Persistent pulmonary hypertension of the newborn, or PPHN, is a life-threatening breathing issue that occurs when your newborn doesn’t adapt to breathing outside of your uterus. PPHN happens when your baby’s pulmonary arteries don’t open up enough, so your baby’s brain and organs don’t get enough oxygen.

2023年7月31日 · Persistent pulmonary hypertension of the newborn is a life-threatening condition in the immediate neonatal period. It may be due to lung parenchymal disease such as respiratory distress syndrome or due to underdeveloped lung vasculature in conditions such as congenital diaphragmatic hernia and small for gestational age infants.

How do we know if a baby has PPHN? Babies with PPHN need help with their breathing usually with a breathing tube and a breathing machine (ventilator). We can find out if a baby has PPHN with blood tests, a chest x-ray which tells us how the baby’s lungs look, and an ultrasound of the heart (also called ,cardiac echocardiogram or echo) which

2024年8月23日 · PPHN is also known as persistent pulmonary hypertension in the newborn and persistent fetal circulation syndrome. While in the womb, a baby receives oxygen from its mother and the...

Persistent pulmonary hypertension (PPHN) happens in newborn babies. It occurs when a newborn’s circulation continues to flow as it did while in the womb. When this happens, too much blood flow bypasses the baby’s lungs. This is sometimes called persistent fetal circulation. During pregnancy, a fetus' lungs don’t exchange oxygen and carbon dioxide.

Persistent pulmonary hypertension of the newborn (PPHN) is a dangerous condition that may cause a baby to not get enough oxygen after birth. During pregnancy, babies get all of the oxygen they from the mother through the placenta.

Persistent pulmonary hypertension of the newborn is a medical emergency in which immediate management is essential and is directed towards reversing hypoxemia, improving pulmonary perfusion by reducing PVR, increasing systemic pressures to reverse the right-to-left intracardiac shunting and minimising hypoxic-ischaemic end-organ injury.

Persistent pulmonary hypertension of the newborn (PPHN), previously referred to as persistent fetal circulation, is a syndrome of impaired circulatory adaptation at birth (1). The hallmark of PPHN physiology is sustained elevation of pulmonary vascular resistance (PVR) and persistent hypoxemia after birth (2).

Persistent pulmonary hypertension of the newborn, or PPHN, occurs when a newborn's circulation system doesn't adapt to breathing outside the womb. While in the womb, the fetus receives oxygen through the umbilical cord, so the lungs need little blood supply.

This information sheet from Great Ormond Street Hospital (GOSH) explains the causes, symptoms and treatment of persistent pulmonary hypertension of the newborn (PPHN). It also describes what to expect when a child is being treated at GOSH.
