    Area of Science:

    • Environmental Medicine
    • Physiology

    Background:

    • Hypothermia is a critical medical condition defined by a dangerously low core body temperature.
    • Understanding thermoregulation, fluid balance, and symptomless cooling is crucial for managing hypothermia.

    Purpose of the Study:

    • To provide a comprehensive overview of hypothermia, including its definition, classification, and physiological basis.
    • To detail the signs, symptoms, and diagnostic challenges associated with hypothermia.
    • To review and recommend practical treatment and rewarming strategies for hypothermia, especially in field settings.

    Main Methods:

    • Literature review and synthesis of existing knowledge on hypothermia.
    • Analysis of physiological responses to cold exposure.
    • Evaluation of diagnostic criteria and treatment protocols for hypothermia.

    Main Results:

    • Detailed classification and physiological summary of hypothermia.
    • Identification of diagnostic challenges, including differentiating hypothermia from death and considering complicating factors like drowning and the diving reflex.
    • Three practical rewarming methods identified for field use by rescue services.

    Conclusions:

    • Effective management of hypothermia requires careful diagnosis, consideration of complicating factors, and appropriate rewarming techniques.
    • Intensive care monitoring is essential for safe rewarming.
    • Alternative explanations for post-rescue mortality in hypothermia survivors are proposed, and caution advised when interpreting research.
