I too am on Oxygen 24/7 due to COPD. I am an RN with a BSN and have been struggling the last 5 years with my breathing issues. I tried many times to go back to work and all of them failed miserably because I ended up catching something from someone all the time. I just went back on Oxygen 24/7 just a few weeks ago, was only using it at night for a long time. My suggestion to you is to look into working in Utilization Review, Auditing, Telephonic Nursing, etc. If you start with these others will pop up. You can also put in Telecommuting Nurse or LPN and several opportunities should come up as well. More and more Nurses are doing this from home, this is known as "work from home". This is what I am getting ready to do as soon as I complete my certification in Medical Billing and Coding. I am getting this certification because in these types of positions I have mentioned I have to be familiar with billing and coding as I audit the computerized charting or workman's comp, whichever position I am going to take. I just have to have this certification. It might be worth looking into. I go to school online, I receive grants and student loans but it will help me get a better paying job. It only takes 10 months. I hope this helps.
