First, I want to emphasise that this is not a critical situation in light of the patients injuries. This is more of an exercise in mental masturbation with all the trauma stuff thrown in as a distraction. Also, this is somewhat of a novel concept; however, I know of at least one case in the literature.
There exists a physical concept known as the Coanda effect. It essentially states that in some situations a fluid will have a tendency to attach to a surface and follow the said surface. Fluid in a physical sense can be a gas or a liquid as both have fluid like characteristics when in motion. An easy do at home example of this effect involves a candle and a can of soup. Light the candle and put it in front of the can of soup. Blow a stream of air on the other side of the can. Conventional wisdom says the can should stop the flow of air. However, the air attaches to the surface of the can and contours around it to blow the candle out.
In this case, the deviation placed the ETT near or on the right tracheal wall. The flow of air attached to the wall and followed it into the right lung. Then, as the lung filled, the air essentially spilled over into the left lung so to speak. This is what led to the asymmetrical expansion I have a rather bad drawing attached to better view the effect. An art major I am not:
In the actual case stude, the provider rotated the ETT by about 90 degrees and was able to resolve the asymmetrical movement problem.
I hope you guys enjoyed this one as it was a little different, but still thought provoking hopefully.
Take care,
