Submembranous interstitial changes mostly refer to lung infections or interstitial pneumonias and are an imaging concept.
Submembranous interstitial changes usually show ground-glass shadows, honeycomb, linear, or fibrotic shadows on imaging. They are mainly due to lung infection and interstitial pneumonia.
Usually, symptoms such as cough, wheezing, chest tightness, shortness of breath, and dyspnea are present in subpulmonary interstitial changes. As the disease progresses, life-threatening respiratory and heart failure may occur.
If the test results show subpulmonary interstitial changes, you should consult a doctor as soon as possible to identify the specific cause of the disease, actively cooperate with the doctor to give targeted treatment, and give oxygen-assisted ventilation therapy when necessary to avoid missing the best time for treatment.
