Questions and Answers (100% Correct
Answers)
Maintenance of thermal balance and
Answer: Neutral thermal environment (NTE)
BALANCE heat loss vs heat production:
Answer: minimal O2 consumption/minimal caloric expenditure occur, it is normal
for them to have lower O2 (60-95%) in first ten minutes
NRP =
Answer: neonatal resuscitation program
Need to be dried off and
Answer: warmed immediately, place on mother's chest so they gain heat, they're
going from a very warm environment to room temperature (98 to 72 degrees)
Positive pressure ventilation (PPV):
Answer: providing pressured ventilation to person on the other side, we do this with
babies if they aren't doing this alone (we add air into their lungs for them thus
creating positive pressure)
HOW do term newborns lose heat?
Answer: External body surface to environment: flexed position minimizes surface
area
Internal core to external body surface
WHY do they lose heat?
Answer: Large body surface in relation to mass
Less insulating, subcutaneous fat
4 Heat Loss mechanisms
Answer: • Evaporation: water loss
• Convection: when air is blown on baby
• Conduction: when they touch or are touched by anything colder than them

• Radiation: any indirect source
Plastic sides of beds are used to
Answer: keep air currents off the babies
What Happens for heat to be produced?
Answer: • Thermoreceptors are stimulated
• Vasoconstriction and increased activity cannot compensate d/t high surface area to
volume ratio
• Non-shivering thermogenesis initiated
• Brown fat is metabolized to keep the body temperature stable, brown fat ~5% of
their body fat
THREE EVENTS initiate respirations:
Answer: Air replaces Fluid
Onset of Breathing
Increase in Pulmonary Blood Flow
Babies are going from a _____ environment to an _______ environment
Answer: fluid-filled, air-filled
Airway
Answer: • Process of Labor: Sodium transport system begins and pulls fluid from
lungs
• Initial inflation of lungs
o Mechanical Stimulation
o First Breath/Gasp: Surfactant needed for alveolar stability/to keep them open
Babies born via c-section have more fluid in their lungs than babies born vaginally
d/t
Answer: not having as much chest compression and thus less air filing lungs
