Altitude room at local gym - thoughts?

Actually, that makes me wonder now, would having an “altitude room” at sea level that simulates say -5000ft allow you to work even harder make sense? So if you live low, you can train REALLY low?

Back when I was an EMT a couple of my coworkers would breath off the O2 tanks for a bit (not long) if they were sleepy. I never tried it myself but they said it helped (briefly).
