Persistent Pulmonary Hypertension of the Newborn

There are many ways that they can diagnose PPHN, but I want to start off by informing you about the laboratory testing that they use. Starting with Arterial blood gas levels also known as ABG. ABG tests are used to measure the levels of carbon dioxide and oxygen in the blood from an artery. The blood is always taken from an artery. It must be used from an artery due to the fact that in veins the oxygen has already been used up and carbon dioxide is present (Lung Disease & Respiratory Health center, 2012). Next diagnosis could possibly be done by blood count with differential. This test is done to test if an extreme infection or illness is the cause of the PPHN. Some of the infections and illnesses listed in the causes section can be determined by this test. Coagulation studies are also used to determine if there are dangerous infections present in the system that could potentially harm the fetus. Lastly, for laboratory tests is the serum electrolytes scan. This is to determine the levels of potassium and calcium that is released during the trigger event of PPHN. Since your carbon dioxide levels go up and oxygenation goes down you begin to release more potassium and calcium to trigger faster breathing and a quicker heart rate to disperse the CO2 and intake more oxygen (Ellis, 2014).

Next, I would like to discuss the imaging studies that can be done to help diagnose PPHN of the newborn starting with chest radiography. This is used to see if there are any lung diseases such as meconium aspiration syndrome or pneumonia. This scan also rules out potential congenital defects that could potentially be causing the same symptoms as the ones we were investigating. Next, I would like to explain echocardiography. There are used to map out ...
