People with COPD are told not to scuba dive because of the danger of additional lung damage. I think the issue with decompression chambers and damaged lungs is that these are normal lungs that have been exposed to greater depths than they should have and has to do with exchanging gases, not actually "healing" lungs that have been damaged. On the chance that there's something to this, you can certainly ask your doc!

On with the Decompression Chamber and damaged lungs discussion . Would it be possible to add medication in a chamber where one could breathe in the medication - not unlike a nebulizer but a different medication ? I'm sure it would be costly but , once someone was able to figure out the medication and the delivery , we would be set !
