Find a flat ,safe and suitable area free from sharp objects and unroll the chamber. 

Place some padding on ground if handy ie: a sleeping mat.

Lay chamber out of top of matting and attach the foot pump.

Recommended things to take inside with the recipient: pee bottle, phone/ communication device, alti watch, water, warm clothing, possible means to escape in an emergency such as a pocket knife.

Put the person and items inside, zip up the bag, begin pumping at a steady rate

Once pressurised the bag will become very taught and full, continue pumping to maintain pressure and give the recipient fresh oxygen. Continuous pumping is required for 45minutes to 1 hour.

Maintain communication at all times and check in regularly with the person inside. 

If a positive result is achieved - ie: the person inside is coherent and begins to feel better, you can continue to pump for longer if the situation allows.

To deflate the bag do so slowly. Reduce pump rate, ask the recipient to put their finger in the pressure relief valve and begin to gently bring the air pressure back to ambient over a course of minutes. Slowly break the seal on the zip by opening zipper slowly.

In the event that the person inside is unable to relive the air pressure pull zip carefully until there is an audible hiss, stop and wait for the pressure to come down before fully opening

Remove person and contents, turn bag inside out and hang to dry.
