Thanks for your question on Healthcare Magic.
I can understand your concern.
Lung function of 92% is considered very good.
So no need to worry for death or any disease.
Mild paraseptal
emphysema on CT is mostly an accidental finding.
If you don't have any symptoms (breathing difficulty,
cough, expectoration) then no need to worry for mild paraseptal emphysema.
Avoid
smoking, alcohol, maintain good health by exercise.
No need to worry for death after 4 years.
Yoi will definitely be good.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
