[First aid in excessive heat loss]

Area of Science:

• Physiology
• Environmental Medicine
• Emergency Medicine

Background:

• Heat loss is a significant physiological challenge, particularly in aquatic environments.
• Understanding the mechanisms of heat loss is crucial for preventing and treating hypothermia.
• Specific populations like swimmers, sailors, surfers, and divers face unique risks.

Purpose of the Study:

• To examine the physiopathological changes during heat loss and therapeutic warming.
• To analyze the first aid treatment for mild and severe heat loss.
• To differentiate immediate first aid from specialized therapeutic interventions.

Main Methods:

• Review of physiopathological changes associated with hypothermia.
• Analysis of heat loss mechanisms in various water-related activities.
• Evaluation of current first aid protocols for heat loss.

Main Results:

• Excessive heat loss in water is more common than often perceived.
• Mechanisms include cutaneous transpiration, respiration, heat dispersion, and environmental exposure.
• Populations at risk include swimmers, sailors, surfers, and divers.

Conclusions:

• First aid for heat loss must prioritize maintaining cardiorespiratory functions.
• Therapeutic warming requires specialized treatment centers and equipment.
• Prompt and appropriate first aid can mitigate severe outcomes of hypothermia.
