Hyperbaric chambers create conditions similar to those on the space station. Hyperbaric chambers are devices used to increase atmospheric pressure to more than one atmosphere, which can help treat various medical conditions. They can be used to simulate conditions at different altitudes, including the low pressure environment on the space station. Hyperbaric chambers are used to treat altitude sickness, decompression sickness, carbon monoxide poisoning, and other conditions. They can also be used to improve wound healing and treat chronic wounds.
