30-60/min

3
Q

How long do you count a NB’s RR for?

A

60 seconds, may be irregular

4
Q

What are the “bypass vessels” in a NB?

A
  • ductus venosus
  • ductus arteriosus
  • foramen ovale
5
Q

How many arteries and veins are in the umbilical cord?

A

2 arteries, 1 vein

6
Q

Which vessels carry blood from the fetus to the placenta?

A

umbilical arteries carrying de-oxygenated blood

7
Q

Which vessels carry blood from the placenta to the fetus?

A

umbilical veins carrying oxygenated blood

8
Q

Which vessel bypassed the liver and takes blood into the inferior vena cava in a fetus?

A

ductus venosus

9
Q

Which vessel shunts blood from the pulmonary artery to the aorta in a fetus?

A

ductus arteriosus

10
Q

Which vessel shunts blood from the right atrium to the left atrium in a fetus?

A

foramen ovale

11
Q

Describe the process for closing the foramen ovale after birth?

A
  • air fills the alveoli, expanding them and decreasing resistance and pressure in lungs
  • blood from the right side of heart can now go to the lungs, decreasing the pressure in the right atrium and increasing the pressure in the left atrium.
12
Q

What happens in response to the release of bradykinin from the lungs after expansion in a NB?

A

causes constriction of the ductus arteriosus after mixing with O2 in the blood

13
Q

How is the ductus venosus closed in a NB after birth?

A

clamping of the umbilical cord stops blood flow through the ductus arteriosus causing its constriction

14
Q

How long after birth does is take for the ductus venosus close permanently?

A

1 week

15
Q

The ductus venosus becomes what vessel after its closure?

A

ligamentum venosum

20
Q

What is acrocyanosis?

A

bluish coloration of the hands and feet, disappears with cry

21
Q

Infant response to hypothermia (cold stress)?

A
  • increase O2 consumption and RR
  • vasoconstriction
  • increase anaerobic glycolysis = metabolic acidosis
22
Q

Infant response to hyperthermia?

A

vasodilation, some perspiration, increase o2 consumption and increase BMR

23
