The other type of chamber is the portable "mild" hyperbaric chamber. These soft vessels can be pressurized to 1.5-1.7 atmospheres absolute (ATA). They are only approved by the FDA for the treatment of altitude illness. The number of these chambers has increased, as they are being used more commonly in off-label indications.
