what keeps the airway open on expiration?

Just to present an alternative perspective...

This is extremely difficult to do so if you are frail don't attempt this.

We normally consider chest expansion and drawing air in as inhalation. Everything relaxes and air goes out during exhalation. Some breathing exercises focus on forcing more air out than what is involved in normal expiration.

If you cycle between forcing air out, then relaxing to draw air in you end up with somewhat of a reverse cycle. Effort to blow air out and relax to breathe in.

This is totally not natural and I don't think you can do it in your sleep, but it is fun to play with breathing. I can only do this for a very short period of time. I find it interesting to observe that either way of breathing, normal or reversed, while awake has no change on my O2 levels as long as I am resting and not engaged in any activity.

If you don't mind I would like to use that in my rotation of party games.

Man, Hosecrusher you are one "wild and crazy guy".
You can think up some stuff for sure.

Feel free to use it anyway you want. This originated from trying to illustrate how a submarine submerges for my children. I would be floating in the water and they would measure my "free board." Then I would over inflate my lungs and ended up floating a little higher. Blowing all the air out and forcing more out would drop me lower in the water.

I survived being pushed under, being tickled, being jumped on for rapid submersion, and am still alive. The children had a great time reporting all of this to their science teachers. We ended up needing more data so I had to blow into a plastic bag to get an idea of the volume of air involved. After blowing several times I got a little dizzy but we needed 5 data points to take an average. Then estimating the amount of body out of the water and the changes observed the science teacher was able to determine the bouyancy of my personal "boat."

The humorous part of this is that while I have some fat my children were skinny as can be. They could not float without paddling and were unable to measure their own results.

At that time I help out with the science class and as a result of this I ended up being known as Mr. Submarine Man... At the end of the year everyone in the class had some understanding of buoyancy.

Now you have the "rest of the story."
