Medical diagnosis of pulmonary hypoplasia in utero may use imaging, usually ultrasound or MRI. [12] [13] The extent of hypoplasia is a very important prognostic factor. [14]One study of 147 fetuses (49 normal, 98 with abnormalities) found that a simple measurement, the ratio of chest length to trunk length, was a useful predictor of postnatal respiratory distress.

Pulmonary agenesis is an inborn lung underdevelopment that is rare and potentially lethal. [1] The disorder is caused by a complete developmental arrest of the primitive lung during embryonic life, and it is often associated with other developmental defects. [2]
Blood passes from the umbilical cord and flows into the left atrium through an opening called the foramen ovale; the foramen ovale is a hole between the two atria. [7] Once a baby is born and the lungs begin to fill with air and the blood flow of the heart changes, a tissue flap (somewhat like a trap door) called the septum primum closes the ...
Infants born with diaphragmatic hernia experience respiratory failure due to both pulmonary hypertension and pulmonary hypoplasia. The first condition is a restriction of blood flow through the lungs thought to be caused by defects in the lung.
Bochdalek hernia is one of two forms of a congenital diaphragmatic hernia, the other form being Morgagni hernia.A Bochdalek hernia is a congenital abnormality in which an opening exists in the infant's diaphragm, allowing normally intra-abdominal organs (particularly the stomach and intestines) to enter into the thoracic cavity.
Bronchopulmonary dysplasia (BPD; part of the spectrum of chronic lung disease of infancy) is a chronic lung disease which affects premature infants.Premature (preterm) infants who require treatment with supplemental oxygen or require long-term oxygen are at a higher risk. [1]

Despite only 1% of all birth complications being attributed to respiratory distress syndrome, there is a significantly higher prevalence in prematurely born babies. [39] Incidence rates of IRDS in premature infants born at 30 weeks of gestational age (GA) are at 50%, and rise even higher to 93% for infants born prematurely at 28 weeks of ...
