What are common diagnostic findings for IRDS/HMD?

Surfactant deficiency in premature infants causes alveolar collapse and diffuse atelectasis, so the lungs look hazy and glassy on imaging, with air-filled bronchi visible against the opacified alveoli. This ground-glass appearance with air bronchograms on chest X-ray is the hallmark radiographic finding for hyaline membrane disease. The gas exchange flaw leads to hypoxemia. In the early phase, many infants hyperventilate to compensate, so the arterial blood gas often shows low oxygen with a tendency toward respiratory alkalosis from increased ventilation. These CXR and ABG patterns together are the most characteristic clues for IRDS/HMD. Other imaging modalities like ECG, MRI, or ultrasound aren’t diagnostic for this condition and don’t typically reveal the key signs seen with surfactant deficiency.
