Diagnosis

Various imaging and laboratory tests can help determine if a baby has persistent pulmonary hypertension of the newborn (PPHN). These may include:

• Chest X-rays may be recommended and can determine if the baby has lung disease or an enlarged heart.

• Echocardiogram, which is an ultrasound of the heart, can show whether the baby has heart or lung disease and evaluate blood flow in those organs.

• Ultrasound of the head may be used to look for bleeding in the brain.

• Arterial blood gas (ABG) determines how well oxygen is being delivered to the body.

• Complete blood count (CBC) measures the number of oxygen-carrying red blood cells, white blood cells and platelets.

• Serum electrolyte tests evaluate the balance of minerals in the blood.

• Lumbar puncture, also called a spinal tap, and blood tests can help determine whether an infection is present.

• Pulse oximetry, which measures oxygen levels in the blood, can help doctors monitor whether the baby's tissues are receiving an adequate amount of oxygen.
