Portable oxygen concentrator???

[Sabot]

I’m taking a group of guys to Colorado this year. We are all flat landers and have all been to Colorado before, but we are going to be at 10,000 feet and I’m a little concerned that we could have an altitude sickness issue that ruins the trip.

Has anyone ever brought, used a portable oxygen concentrator as a supplement or for emergency use?

We’ve used canned oxygen and taken the prescription pills before as well.

thanks in advance for your input
