compare chest x-ray one week apart

these are the 2 x-ray info. please let me know what this means and also what is unremarkable regional bones FOR AGE?

Findings- there is generalized lung hyperaeration likely attributed to deep inspiration with no acute pneumonic infiltrates or edema present. The cardiac silhouette is within normal limits in size. Regional bones are unremarkable for age.
Impression- lung gyperaeration without other radiographic abnormalities demonstrated.

next e-ray one week later

comparison is made to previous examination

findings- the cardiac silhouette pulmonary vasculature is normal. the lungs are free of consolidation, obvious effusion. there is no evidence of a pneumothorax. There is mild hyperinflation.
Impression- mild hyperinflation, otherwise no acute pulmonary disease

I suspect the term “regional bones” is a mistake.  Visualizable bones may have been the original meaning.
Hyperaeration, or hyperinflation of the lungs means air is trapped in the small airways so the lungs appear larger than usual on the chest x-ray.  This simply means that you were breathing hard when the chest x-ray was taken.  In the short term, it really does not mean anything serious.  This is a very common finding when asthma is poorly controlled, like during an asthma attack.  This same finding is seen in the lungs of chronic smokers.  It can also be due to a virus.  
This all sounds very normal.
