Hyperbaric Oxygenation Treatment and Quality of Life

"Participants in this study will receive hyperbaric oxygen treatment (HBOT) but the investigators do not assign this specific intervention to the study participants. Thus, the patients in this study will receive HBOT as part of routine medical care. Consequently, we regard this as an observational study because the patients will get HBOT independently of the study and they are NOT assigned prospectively to HBOT according to a protocol to evaluate the effects.~HBOT for pelvic radiation injury typically involves a treatment pressure of 2.4 ATA (Atmospheres Absolute) breathing oxygen for 90 minutes. The treatment is delivered as series treatment, usually daily treatment up to 30 dives."
