Exam 3 part 5 Flashcards
from birth to first 28 days of life
neonatal period
physiological adaptation to extrauterine life after delivery and the umbilical cord is clamped
Transition
lack of fetal breathing like movements are reported to cause
pulmonary hypoplasia
what happens to chemical stimuli during cord clamping
increase CO2
Increase PaO2
Increase gas exchange and pulmonary blood flow
Decrease O2 and pH
Decrease in pulmonary vascular resistance
when is surfactant produced
last 4 weeks
normal RR for neonates
30 60 bpm
is progressive respiratory distress during transition
transient tachypnea
Protects lungs against circulatory overload
Allows the right ventricle to strengthen
High pulmonary vascular resistance, low pulmonary blood flow
Carries mostly medium oxygen saturated blood
Ductus arteriosus shunt
Fetal blood vessel connecting the umbilical vein to the IVC
Blood flow regulated via sphincter
Carries mostly high oxygenated blood
Ductus venosus shunt
Shunts highly oxygenated blood from right atrium to left atrium
foramen ovale
how much more oxygen does fetal hemoglobin carry
30%
highest concentration of circulating O2 goes to
fetal brain and heart
neonate Hgb level
14-20 g/dl
neonate Hct level
43-55
neonate WBC level
10,000-30,000
neonate platelet count
150,000-350,000
air currents moving around baby
convection
Heat radiates to cooler surfaces (walls, surrounding air) and objects not indirect contact with body
radiation
loss due to water vapor conversion
evaporation
loss though direct contact with skin and cold surfaces
conduction
burn off glucose in order to stay warm because baby can not shiver
Thermogenesis
how bilirubin does neonates produce
8.5-10 mg/kg/day
