Q
Factors initiating breathing after birth:
A
-reflex triggered by such factors as pressure changes, chilling, noise, light, and other sensations associated with exposure to extrauterine life and chemoreceptor activation by lowered oxygen level, higher carbon dioxide level, and lower pH
24
Q
Conditions essential for maintaining an adequate oxygen supply:
A
-removal of lung fluid, synchronous expansion of chest and abdomen, patent airway, and sufficient surfactant
25
Expected newborn respiratory pattern:
-shallow and irregular rate of 30 to 60 breaths/min, short periods of apnea less than 20 seconds, and loud and clear breath sounds
26
Signs of respiratory distress:
- nasal flaring, retractions, and increased use of intercostal muscles
- grunting with respirations
- seesaw respirations
- rate of less than 30 or more than 60 breaths/min at rest
- apnea longer than 20 seconds
- adventitious breath sounds
27
Foramen ovale: purpose/location--closure mechansim:
- formation of a valve opening that allows blood to flow directly to left atrium (shunting of blood from right to left atrium)
- functionally closed at birth, constant apposition gradually leading to fusion and permanent closure within a few months or years in majority of persons
- increased pressure in left atrium and decreased pressure in right atrium causing closure of valve over foramen
28
Ductus arteriosus: purpose/location--closure mechanism:
- patent, shunting of blooding from pulmonary artery to descending aorta
- functionally closed almost immediately after birth, anatomic obliteration of lumen by fibrous proliferation requiring 1-3 mo, becoming ligmentum arteriosum
- increased oxygen content of blood in ductus arteriosus creating vasospasm of its muscular wall
- high systemic resistance increasing aortic pressue; low pulmonary resistance reducing pulmonary arterial pressure
29
Ductus venosus: purpose/location--closure mechanism:
- closed, becoming ligamentum venosum after obliteration
| - loss of blood flow from umbilical vein
30
Dangers of stress cold for a newborn:
- metabolic and physiologic demands on the newborn increase, leading to increased oxygen need and consumption
- oxygen and energy are diverted from brain cells, cardiac function, and growth
- decreased oxygen leads to vasoconstriction, respiratory distress, and reopening of the ductus arteriosus
- acidosis, increased level of bilirubin, hypoglycemia
31
Newborn behaviors associated with cold stress:
- increased respiratory rate
- cyanosis
- decrease in oxygen level, pH, and glucose level
- signs of acidosis
32
Measures to stabilize newborn temperature:
- implement measures that reflect application of heat loss mechanisms of convection, radiation, evaporation, and conduction
- dry infant and cover with warmed blankets or wrap with mother on her abdomen
- cover head
- use radiant heat shield or warmer to stabilize temperature initially
- assess newborn and perform procedures
- adjust environment
33
Convection--definition of heat loss/how to prevent:
- the flow of heat from the body surface to cooler ambient air
- ambient temperature is the nursery is kept at approximately 24* C, and newbornsin open bassinets are wrapped to protect them from the cold
34
Radiation--definition of heat loss/how to prevent:
- the loss of heat from the body surface to a cooler solid surface not in direct contact but in relative proximity
- to prevent this type of loss, nursery cribs and examining tables are placed away from outside windows, and care is taken to avoid direct air drafts
35
Evaporation--definition of heat loss/how to prevent:
- the loss of heat that occurs when a liquid is converted to a vapor
- dry infant completely after bath
36
Conduction--definition of heat loss/how to prevent:
- loss of heat from the body surface to cooler surfaces in direct contact
- place newborn in warm crib, scales used for weighing the newborn should have a protective cover
37
Characteristics of physiologic jaundice:
- manifestation of the pigment bilirubin in the tissues of the body
- appearance of jaundice after the first 24 hours of life
- should last less than 7 to 10 days
- appears when bilirubin level reaches 5 mg/dL
38

43
First period of transitioning to extrauterine life:
- lasts up to 30 mins after birth
- newborn's heart rate increases rapidly to 160 to 180 beats/min but gradually falls after 30 mins or so to a baseline rate of between 100 and 120 beats/min

- infant is alert
- bowel sounds are audible
- meconium may be passed
44
Second period of transitioning to extrauterine life:
- occurs roughly between 4 and 8 hours after birth and lasts from 10 mins to several hours
- brief periods of tachycardia and tachypnea occur, associated with muscle tone, skin color, and mucous production
- meconium is commonly passed
- most experience this transition regardless of gestational age or type of birth
45
