Related to transient tachypnea of the newborn: respiratory distress syndrome


very rapid respirations, seen especially in high fever when the body attempts to rid itself of excess heat. The rate of respiration increases at a ratio of about eight breaths per minute for every degree Celsius above normal. Other causes include pneumonia, compensatory respiratory alkalosis as the body tries to “blow off” excess carbon dioxide, respiratory insufficiency, lesions in the respiratory control center of the brain, and salicylate poisoning. See also hyperpnea and hyperventilation.
transient tachypnea of the newborn a self-limited elevation of the respiratory rate in newborns due to delayed clearing of fetal lung water.

transient tachypnea of the newborn

Abbreviation: TTN
A self-limited condition often affecting newborns who have experienced intrauterine hypoxia resulting from aspiration of amniotic fluid, delayed clearance of fetal lung fluid, or both.

9%, or approximately 1 in 15, of all late preterm deliveries," they noted, adding that the "adjusted risk of oxygen use, transient tachypnea of the newborn, mechanical ventilation, respiratory distress syndrome, pneumonia or newborn sepsis, and admission to the NICU all were significantly decreased for neonates with soft or elective precursors delivered at 37, 38, 39, and 40 weeks of gestation compared with late preterm.
Chapter 28 deals with major pulmonary disorders in the neonate such as transient tachypnea of the newborn, pneumonia, meconium aspiration and apnea of prematurity while Chapter 29 covers congenital and surgical disorders that affect respiration.
For example, the local radiologist may read the chest radiograph as "consistent with transient tachypnea of the newborn.
3) In addition, infants born at 37 to 38 weeks' gestation have a significantly elevated risk of transient tachypnea of the newborn (TTN) and persistent pulmonary hypertension.
