Read guidesWhat Is Hyperbaric Oxygen Therapy?
Hyperbaric oxygen therapy (HBOT) is a medical treatment in which a patient breathes 100% oxygen inside a pressurized chamber. The increased pressure allows your lungs to absorb significantly more oxygen than at normal atmospheric pressure, which promotes healing and fights infection.
HBOT has been used in clinical medicine for decades. Device clearance, clinical indications and insurance coverage are separate questions; research continues into additional applications.

Hyperbaric Oxygen Therapy for Depression: What the Research Shows (Investigational)
HBOT for depression is investigational, not FDA-approved. Depressive symptoms have only been measured as a side outcome in PTSD and fibromyalgia trials. Here is what that evidence does and does not show.
Hyperbaric Oxygen Therapy for Peripheral Artery Disease (PAD)
HBOT for chronic PAD and claudication is investigational, not FDA-approved, and not covered by insurance. Here is what the evidence shows and how it differs from covered wound care.
HBOT for Hemorrhagic Radiation Cystitis After Pelvic Radiation
Blood in the urine months or years after pelvic radiation can mean radiation cystitis. HBOT is an FDA-approved option supported by the RICH-ART trial.
Hyperbaric Oxygen Therapy and Diabetic Neuropathy: What the Evidence Shows
HBOT is approved for diabetic foot ulcers, not for neuropathy symptoms alone. That distinction decides coverage. Here is what the research really shows.
Hyperbaric Oxygen Therapy and Erectile Dysfunction: Reviewing the Research
HBOT for erectile dysfunction is investigational, not FDA-approved. One small 2018 study drove the interest. Here is what it found and what it didn't.
Hyperbaric Oxygen Therapy and Tinnitus: What the Evidence Shows
HBOT for tinnitus is investigational, not FDA-approved, and not covered by insurance. Controlled evidence shows no clear benefit for chronic ringing in the ears.
