A portable and compact hyperbaric chamber includes an inflatable chamber, a weighted base, a dump valve, at least one auxiliary port, an external pressure gage, a plurality of fill valves, and a plurality of pressure relief valves. The access opening is integrated into a lateral panel of the inflatable chamber and provide in and out access to the inflatable chamber. The weighted base is mounted to the base panel and functions as a stable base. The plurality of fill valves is in fluid communication with the inflatable chamber to provide compressed air from a compressor so that the inflatable chamber can be pressurized. The plurality of pressure relief valves is in fluid communication with the inflatable chamber to maintain a specific pressure within the inflatable chamber. The dump valve, the auxiliary port, and the external pressure gage are in fluid communication with the inflatable chamber to optimize the functionality.
