PCC Role-based Guidance for Hypothermia Management
T T Role 1a
C C • Use a battery-powered warming device to deliver IV resuscitation fluids, in accordance with SECTION 1
C C current TCCC guidelines, at flow rate up to 150mL/min with a 38°C output temperature.
C C • Communicate re-supply requirements.
- - Role 1b
C C • Convert to continuous temperature monitoring.
M P » Minimum: Scheduled temperature measurement with vital sign evaluations.
C P » Better: Continuous forehead dot monitoring.
» Best: Continuous core temperature monitoring.
• Protect the casualty from exposure to wind and precipitation on any evacuation platform.
Role 1c
• Continue and/or initiate the Role 1a/Role 1b phases as detailed above.
• Replace ready-heat-blanket when using >10 hours.
• Interventions for both CMC and CPP are the same.

Hyperthermia
Background
1. Hyperpyrexia is elevated body temperature.
2. Fever is elevated body temperature in response to a change in hypothalamic set point
(infections).
3. Hyperthermia is elevated body temperature without a change in hypothalamic set point
(heat illness, hyperthyroid, drugs).
4. The Second Law of Thermodynamics states that heat flows from hot to cold.
5. Heat transfer can occur through several processes:
a. Radiation
b. Conduction
c. Convection
d. Evaporation
Heat exhaustion
Symptoms: weak, dizzy, nauseated, headache, sweating, normal mental status. Heat ex-
haustion requires replacement of fluids and electrolytes.
Heat stroke
Symptoms: Hyperthermia + mental status changes. Heat stroke requires immediate cooling.
