What does the ideal implementation of Kangaroo Care involve?
- A warm, quiet environment
- Infant upright on parent chest, ear over heart, skin to skin
- Encourage to rock/ stroke infant
- Decrease activity if overstimulated
What are the benefits of Kangaroo Care?
- increased sleep time
- HR regularity
- Fewer apneic and bradycardic spells
- decreased O2 levels
What are the outcomes/ benefits of Kangaroo care?
- thermal synchrony
- effective breastfeeding
- more rapid weight gain

Explain the pathophysiology of Transient Tachypnea of the Newborn (TTN)
TTN occurs when the liquid in the lungs is removed incompletely or slowly during delivery and shortly after
(Fetal lungs filled with fluid –> and the fluid is removed and replaced with air during usual delivery)
What is the management of Transient Tachypnea of the Newborn (TTN)?
Oxygen or CPAP as needed
Supportive care
IV fluids or gavage feedings
(Normally not an emergency, so only supportive care needed, e.g., suction with bulb or deeper suction)
What are the risk factors for Transient Tachypnea of the Newborn?
Low gestational age
Cesarean birth
Precipitous delivery
Perinatal hypoxia
Male sex
