Hypobaric chambers, also known as altitude chambers or low-pressure chambers, are specialized rooms or chambers designed to simulate high altitude conditions. These chambers are commonly used in the aviation and aerospace industries for research, testing, and training purposes. Furthermore, there are also other synonyms for hypobaric chambers, such as decompression chambers, low-oxygen chambers, low-altitude chambers, and altitude simulation rooms. Regardless of the term used, these chambers mimic the air pressure and oxygen levels that one would experience at higher altitudes, providing a controlled environment to study the effects of altitude sickness, decompression sickness, and other physiological responses to changes in atmospheric pressure.
