We study the effects of oxygen pressure in patients treated with hyperbaric oxygen therapy, and healthy humans in extreme environments.
Hyperbaric oxygen therapy (HBOT) is a clinical method used for 14 different diagnoses where oxygen is given at 240-280 kPa (compared to breathing room air ~21kPa or breathing pure oxygen ~100kPa). The chamber is located at the Karolinska University Hospital in Solna.
