What is the expected duration of RDS before resolution?

• A. 1-3 days
• B. 1 week
• C. 2 weeks
• D. 3-4 weeks

Answer: (B)

The expected duration of Respiratory Distress Syndrome (RDS) in neonates typically resolves within approximately 1 week. RDS is primarily caused by surfactant deficiency in preterm infants, leading to impaired gas exchange and effortful breathing.

With appropriate management, including oxygen therapy and possibly surfactant replacement therapy, most infants experience significant improvement within a few days. By the end of the first week, the infant's respiratory function generally stabilizes and they usually show considerable clinical improvement.

Although some cases may take longer, especially in more severe instances or in infants with additional complications, the standard timeline of resolution for uncomplicated RDS is around 1 week. This aligns with clinical observations and management protocols within neonatal care.
