What does TTN stand for in neonatal respiratory care?

• A. Transient Tachypnea Of The Newborn
• B. Transient Tachypnea Of Neonate
• C. Temporary Tachypnea In Neonate
• D. Tonic Tachypnea Of The Newborn

Answer: (A)

TTN stands for Transient Tachypnea of the Newborn. This is a self-limited respiratory distress that happens when a newborn has delayed clearance of fetal lung fluid after birth, leading to tachypnea and mild work of breathing. It most often occurs in term or near-term infants and is more common after cesarean delivery, where labor helps push fluid out of the lungs. The condition typically begins within the first hours after birth and improves as the fluid clears over 24–72 hours, with supportive care such as supplemental oxygen or CPAP if needed. Chest radiographs may show mild hyperinflation with prominent perihilar markings. The other phrasings—neonate, temporary tachypnea, or tonic tachypnea—do not reflect the standard terminology used for this condition.
