...I had read where COPD patients should breathe out through pursed lips to allow more oxygen a chance to get in their blood stream. I kept this in mind in the hard places at high altitude and it seemed to help. I'm not a medical professional at all but would love to hear someone else's opinion on this...

Yes, it does work for me.
Congratulations to both on your summit!
What? No burger or beer?
Have fun...
