My new normal sucks

No other way to put it.

I got the new, larger concentrator last week.  I really believed the being able to turn it up to 8 liters to walk around would help but it doesn't.  I no longer feel like I want to pass out if I stand up but it hasn't helped nearly as much as I'd hoped.
SAT rate falls to the low 70's if I move at more than a crawl.

I should be getting a scooter this week.  Hopefully insurance won't drag it out too long.
