Must measure metHb levels (especially with prolonged exposure at 20 ppm). That's because it's secondary to another problem, such as a left heart or lung disorder. It's most commonly caused by a large hole in your heart between the two lower heart chambers (ventricles), called a ventricular septal defect. After infants are delivered, their lungs must begin to function outside of the their mother's womb, exchanging oxygen and carbon dioxide. The blood pressure measured by a cuff on your arm isn't directly related to the pressure in your lungs. Persistent pulmonary hypertension in the newborn (PPHN) occurs in babies soon after birth.

Maximize oxygen-carrying capacity with PRBC transfusion. Failure to decrease PVR leads to right to left shunting at the atrial and/or ductal level; resulting decrease in pulmonary blood flow leads to hypoxemia and myocardial dysfunction. The heart valves, which keep blood flowing in the right direction, are gates at the chamber openings. may cause a pulmonary over-flow state leading to congestive heart failure. Despite growing awareness of the clinical importance of pulmonary hypertension (PH) in preterm infants, uncertainty persists regarding the different clinical settings in which abnormalities of pulmonary vascular growth, function, and structure contribute to high morbidity and mortality, and potential interventions to improve outcomes are uncertain.
