### input:
I have just come home from my 6 th hospitalization this year. 4 have been pneumonia related, 2 were from new A-Fib which I developed from my first bout with pneumonia on 25th of Jan. in April, I checked into ER with A-Fib again. 3 days later I had bilateral pneumonia. When I went to ER, I didn t even have tickle in my throat. My question centers around my oxygen. After 3 weeks in April in Chandler Mercy Hospital, they sent me to a therapy Hospital. When I went I was at a flow rate of 15. After 3 weeks I was back down to 2 during the day and 4 in pm. My oxygenation is 96/97 with oxygen and heart rate is 65/75. If I go off the oxygen, I drop to low 80 s and even 70 s with heart rate in 90 s. Doctor am I able to look forward to getting off oxygen? Prior to this year I be not been in hospital since 2001 for appendix and 2004 for pneumonia but no oxygen!

Thanks for your question on Chat Doctor. In my opinion you should consult pulmonologist and get done1. CT THORAX2. Bronchoscopy and BAD (Bronchi Alveolar Lavage) analysis3. PUT (Pulmonary Function Test). Pneumonia can happen in both lungs, but it is not common. I think we need to rule out interstitial lung disease (OLD) and chronic congestion first. As possibility of these are high. So CT THORAX and PFT is needed to rule out this. If in CT pneumonia is seen than get done Bronchoscopy and BAD analysis for identification of causative organism and start treatment accordingly. So better to consult pulmonologist and discuss all these.
