Yes: Think about americans who live in denver, sherpas that live in tibet, & the maya in south america. These are populations of people who have become accustomed in one way or another to a lower atmospheric oxygen level, and in the mayans a lower blood oxygen level. Another sea-level example would be a person with emphysema who may run a blood oxygen level of 88% and still be walking around home depot.
