Pulmonary hemorrhage (or pulmonary haemorrhage) is an

positive pressure ventilation, and correction of underlying abnormalities such as disorders of coagulation. A blood transfusion may be necessary.[1]

Causes

breech delivery, hypothermia, infection (like pulmonary tuberculosis), Infant respiratory distress syndrome (IRDS), administration of exogenous surfactants (in some studies) and extracorporeal membrane oxygenation (ECMO).[1]

Pathophysiology

Although the

plasma proteins, high alveolar surface tension, lung damage, hypervolemia).[1]

Diffuse alveolar hemorrhage

Diffuse alveolar hemorrhage is bleeding from many alveoli throughout the lungs. Common causes include autoimmune diseases and connective tissue diseases.[2] Diagnosis of DAH is often given following observation of a patient presenting with hemoptysis, anemia, and cough,[3] along with a chest X-ray showing alveolar infiltrates in the lungs,[4] which are areas of air space in the lungs that are opacified and of higher density that normal, usually indicating that they are filled with a substance such as pus, blood, or another fluid.[5]

Incidence

The outcome of treatment is dependent on causality. Pulmonary Hemorrhage is present in 7 to 10% of neonatal autopsies, but up to 80% of autopsies of very preterm infants.[1] The incidence is 1 in 1,000 live births.[1] Pulmonary hemorrhage has a high mortality rate of 30% to 40%.[1]
