What is a non-freezing cold injury?
Nonfreezing cold injury — NFCI is a general term that includes trench foot and its nautical equivalent immersion foot. NFCI involves injury to the soft tissues, nerves, and vasculature of distal extremities from prolonged exposure to wet, cold (but nonfreezing; generally 0 to 15°C or 32 to 59°F) conditions.
What is the difference between frostbite and non-freezing injury?
Differential Diagnosis of NFCI. Frostbite is caused by temperatures at least several degrees below freezing, especially by exposure to cold air. NFCI cannot occur without moisture, so NFCI does not occur at temperatures much below freezing.
What are the 4 types of cold injuries?
Cold-Related Injuries
2.1 Hypothermia.
2.2 Freezing Injuries of the Extremities. 2.2.1 Frostnip. 2.2.2 Mild/superficial frostbite. 2.2.3 Deep/severe frostbite.
2.3 Non-freezing Injuries of the Extremities. 2.3.1 Chilblain. 2.3.2 Immersion (Trench) Foot.
What temperature is a cold injury?
Hypothermia or systemic cold injury occurs when the core body temperature has decreased to 35 degrees C (95 degrees F) or less. The causes of hypothermia are either primary or secondary. Primary, or accidental, hypothermia occurs in healthy individuals inadequately clothed and exposed to severe cooling.
