The PAC is a result of intensive research and development by Dr Jim Duff and Roddy Mackenzie, who between them have been on four Everest expeditions. It is designed to be as simple to use as possible, while being robust enough to stand up to the tough conditions in the mountains.
PAC technology has been shown to be highly effective in reversing symptoms of altitude illness. Depending on the starting altitude, simulated descents of approximately 2000 metres (6000 feet) are achieved at the operating pressure of 2 PSI above ambient pressure.
For an independent review of hyperbaric bags, see Dr Dietz’s site (note: prices mentionned are incorrect).
The PAC has been designed to be as simple as possible to operate. One person can perform a complete treatment cycle. A summary of the instructions is printed on the PAC itself, while all the valves are clearly labeled to avoid confusion. Comprehensive instruction manuals can be downloaded from our website, in various languages.
Made from tough, reinforced PVC, the chamber is robust and designed to withstand the rigours of the mountains.
The PAC, all up with pump, hose, repair kit and storage bag, weighs in at approximately 8 kgs.
We are committed to making this technology affordable and we believe we have done so.
The PAC comes in three versions:
1. An English version – English instructions on the PAC (full English instruction manual downloadable from our website).
2. An English/ Nepali version – instructions on the PAC in both languages (full English and Nepali instruction manuals downloadable from our website).
3. An English/Chinese version – instructions on the PAC in both languages (full English and Chinese instruction manuals downloadable from our website). These PACs are manufactured upon request.
Large Windows – to help maintain visual contact
Tapered Shape – maximizes the space around head and shoulders
Circumferential Zip – helps the victim to get in and out of the PAC easily
Automatic Release Valve – set at 2.0 PSI, which simulates a descent of approximately 2000 metres at an altitude of 5000 metres
Variable Pressure Release Value – to control the rate of inflation/deflation
External Anchor Point – for security on steep ground
Accessories: includes repair kit, pump and carry bag
