Complications PPHN can range from mild to severe disease. In the most severe form, infants experience severe hypoxemia resulting in cardiac and pulmonary complications. As a result of low oxygen levels, infants with PPHN are at an increased risk of developing complications, such as asphyxia, chronic lung disease, neurodevelopment issues, and death. Nosocomial infections are another type of complication that may contribute to mortality in someone with PPHN. If the newborn acquires an infection while hospitalized, this could result in deterioration of the condition even after days of improvement.
