PAC | PAC Technology | Support | Cost & Ordering | Using a PAC

Using a PAC Th PAC is a simple piece of equipment but we would like to stress the importance of understanding how it works. We recommend reading the instruction manual thoroughly, watching the video of instructions and, if possible, having instruction from a trained person. Practice inflating/deflating the PAC before you use it, preferably with someone inside the PAC. If possible, have a go inside while someone else inflates/deflates it.

Inflated PAC

 Summary of operating instructions

NB. These instructions are not intended as a substitute for the instruction manual provided with the PAC.

A. Prepare the operating area (mats under and inside the PAC, place a sleeping bag in the PAC, arrange shade or cover the PAC with sleeping bags).

B. Connect the pump.

C. Close the variable pressure release valve.

D. Insert the altimeter into pocket inside window (optional).

E. Explain to the victim how the PAC works and how to equalise ear pressure.

F. Place the victim in the PAC.

G. Commence pumping and close the PAC zipper, keeping constant eye and voice contact with victim.

H. Pump rapidly until the PAC wall is tensioned, and then pump steadily to inflate (pressurise) the PAC. This is the equivalent of descending to a lower altitude.

I. If the victim experiences ear pain, open the variable pressure release valve and slow (or stop) pumping until the pain is relieved.

J. Once the PAC is fully inflated, the automatic release valve 2-PSI will start to hiss.

K. Raise the head end of the PAC by approximately 30º in cases of HAPE or HAPE.

L. Maintain the minimum pumping rate of one pump every 5 seconds until you start to deflate the PAC. (Short breaks of up to one minute are OK).

M. To end the treatment, open the variable pressure release valve and slow or stop the pumping. If ear pain occurs while deflating the PAC, close the variable pressure release valve (and give a few quick pumps) until the pain subsides.

N. When the PAC wall loses most of its tension, open the zipper completely.
