VI.Cardiac auscultation

Question

Quizplus · Accepted Answer

To differentiate between lung disease and congenital heart disease as causes of hypoxemia, a combination of tests is used. A chest radiograph (I) can show structural abnormalities in the lungs or heart. An EKG (II) can reveal heart rhythm issues or signs of heart disease. The hyperoxia test (III) helps determine if the hypoxemia improves with oxygen, indicating a lung problem if there's no improvement, or a cardiac issue if there is. An echocardiogram (V) directly visualizes the heart to detect congenital heart defects. Cardiac auscultation (VI) can reveal abnormal heart sounds indicative of heart disease. Pulmonary function tests (IV) are specific to lung function and not directly used to differentiate between lung and congenital heart diseases in the context of hypoxemia.
