The flashcards below were created by user NurseFaith on FreezingBlue Flashcards.

  1. Continuously monitor ____ and ____ in the neonate
    Temperature and Glucose
  2. Alveoli are developed by the ____ week gestation and adequate surfactant by the ___ week
    25th and 35th
  3. What keeps the fetus from taking real breath before birth:
    Inhibitory mechanisms:

    • Physical stimuli
    • (compression on babies chest clears fluid)

    • Thermal stimuli
    • (temperature going from warm to cooler)

    • Chemical stimuli
    • (pH regulator...imbalance from when bloodflow wasn't being given to baby during contractions)

    • Tactile Stimuli
    • (dry baby vigorously)
  4. C-Section babies will have more -___ issues because they don't have the compression on their lungs during labor
  5. Types of inhibitory mechanisms
    Facial immersion

    Inhibition by presence of fluid in the laryngeal area
  6. Types of physical stimuli that initiate respiration
    passing the birth canal and compression on the thorax (excretion of up to 30 ml of tracheal fluid )

    Some fluid remains in small airways to decrease the pressures needed to establish lung expansion than if the area was fluid free (air-fluid interface)

    First breath creates negative intrathoracic pressure and some of the air then remains as residual (less pressure to reinflate subsequently)
  7. Types of thermal stimuli initiating respirations:
    Cold stimulation induces breathing (exit from uterus stimulates impulses to stimulate respiratory center)
  8. Chemical stimuli initiating respirations
    Chemoreceptor in the carotid artery are stimulated to initiate respirations....stimulated by:

    • Decreased ox (80-15)
    • Increased CO2 (40- 70)
    • Decreased pH (below 7.35)

    Delayed respirations (increased CO2, decreased pH, and increased resp depression)
  9. Types of Tactile stimuli initiating respirations:
    Normal handling in the delivery room

    ***If newborn respirations are depressed, time should not be spend on using tactile effects to stimulate respirations
  10. Lipoprotein produced by alveolar epithelium (first detected at 28 weeks)...acts to decrease surface tension therefore alveoli remains open
  11. Surface tension is ____ proportional to the size of the alveoli...

    (Small alveoli increase the effect of surfactant. This is a significant property since the size of alveoli decrease during expiration)
  12. Fluid remaining in the baby's lungs is absorbed by:
    alveolar capillaries and lymphatics
  13. Neonatal breathing is ___ due to the horizontal rib position

  32. Cardio Adaptations of Foramen Ovale
