Frequently asked questions

HBOT is used in medicine for selected indications, but like any treatment it has risks. Prior assessment and medical supervision are essential. Possible adverse effects include ear and sinus discomfort or injury, temporary visual changes, fatigue and, rarely, more serious complications such as oxygen toxicity or barotrauma. Discuss your individual risks with the clinician.

Untreated pneumothorax is a major contraindication. Other situations, including some lung conditions, recent ear surgery, seizure history, pregnancy or certain medicines, require careful assessment and are not automatically absolute contraindications. Disclose your full medical history and all medicines.
