Hypothermia
DDx
Exposure
Infection
Mild 32-35C
Moderate 28-32C
Severe <28C
Heat convection = conduction of heat from body to air/water and advection (transport away by that fluid)
More effective in water than air
Temperature of water/air defines the amount of time it will take to overcome the body's thermogenic mechanisms
Higher water/air flow quickens this effect
Shivering and non shivering thermogenesis
vasoconstriction
Active movements
Children in general have more BSA and less fat and reduced thermogenesis
Pathophysiology: reduces cognition, coordination, and muscle strength > ineffective breathing + reduced cardiac output > cardiac arrest
