Cards

Term
What chemical factors cause the initiation of respirations in a newborn?
Definition
  • decrease of PO2 and increase of PCO2 which stimulates the respiratory center in the medulla
  • *clamping of the cord is thought to drop levels of prostaglandin which inhibits respirations
Term
What mechanical factors initiate newborn respirations?
Definition
  • intrathoracic pressure is increased during compression of vaginal birth
  • negative pressure is released upon birth, resulting in distribution of air into the lungs
Term
What thermal factors initiate newborn breathing?
Definition
  • temperature change D/T extrauterine environment stimulates the receptors in the skin, stimulating the respiratory center of the medulla
Term
What sensory factors stimulate the newborn breathing?
Definition
  • touch, smell, sight can stimulate the respiratory center
Term
Normal Vital Signs of a Newborn
Definition
  • abdominal breathing, 30-60 RR/min, shallow and irregular with <20 sec pauses
  • 100-120 BPM
Term
Signs of Respiatory Distress in a Newborn
Definition
  • nasal flaring, severe chest retraction
  • grunting, groaning
  • seesaw respirations (tummy out, chest down and vice versa)
  • apnea 20> or longer, with too low or too high RR
Term
Transient Tachypnea of the Newborn
Definition
  • extra fluid in the lungs remains or is cleared too slowly; it is harder for the newborn to inhale oxygen
  • baby breathes harder and faster
Term
What are the four modes of heat loss in an infant?
Definition
  • Convection
  • Radiation
  • Evaporation
  • Conduction
Term
Convection
Definition
  • flow of heat from the body surface to the cool air
  • *nursery is kept at 24 degrees celcius (72.5 degrees F)
Term
Radiation
Definition
  • loss of heat from the body surface to a cooler solid surface within relative proximity
  • *avoid placing infants near windows, doors and drafts
Term
Conduction
Definition
  • loss of heat from the bodu surface to cooler surfaces in direct contact
  • *protective covers should be used when placing infants in cribs or on scales, etc.
Term
Evaporation
Definition
  • heat loss that occurs when a liquid is converted to a vapor
  • *dry infant directly after birth and after bathing; most significant cause of heat loss in newborns
