Abstract In order for astronauts to live and work in outer space, environmental conditions must be maintained within very strict parameters. Any change in these conditions (such as atmospheric composition, pressure, and/or temperature) could pose a risk to the astronauts and ultimately to the success of the mission itself. In particular, changes in pressure could place the astronaut at risk for decompression illness (DCI), a potentially life-threatening condition related to the presence of nitrogen bubbles within the body. There are a number of strategies in human spaceflight designed to minimize the risk of DCI or treat it if necessary. However, as humans prepare again to travel beyond Low Earth Orbit (LEO), the risk of developing DCI may increase, as would the difficulties in treating it, given that evacuation to Earth will become substantially less feasible. Even though hyperbaric oxygen therapy (HBOT) is the accepted gold standard for the treatment of DCI on Earth, there is currently limited capacity for this treatment option in space. Expanding HBOT capacity in human spaceflight could prove useful, given that this medical capability can also be used for the treatment of a number of other potentially life-threatening conditions, such as carbon monoxide poisoning, thermal burns, and gangrene. This paper will examine the current issues related to HBOT in space and discuss the opportunities for its use in future human spaceflight endeavors.

    Highlights Decompression illness occurs less frequently in space than would be predicted. Missions beyond Low Earth Orbit will involve partial gravity environments. Astronauts on such missions would likely have an increased risk of DCI. Technologies exist to deliver hyperbaric oxygen treatment in space. HBOT should be considered for future space missions beyond LEO.
