Does RDS cause atelectasis?
PATHOPHYSIOLOGY: The primary cause of RDS is inadequate pulmonary surfactant. The structurally immature and surfactant-deficient lung has ↓ compliance and a tendency to atelectasis; other factors in preterm infants that ↑ the risk of atelectasis are decreased alveolar radius and weak chest wall.
How does RDS relate to atelectasis?
In RDS, the lungs are hypoaerated, and the abnormal lung opacities due to atelectasis are finely granular. In addition, pneumothorax related to RDS is often under tension, and surgical intubation is required.
What is the pathophysiology of RDS?
RDS is caused by developmental insufficiency of surfactant pro- duction and function, as well as by structural immaturity of the lungs. It can also result from surfactant protein genetic disorders. This review discusses the pathogenesis of RDS in relation to fetal lung growth and surfactant metabolism.
How is RDS in neonates diagnosed?
Diagnosing NRDS blood tests to measure the amount of oxygen in the baby’s blood and check for an infection. a pulse oximetry test to measure how much oxygen is in the baby’s blood using a sensor attached to their fingertip, ear or toe. a chest X-ray to look for the distinctive cloudy appearance of the lungs in NRDS.
How is RDS treated?
Oxygen therapy to raise the oxygen levels in your blood is the main treatment for ARDS. Oxygen can be given through tubes resting in your nose, a face mask, or a tube placed in your windpipe. Depending on the severity of your ARDS, your doctor may suggest a device or machine to support your breathing.
What causes RDS in infants?
Neonatal RDS occurs in infants whose lungs have not yet fully developed. The disease is mainly caused by a lack of a slippery substance in the lungs called surfactant. This substance helps the lungs fill with air and keeps the air sacs from deflating. Surfactant is present when the lungs are fully developed.
What are 5 other immediate complications of RDS?
These may include atelectasis; leakage of air from the lung into the chest cavity, called pneumothorax, a type of pleural disorder; and bleeding in the lung, or hemorrhage. Some of the life-saving treatments used for RDS may cause bronchopulmonary dysplasia. Patent ductus arteriosus, a type of congenital heart defect.
Is RDS fatal?
RDS can be fatal. There may also be long-term complications due to either receiving too much oxygen or because organs lacked oxygen. Complications can include: air buildup in the sac around the heart, or around the lungs.
