When explaining the status of a newborn who has persistent pulmonary hypertension to the parents, the nurse would integrate knowledge about the foramen ovale which is still open.
Pulmonary hypertension happens when the blood pressure in the arteries that connect the heart and lungs is too high. Lung blood vessels develop more muscle on their inner walls as a result of pulmonary hypertension.
Blood arteries in the lungs are constricted, obstructed, or damaged in pulmonary arterial hypertension (PAH), one kind of pulmonary hypertension.
Due to the injury, blood pressure in the arteries of the lungs increases and blood flow through the lungs is slowed.
During foetal development, blood can travel through the foramen ovale, a muscle opening between the left and right atriums, and skip the pulmonary circulation.
Hence, The nurse would provide information regarding the still-open foramen ovale when describing the condition of a newborn with persistent pulmonary hypertension to the parents.
