitis, and proctitis after pelvic-organ cancer treatment.
