The first multi-place hyperbaric chamber was built in 1965 in former Czechoslovakia. Currently, there are 9 multi-place chambers in Czechia and 7 in Slovakia. Despite the similar heritage in hyperbaric medicine in both countries, the situation differs nowadays. While hyperbaric medicine (HM) is recognized as post gradual specialization in the form of a functional course in Czechia, HM is not recognized as a medical specialization in Slovakia. The HM is taught at various levels to the medical student in Czechia, being included in other relevant subjects, such as internal medicine, sports medicine, or medical biophysics up to a self-standing semestral subject at the University of Ostrava. On the contrary, there is no formal education in this field, neither pre-gradual nor post-gradual in Slovakia as in allied health care and in medical professions. In addition, the pandemic lockdowns further restricted access for allied health professions, medical students, and physicians to the HM courses.
