Question 4

what happens to chemical stimuli during cord clamping

Answer 4

increase CO2
Increase PaO2
Increase gas exchange and pulmonary blood flow
Decrease O2 and pH
Decrease in pulmonary vascular resistance

normal RR for neonates

Answer 6

30 60 bpm

Question 7

is progressive respiratory distress during transition

Answer 7

transient tachypnea

Question 8

Protects lungs against circulatory overload
Allows the right ventricle to strengthen
