- Ductus Arteriosus - Connects the pulmonary artery and the descending aorta
How does chest compression in the narrow birth canal support the first breath?
- Helps force fluid out of the lungs into the upper air passages during birth.

How do thermal factors support respiration of a newborn at birth?
Lecture
The temperature change that occurs with birth also stimulates the initiation of respirations.
How do the sensory factors help stimulate the first breaths ?
Lecture
The stimulation of the light, sound, smell, and pain at delivery may also aid in initiating respirations.
What role do Chemical factors play in initial respirations of a newborn?
Lecture
Chemoreceptors in the carotid arteries and the aorta respond to changes in blood chemistry caused by the hypoxia that occurs with normal birth. A decrease in the partial pressure of oxygen (Po2) and pH and an increase in the partial pressure of carbon dioxide (Pco2) in the blood cause impulses from these receptors to stimulate the respiratory center in the medulla.
