You need to discuss this with your doc. If you don't have a pulmonologist, get one. Ask about Pulmonary Rehab. Part of your problem is that you're terribly de-conditioned, and you need to build your strength. We've seen people come to PR in wheelchairs and walk out under their own power. It takes work, but you probably can increase your own comfort ad independence by putting forth some goo hard effort in a PR program. There may be many other things a good pulmo could do for you, including different meds, O2 therapy, etc.

thanks for the help everyone see the doctor in 2 weeks.

Sorry to hear this. Keep drinking lots of water to loosen secretions and learn purse lip breathing. It will help. And make sure to appreciate your wife's help !! You are a lucky man having a wife that helps you.

Thank you ladies i will tell you later how i got or get on

Alana, you must have a machine that plugs into electric plug on the wall. It makes its own oxygen. The one you are talking about is a portable machine, which has to have refills. Do ask your doctor about this one. But get one with a nebulizer on, its a huge help to nebulise twice a day. Take care and better breathing.
