NUR 206 U3M4
Newborn respiration
Physiology:
-Lung fluid absorbed at birth, surfactant prevents lung collapse
-As infant cries, lung pressure increases, causing remaining lung fluid to be
absorbed


Nursing Implications:
-Bulb suctioning at birth
-Assess respiration rate and sound
-Have ambu-bag if needed at birth




Newborn cardiovascular changes
Physiology
-At birth, shunts close and pulmonary vessels dilate
-Pressure increases within left atrium (higher than right) so foramen ovale
closes and ductus arteriosus closes
-This allows blood flow to go to lungs to be oxygenated


Nursing interventions
-Assess for cyanosis and hypoxia
-Listen to heart rate, and lung sounds




Newborn Thermoregulation

, Physiology:
-Thin skin, decreased white and brown fat, increased surface area, and non
flexed posture increase heat loss=


Nursing Implications:
-Dry baby immediately, put in blankie/hat
-Kangaroo care, heat lamps




Newborn cold stress
Physiology:
-Increased metabolism of brown fat leads to increased oxygen and glucose
need


Nursing Implications:
-Keep infant in neutral thermal environment
-Hat on head to prevent heat loss, blankies




Transitory deficiency in newborn blood coagulation
Physiology:
-Low Vit K, which is necessary to activate several clotting factors
-Vit K made in intestines, but newborns need normal food and flora to make
this so it takes a while
-Mom taking meds such as phenytoin, phenobarbital, and anti-TB meds can
reduce clotting ability
