to inform readers about how he solved a problem
In the passage the speaker talks about how the tube was almost completely blocked with ice. He then speaks about how he was able to clear the ice from the tube by manipulating it. The problem was the ice in the tube and the solution was to bend the tube to get the ice out. He doesn't describe how it feels like to be without oxygen, or that he escaped somehow. It's not even clear from the excerpt that the tube is part of an oxygen mask.
