Tests
How is HMD diagnosed?
HMD is usually diagnosed by a combination of assessments, including:
- appearance, color and breathing efforts (these signs indicate your baby's need for oxygen)
- x-rays of lungs – x-rays are electromagnetic energy used to produce images of bones and internal organs onto film. In HMD, they often show a unique “ground glass” appearance called a reticulogranular pattern.
- blood gases (tests for oxygen, carbon dioxide and acid in arterial blood) - often show lowered amounts of oxygen and increased carbon dioxide.
- echocardiography (EKG) – may be used to rule out heart problems that could cause symptoms similar to HMD. An electrocardiogram is a test that records the electrical activity of the heart, shows arrhythmias or dysrhythmias (abnormal rhythms) and detects damage to the heart muscle.
