C
Terms in this set (179)
What are the 3 stages of the newborn transition period 1. First period of reactivity
2. Period of decreased responsiveness
3. Second period of reactivity
Define neonate First 28 days of life
How does the newborn present during the first period of Very alert, spontaneous tremors, crying
reactivity
Bowel sounds are audible
How long does the first period of reactivity last Up to 30 minutes long
How does the newborn present during the period of Heart rate may fall to baseline
decreased responsiveness Sleeping
Decreased motor activity
How long does the period of decreased responsiveness Lasts about 1- 1.5 hours
last
What event most likely occurs during the second period Meconium is most likely to be passed during this period
of reactivity
How does the fetus breathe, while in utero The placenta delivers oxygen, NOT the lungs
Fetus's cannot breathe with their lungs- why is this? While in utero, the lungs are fluid filled. They continually produce fluid, filling up
all the air spaces
At what week does this occur: 11 weeks
Fetus practice breathing movements essential for
developing chest wall muscles and diaphragm
Fetal blood is shunted away from lungs because they
aren't formed yet
At what week does this occur: 13-16 weeks
Some fluid moves into the trachea and into the amniotic
fluid and is swallowed
They practice swallowing movements
, At what week does this occur: 29-32 weeks
Rhythmic breathing movements occur
Fetal lung fluid decreases as labour approaches
A release of _____ before labour, tells the lungs to catecholamines
release fluid
If a fetus is exposed to catecholamines too early, before it can cause fetal absorption of fluid
labour, what can it cause?
Define surfactant A protein complex secreted by cells in lungs to keep lungs from collapsing by
decreasing the surface tension in alveoli.
Provide the lungs with stability, needed for gas exchange
What adventitious lung sound can be heard right after Audible crackles can be heard right after birth
birth
How to determine fetal lung maturity after the 35th week via amniocentesis
How do chemoreceptors induce respirations in the fetus Chemoreceptors in aorta and carotid, fetus is in a relative state of hypoxia →
causes chemical activation to induce respirations
How does the action of passing through the birth canal when baby is being born vaginally, changes occur as the fetus' chest is
induce respirations? compressed → air is forced in
How does a decrease in temperature induce newborn Decrease in temperature after birth causes receptors in skin to stimulate medulla
breathing to start breathing
Why do sensory actions, such as touching a newborn, Touching/ drying the infant/ lights/ sounds/ smells, can all trigger respirations
induce respirations
Lung expansion and first breaths must be strong enough an equal volume of air
to move fluids that fill the fetal airway from the trachea to
the terminal air sacs. The lung liquid must be replaced
with ______
What must be established, in order for the newborn to Functional residual capacity (i.e., air remaining in the lungs at the end of
successfully clear their airways expiration), must be established
Newborn respiratory rate? 30-60 bpm
shallow and irregular
When would periods of apnea be a concern (in a When it lasts more than 20 seconds, cyanosis and HR changes
newborn)
Periods of apnea, btwn ___ to ___ seconds can be 5-15 seconds
observed in the first few days of life. This is normal.
