could anyone explain what basal atelectases in base of lungs means please?

Question

On CT scan emphysemia was found as well .I am a smoker who is now giving up.

Answer 1

Atelectasis is a "weakening" of the alveolar sacs in the lungs, they tend to colapse slightly if you don't take deep breaths. This can lead to pneumonia. Congrats on quitting!!!
Emphysema is a lung disease, that can complicate atelectasis. Suggest you go to a pulmologist, and have a pulmonary function test PFT. Also while your trying to quit,
do coughing and deep breathing excersizes to help you gain strength in the lungs and reinflate those alveoli. Good Luck!!
