75
Describe Apnea in a neonate
1. Apnea is often seen in premature newborns weighing less than 1,500 grams.
2. It may be accompanied by bradycardia, cyanosis, or both.
3. 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.
4. Obstructive apnea is the lack of airflow despite continuation of respiratory effort; chest movement continues but there is no airflow.
5. Mixed apnea is a combination of central and obstructive apnea, with the central component usually followed by obstruction.
76
Apnea vs. Periodic breathing
-Periodic breathing is characterized by intermittent respiratory pauses for up to 10 seconds is a frequent finding in premature infants.
77
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.
78
What factors increase insensible water loss?
- Use of a radiant Warmer. Phototherapy
79
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.
