Dr. Hans Örnhagen

Hans Örnhagen, MD, PhD is research director and responsible for the naval medicine research at the Swedish Defense Research Establishment since 1992. He is also, since 1981, the consulting doctor to the Swedish Sports Diving Federation and he works as a consultant to PADI, and NAUI. To the Swedish sports divers he is known as the doctor running the free consultation phone, and that he initiated the work that led to the FTD routines now used by all diving schools in Sweden. Many of the instructors have read his textbook in Hyperbaric physiology and diving medicine although it is primarily aimed at the education of diving doctors for the Swedish navy, an activity that Hans Örnhagen has had on his agenda since 1977. He has published two more books and several scientific articles on mainly hyperbaric physiology topics ranging from liquid breathing and hydrogen diving to alternobaric vertigo in diving and breath hold diving.
