Which clinical sign indicates recovery from RDS?

The indication of recovery from Respiratory Distress Syndrome (RDS) primarily involves the positive changes in the infant's respiratory status and overall oxygenation. Diuresis, which is the increased production of urine, reflects a couple of significant developments in a neonate recovering from RDS.

As the alveoli in the lungs begin to open up due to treatment, such as surfactant therapy, and as the infant's lung function improves, it leads to better oxygen exchange and improves the overall alveolar stability. This improvement decreases pulmonary edema, allowing for better gas exchange and leading to the aforementioned diuresis. The kidney's response to improved oxygen delivery and decreased fluid overload results in increased urine output. Therefore, diuresis serves as a clinical sign that the infant is likely recovering, as the body is beginning to stabilize and function effectively.

In contrast, increased cyanosis, decreased respiratory effort, and prolonged apnea episodes are not signs of recovery but rather can indicate continued distress or complications, emphasizing the importance of evaluating multiple clinical indicators in the management of an infant with RDS.
