Re: Research: How to reduce lung residual volume?

Two methods you can use to estimate RV or at least changes in RV include:
- Changing ratio of full exhale static to FRC static
- Change in ballast required to reach neutral buoyancy at different depths without wetsuit
- Changing depth at which a full mouthfill is possible
Putting all the data here would take a long time. However, to consider some examples:
- In September 2005, starting my dive on FRC volume, I could perform a full mouthfill at a maximum of 9m of depth. Now, that has increased to 17m.
- In September 2005, my full exhale static was about 2'50". Now, my full exhale static is about 1'50", although my FRC static is about the same as it was in 2005.
I also know that my lung volume (inhale) without packing has decreased considerably, and my max volume with packing has decreased dramatically.
