• Make sure all the pressure gauges are reset to zero except the O2 pressure

gauge.

• Switch off O2 supply.

• Make sure the O2 pressure gauge is reset to zero. The low O2 supply alarm

should be on when pressure drops.

2 Make sure cylinders are fully filled:

• Open each cylinder valve.

• Make sure the pressure of each cylinder is high enough. In case the pressure is

insufficient, close the corresponding cylinder valve and install a fully filled
cylinder.

6) Perform the preoperative check.

2 Sterilizing

Cleaning and sterilizing must be performed at the same time. Follow instructions for the
common bellows assembly sterilization methods.

Sterilizing after general patient use:

Clean the inner and outer parts of the bellows assembly in a soap-and-water solution. Rinse
thoroughly in cold water, and dry with soft cloth. Immerse plastic and latex instruments in
70-80% ethyl alcohol for half an hour. Take them out using the aseptically transmits pliers, then
store in clean containers. Repeat this step before next use. Components made of metal and
glass can be sterilized with high pressure steam. When the steam pressure is increased by the
autoclave, the rising temperature can concrete the bacterium protein rapidly to kill bacteria. In

1.05 KG/CM2 steam pressure, the temperature rises to 121C. All bacteria and most sorus can

be killed if this temperature is maintained for 15-25 minutes.

Sterilizing after special infection or infectious patient use:

Open pulmonary TB, pulmonary abscess, pseudomonas, tetanus aeruginosa infection, gas
gangrene or infectious hepatitis is included. Used bellows assembly components must be
completely sterilized according to preliminary and final disposal procedures.
