This is the most mysterious anesthesia circle system. Just relax and look at the blue gas moving back and forth in the circle system.

Take SLOW breaths in and out. It is important that you do this slowly.

Mysteriously, after some breaths, the blue gas will go one way with inspiration and go the other way during expiration !

If you stop breathing, it will loose track and again randonly move back and forth.

Have a go now. Take SLOW breaths in and out while looking at the blue gas …
