Mechanism of heat loss in neonates
Hypothermia –> Norepi release –>
activate non-shivering thermogenesis by metabolism of brown fat
> Inc muscle activity and metabolism –> O2 consumption –> hypoxemia
> Pulmonary vasoconstriction –> hypoxia
> Increase glucose utilization –> hypoglycemia

Conduction
Radiation
Convection
Evaporation
