Pneumonia: Primary lung infection most commonly means pneumonia. Regression means that the infection has decreased since the last study. Hyperaerated lungs can mean that the patient took an intentional deep inspiration or that there is air trapping due to airway blockage, which can be due to asthma, COPD, and other causes.
