Winter Weather & Cold-Related Medical Emergencies: What Nursing Students Should Watch For
As Edmonton enters deeper winter temperatures, cold-related emergencies become increasingly common. Whether you're a nursing student, frontline worker, or simply preparing for the season, recognizing the early signs of frostbite, hypothermia, and cold-induced cardiac arrest is essential.
Cold-Related Medical Emergencies
Cold injuries progress quickly, often without obvious warning. This is when strong Basic Life Support (BLS) skills can make a life-saving difference.
Recognizing Cold-Exposure Emergencies
Frostbite
Frostbite occurs when skin and underlying tissues freeze due to prolonged exposure to cold. Early recognition prevents long-term damage.
Early symptoms include:
Numbness or tingling
Pale, grey, or waxy-looking skin
Skin that feels firm or frozen
Loss of sensation in affected areas
Advanced frostbite may include:
Blisters after rewarming
Skin that becomes hard, blackened, or necrotic
Permanent nerve or tissue damage
Hypothermia
Hypothermia happens when the body temperature falls below 35°C. It is a true medical emergency.
Mild–Moderate hypothermia symptoms:
Persistent shivering
Lack of coordination
Slurred or slowed speech
Confusion or irritability
Severe hypothermia symptoms:
No shivering
Blue or cold skin
Decreased level of consciousness
Slow heart rate and breathing
Potential cardiac arrest
Severe hypothermia can mimic sleep or intoxication, causing dangerous delays in seeking medical help.
Why BLS Skills Matter More in Winter
Cold exposure affects breathing, heart rhythm, and brain function. A hypothermic person may suddenly collapse due to cold-induced dysrhythmias. Bystanders often assume the person simply “passed out,” but time is critical.
A trained BLS responder will:
Assess for responsiveness
Check breathing effectively
Call EMS immediately
Begin high-quality CPR when required
Use an AED correctly — even outdoors
Continue care until EMS arrives
In winter emergencies, early CPR and rapid defibrillation dramatically increase survival rates.
Home Treatment & Self-Care to Stay Safe This Winter
Avoid prolonged exposure to cold and wind
Wear moisture-wicking layers, gloves, thermal socks, and insulated footwear
Change wet clothing immediately
Carry blankets, warm packs, and emergency gear in your vehicle
Watch for cold stress signs in outdoor workers, children, and seniors
Avoid alcohol while outdoors — it increases heat loss
If someone becomes confused, extremely cold, or collapses: treat it as an emergency. Call 911 and begin BLS.
