What does Fetal Asphyxia mean?
Without a Pulse
What causes Fetal Asphyxia?
Impaired maternal blood flow to the fetus (Placental Insufficiency)

What results in Fetal Asphyxia?

Hypoxia
Hypercarbia
Respiratory & Metabolic Acidosis

Primary Apnea

> Deprivation of Oxygen
Oxygen & Stimulation will induce respirations
Period of rapid breathing followed by apnea
HR begins to fall...

Secondary Apnea

> Unresponsive to stimulation
Deep irregular gasping
HR & BP Decrease
If continues, HR & RR cease, O2 falls, death occurs

Primary Apnea

> Deprivation of Oxygen
Oxygen & Stimulation will induce respirations
Period of rapid breathing followed by apnea
HR begins to fall
If apneic, baby will begin to breath when given oxygen and stimulated

Secondary Apnea

> Unresponsive to stimulation
Deep irregular gasping
HR & BP Decrease
If continues, HR & RR cease, O2 falls, death occurs
