My Dad has had to use 4L oxygen since a hospitalization for pneumonia last September. He was diagnosed with Alzheimer's March 2014 when he started hallucinating and having anxiety attacks with aggression. He has slept most of the time since 2013. He's at w VA home where the staff monitors him closely and gets him up as much as they can. He's eating fine, but I'm concerned about the pneumonia and sleeping. He doesn't interact with his dog or me much anymore either. He's also developed incontinence.
Also, there are some things he can do to improve his lung capacity. Our pulmonologist alerted us to a pulmonary/respiratory therapy program paid for by Medicare, with no limits as there are with PT. He can also use a nebulizer (available by script) as well as an incentive spirometer.
Someone might have to help him each time he uses the spirometer, but the nebulizer can be handled by a staff person.

I think the other issue is to explore with the treating pulmonary physician why he's getting pneumonia repeatedly. Is he bedbound, not getting much exercise or activity? Does he have COPD, emphysema?
