Transition to Extrautine Life

Question 1

conduction heat loss

Answer 1

transfer of heat between solid objects of different temperatures in contact with each other - example: placing a neonate on cold scale vs a warmed scale or warmed blanket

Question 2

convection

Answer 2

transfer of heat through air currents moving around and across an infants body - example: neonates heat can be lost w a cool draft; incubators provide warm air to keep infant warm

Question 3

radiation

Answer 3

heat transferred between two objects not in contact with each other - emission of infrared rays - example: radiant warming beds

Question 4

evaporation

Answer 4

loss of heat occurs when moisture evaporates from the surface of the skin; example - drying the infant after birth and replacing wet linens with dry ones

Question 5

evaporated heat loss related to preterm infants

Answer 5

less then 31 weeks, skin is full developed, increased risk of fluid and heat loss. need humid environment, dry environments promote evaporation of heat and fluid loss via skin. incubators should have humidity controls and neonates kept in high humidity environments

Question 6

where is brown fat abundant?

Answer 6

around neck, midscapular region of back, and the mediastinum and organs in the thoracic cavity, kidneys and adrenals glands

Question 7

what is servocontrol?

Answer 7

the thermistor probe used to monitor the temperature of the infant in an incubator or radiant warmer
