Week 2 Flashcards
discharge begins when
admission
neonatal peroid
birth to 28 days
first peroud of reactivity
30 mins: HR increases to 160-180 and infant is alert
60-100 min: peroid of decreased responsiveness, infant is tired
second peroid of reactivity
2-8 hours after birth
10 min to several hours
tachycardia and pnea, increased muscle tone, improved skin color, meconium passed
what is responsible for gas exhange
placenta
ductus arteriosus
pulmonary artery to aorta
foramen ovale
door between atrial
ductus venosus
bypasses the liver
fetal Po2
20-30 mmHg
ducuts arteriousus and venous are converted to what in 2-3 months
ligaments
3 vessels in cord
AVA
what is oxygenated in the cord
vein
few first breaths do what to fetal lung fluid
air moves in and pushes the fluid in the lungs out
what happens in the atriums after delivery
pressure in left atrium increases and closes the door
most critical physiologic change
initiation of breathing
labor induces what changes in Co2, O2, and pH and what does that stimulate
mild hypercapnia
hypoxia
acidosis
stimulate the respiratory center
4 stimuli
chemical
mechanical
thermal
sensory
chemical stimuli
flow through umbilical and CO2 and pH and O2
mechanical stimuli
squeezed through pelvis
thermal stimuli
warm to cold
sensory stimuli
handling, talking, rubbing
what system is the last to develop
respiratory
fetal lungs secrete how much of fetal lung fluid
25-30ml/kg
fetal lung fluid helps develop what
alveoli
at term infants should hold how much of air
20mL
surfactant relating to age
increased surfactant with increased gestational age
why might C section have wetter lungs
because the decrease the squeezing
what to do if infant is not breathing
positive pressure ventilation
heart rate sleeping and awake
sleep 80-100
awake 120 to 160
BP (map)
equals weeks
40 MAP = 40 weeks
delayed cord clamping pros and cons
increase BV and BP
decrease risk of necrotizing enterocolitis and intraventicular hemorrhage
increase risk of jaundice
ductus arteriousus closes
24 hours
RBC
higher since the PO2 is lower the fetus needs additional RBC for oxygen transport
what is the best thing for a cold baby
skin to skin
4 heat loss modes
convection
radiation
evaporation
conduction
convection
air/draft
radiation
solid objects not touching
evaporation
fluid to aircon
conduction
2 objects touching
what is non shivering thermogenesis
brown fat metabolism
brown fat amount related to gesation
increase with gesation
what does the baby need for brown fat metabolism
O2 and glucose
