The pressure chamber concept has been around for many years, yet the majority of trekkers and mountaineers going to high altitudes do so without this essential piece of safety equipment.

The PAC is an affordable, durable and reliable means to assist reversal of high altitude illness symptoms (AMS, HACE and HAPE). If conditions do not allow for an immediate and effective descent, or the patient is too ill to move, the use of the PAC can be a viable alternative.

The (PAC) was developed in 1996, combining the expertise of Roddy Mackenzie, Dr. James Duff and C. E. Bartlett Pty. Ltd. The Portable Altitude Chamber (PAC) is an Australian made product for export, aimed at trekking groups, both private and commercial, as well as expeditions to high altitude. It aids the need for an effective, simple, durable, lightweight and affordable pressure chamber to assist reversal of AMS symptoms.
