Describe Apnea in a neonate
- Apnea is often seen in premature newborns weighing less than 1,500 grams.
- It may be accompanied by bradycardia, cyanosis, or both.
- Central apnea occurs when respiratory effort ceases; there is no chest movement and no airflow. It is significant when it exceeds 20 seconds; it is also significant when it is less than 20 seconds if it is associated with bradycardia or color change.
- Obstructive apnea is the lack of airflow despite continuation of respiratory effort; chest movement continues but there is no airflow.
- Mixed apnea is a combination of central and obstructive apnea, with the central component usually followed by obstruction.
Apnea vs. Periodic breathing
-Periodic breathing is characterized by intermittent respiratory pauses for up to 10 seconds is a frequent finding in premature infants.
Name the 4 Mechanisms for losing heat and an example of each.
- Conduction– transfer of heat from newborn to a cooler surface in direct contact – example: placing infant on a cold scale to obtain weight.
- Convection– loss of heat to cooler surrounding air, air current or draft – example: resuscitation bag blowing cold air is left in the incubator.
- Evaporation– loss of heat when liquid evaporated from skin – example: infant is not dried immediately after delivery
- Radiation- transfer of heat to a cooler object not touching the infant – example: infant is in a single walled incubator without a heat shield.

- Use of a radiant Warmer. Phototherapy
What is insensible water loss?
- The amount of fluid lost on a daily basis from the lungs, skin, and respiratory tract. Amount cannot be measured.
