T. TACHYPNEA OF A NEWBORN
At birth, a newborn may have a rapid rate of respiration, up to 80 breathes / minute when crying
Within 1 hour, this rapid rate slows between 30-60 breaths / minute
The respiratory rate remains at a high level, between 80-120 breathes/ minute.
S/S
The infant does not appear to be in a great deal of distress, aside from the tiring effort of breathing so rapidly.
Has mild retractions but not marked cyanosis.
Mild hypoxia & hypercapnia
Feeding is difficult because the child cannot suck & breathe deeply at the same time.
Chest X-ray reveals some fluid in the central lung, but aeration is adequate.

Feeding is difficult because the child cannot suck & breathe deeply at the same time.
Chest X-ray reveals some fluid in the central lung, but aeration is adequate.
CAUSES
Result from slow absorption of lung fluid
Reflect a slight decrease in production of phosphatidyl glycerol or mature surfactant
These factors limit the amount of alveolar surface area available to the infant for gas exchange
Thus, the infant must increase the respiratory rate & depth to better use the surface available.
NURSING CARE
Close observation of the NB is the priority.
Watch carefully that increased effort in not tiring.
Watch for beginning signs of a more serious disorder because rapid RR is the first sign of respiratory obstruction.
Oxygen administration
Transient Tachypnea of the NB peaks at approximately 36 hours of life & slowly begins to fade at 72 hours as lung fluid is absorbed & respiratory activity becomes effective.
