Diagnosis typically involves a combination of clinical evaluation and diagnostic tests:
1. Clinical Signs: Rapid breathing, grunting, flaring nostrils, and retractions (inward movement of the chest wall) are common signs. 2. Pulse Oximetry: Used to measure oxygen saturation in the blood. 3. Chest X-ray: Helps identify structural abnormalities, fluid in the lungs, and other issues. 4. Blood Gas Analysis: Measures oxygen and carbon dioxide levels in the blood, indicating how well the lungs are functioning. 5. Echocardiogram: Used to assess heart function and identify conditions like PPHN.
