1. APGAR skin color, heart rate, reflex irritability, tone, respiration.
Performed at 1 and 5 mins. Repeat apgar until score is >7.
-Validity is decreased in preterm newborns.
-Not to be used as indicator for resuscitation.
2. Respirator
y -Oxygenated blood is diverted away from pulmonary circulation in utero
Adaptatio and flows through the foramen ovale (between R atrium and L atrium)
n and ductus arteriosus (pulmonary artery to the superior vena cava), to
(Newborn
the fetal body.
Transition)
-Decrease in production of lung fluid occurs near the end of pregnancy
and when labor begins due to a catecholamine surge.
-Drop in pH stimulates fetal chemoreceptors to trigger respiratory center
to initiate respiration.
-Hormones secreted by the placenta inhibit breathing-> when the cord is
clamped, breathing begins.
-Mechanical compression during labor pushes approx. 1/3 of fluid out of
fetal lungs. When the chest is delivered, it is reexpanded causing
negative pressure and fluid is replaced with air.
3. TTN Transient tachypnea of the newborn.
Residual fluid in the lungs-> alteration in o2 exchange-> work of
breathing is increased.
-Mild self-limiting disorder, lasts 12-72 hrs
-Infant who do not experience labor are more likely to develop
4. RDS Respiratory distress syndrome of the newborn.
Most common lung disease in premature newborns.
-Increased risk with diabetes and C/S
-Caused by lack of adequate amount of surfactant
- By 34-36 wks there is enough surfactant to support respiration and
protect against development of RDS.
-Surfactant prevents alveolar collapse and helps lungs to expand
