hypobaric
Below normal pressure
Hypobaric describes conditions of lower-than-normal atmospheric pressure.
The term appears in aviation and mountain medicine, where reduced pressure affects oxygen availability: hypobaric hypoxia, hypobaric chamber.
A hypobaric chamber simulates high-altitude conditions for training or research.
The opposite is hyperbaric.
