Q

Respiration

A

-Most critical and immediate physiologic change
-Fetal lung fluid removal: compression of chest w/ passage thru birth canal, lymphatic vessels and pulmonary capillaries
-Expansion of alveoli: occurs w/ initiation of breathing, role of surfactant in keeping alveoli expanded

Q

Circulation

A

-Foramen ovale circulatory changes allow blood to flow thru lungs
-Pressure changes in heart, lungs, vessels
-Functional closure of fetal shunts d/t increased oxygenation of blood: ductus arteriosus and venosus

Q

Sequential circulatory changes

A

-Inspired O2 dilates pulmonary vessels

Q

Further circulatory changes

A

-LA pressure greater than RA pressure leads to closure of foramen ovale
-Increase of pulmonary blood flow and dramatic reduction of pulmonary vascular resistance begins to close the ductus arteriosus

Q

Typical times for circulatory chnages

A

-Foramen ovale: close soon after birth

Q

Thermoregulation

A

-Critical to survival
-Principal thermogenic sources: heart, liver, brain, brown adipose tissues (BATs)
-Babies born w/ lots of brown fat behind shoulder blades, newborns can’t shiver so brown fat acts as built-in heater

Q

Factor predisposing newborn to excessive heat loss

A

-Large surface area results in heat loss

-Neuromuscular disorders

22
Q

Transitional assessment

A

24
Q

Cry assessment

A

-Strong, lusty cry at birth
-5 min - 2 hr or more per day

-Absent, weak, or constant crying may suggest pathology
-High-pitched, shrill cry indicates increased ICP
-Crying status alone is not a dx tool
