We really don't. Most of the increase in respiratory rate has to do with
acid/base balance. Put simply: exercise-lactic acid-blood pH drops-breathe
fast-blow off carbon dioxide-blood pH rises: compensatory
hyperventilation.

As John suggested, a good doctor and a complete workup might be warranted.
He did mention clearance from a cardiologist.
Yes, but he also mentioned allergies and asthma. Additionally, causes of his
symptoms could be due to various systems: neurological, endocrinological (is
that a word?), respiratory, dermotolog...uh, no, scratch that last one.

first started training that I'd get dizzy and nearly pass out almost
every workout. The workouts I do now would surely have killed me,
literally, back then.
I had an interesting discussion with a guy at the gym about this. I
was doing deadlifts without much weight and when I put it down I
mentioned how my lungs gave out before my muscles did. He said that
his muscles would give out before his lungs did. These are obviously
subjective statements but were interesting to me because of the
perceived difference in source of exhaustion.
Makes the concept of training to failure rather problematical.

In the end, he might just be in poorer shape than he thinks he is. I'm
only taking 90seconds rest between sets (alternating exercises, 5-8
reps, sometimes to failure: this week is my final week at 8-8-8 for my
work sets before upping the weight and dropping back to 5-5-5 for each
exercise) and my Hb today is 7.9 (the weights even come after 20 minutes
on the bike with my heart rate between 152 and 161 bpm). During heavy
squats I certainly had to take longer rest periods, but I can't do those
anymore. Taking half an hour before being able to continue does sound a
bit suspect, though, in terms of some underlying medical condition.

I'm going to die rather sooner than I'd like. I tried to protect my
neighbours from crime, and became the victim of it. Complications in
hospital following this resulted in a serious illness. I now need a bone
marrow transplant. Many people around the world are waiting for a marrow
transplant, too. Please volunteer to be a marrow donor:
