Can narcotics contribute to the development of pneumonia?

I take prescribed narcotics for a medical condition. I have had pneumonia twice now. Any corelation between narcotics and pneumonia? I thought perhaps the depression of breathing might be a factor but cannot find anything about it. Also, my oxygen sat was very low in the hospital....52%; I also have asthma, copd and chronic bronchitis. Any way to keep oxygen levels up?

My oxygen sat was 80% in the hospital. My blood oxygen level was 52% and 81%. Sorry for the confusion. Also, the drug I take is Opana; 60 mg twice a day. Thank you

If your O2 sat is 52% and you are awake, you have had significant lung disease for a number of years. Narcotics do not cause pneumonia directly. But, they do decrease your urge to cough, which in turn can cause a build up of secretions in the bases of the lungs, thus causing the risk for pneumonia to increase.
You do not list the narcotic you are taking, or the dose, so I would need to know those to give you a better answer.
I am going to assume that you do not currently smoke, and that you stay faraway from 2nd hand smoke. If you do smoke stop TODAY!!!!
You need to be under the care of a good internal medicine doctor or a pulmonologists(lung doctor)
