Who is not allowed to accompany patients during hyperbaric oxygen therapy?
Hyperbaric oxygen therapy (HBOT) serves as an effective adjunctive treatment for traumatic brain injury, cerebral infarction, and hypoxic encephalopathy.

During HBOT, patients breathe 100% oxygen inside a sealed hyperbaric chamber pressurized to approximately 2 atmospheres absolute (ATA). Each session lasts about two hours. Pressure must be gradually increased before sealing the chamber and gradually decreased before opening the chamber door; patients must remain inside the chamber throughout the entire session.

Patients who are unable to care for themselves or whose condition is unstable require an attendant. Individuals with contraindications to hyperbaric oxygen therapy—including those with epilepsy, active respiratory infections, ear or nasal disorders, or claustrophobia—are not permitted to enter the chamber, nor are they recommended as attendants.
