It may be called atelectasis. I have that in the left lung, and an elevated diaphragm. Atelectasis can be caused by a number of factors, including after surgery, prolonged bed rest, pneumonia...My doctors were given results of the x-rays, including HBOT, but wasn't mentioned until I was having surgery. I start seeing my doctors next week again, so will address this. I do feel a more limited lung expansion.
