Modes of heat loss
Loss of heat occurring when liquid converted to a vapor
What is evaporation?
Up to 30 minutes after birth
How long does the 1st stage of transition last?
This blood yields higher values than that blood
What is capillary and venous?
To be able to detect disorders in adaptation soon after birth
Why is it important to be aware of normal features of the neonatal transition period.
30-60
What is the spectacle respiration range?
Flow of heat from body surface to cooler ambient air
What is convection?
-NB quiet and begins to rest/sleep
-pink, respirations are rapid up to 60 and shallow but unlabored
-bowel sounds are audible and peristaltic waves may be noted over rounded belly
What is the period of decreased responsiveness?
39% to 59% at birth
What is the hematocrit range for a newborn?
The time from birth through day 28 of life.
What is the neonatal period?
Exaggerated rise in abdomen with respirations as the chest falls.
What are seesaw or paradoxic respiration?
Loss of Heat from body surface to cooler solid surface not in direct contact but in relative proximity
What is Radiation?
From 60 to 100 minutes
How long does the 2nd stage of transition last?
4.6 to 5.2 million/mm3 at birth
What is the RBC range for a newborn?
Used to identify infant's blood type and Rh status
What is cord blood sample?
Suprasternal or subclavicular retractions with stridor or gasping.
What are signs of upper airway obstruction?
Loss of heat from body surface to cooler surfaces in direct contact.
What is Conduction?
-NB awakens and becomes responsive
-Gag and chokes on mucus in mouth
-brief periods of tachycardia and tachycardia
-healthy newborns experience this transition regardless of gestation age or birth type
-preterm infants do not
What is the 2nd period of reactivity?
14 to 24 g/dl at birth
Decreases gradually to 12 to 20 during 1st two weeks
What is the hemoglobin range for newborns?
-regulating weight
-establishing and maintaining respiration
-adjusting to circulatory changes
-regulating temp
-ingesting, retaining and digesting nutrients
-eliminating waste
What are neonatal physiologic adjustment tasks?
Stimulates respirations/respiratory center.
What is the medulla?
-temp of humidity of the air
-flow and velocity of the air
-temp of surfaces in contact with and around the infant
What are factors that influence NB body temperature?
-NB alert, exhibits exploring activity, makes sucking sounds
-HR rapid to 160 to 180 but will stabilize
-fine crackles heard on auscultation
-audible grunting, nasal flaring and chest retraction can be present but should resolve within 1st hour after birth
What is the first period of reactivity?
Significant factor in levels of RBCs, Hgb, and Hct
What is the source of the blood sample?
-Establishing a regulated behavior temple independent of the mother.
- Processing, storing, and organizing multiple stimuli.
-Establishing a relationship with caregivers and the environment.
What are neonatal behavior tasks?
-Nasal flaring
-intercostal/subcostal retractions.
-Grunting.
-Tachypnea- up to 100 breaths per minute.
-circumoral cyanosis- bluish lips/mucous membranes
What are signs of respiratory distress?
