What to Do in Cold Water Emergencies: Drowning, Hypothermia & CPR (Canada)

Understanding Cold Water Drowning and CPR

Cold water incidents are especially dangerous. Knowing what to do if someone is pulled from icy water and not breathing or how to respond when hypothermia is involved is critical.

A unique and important concept in cold water emergencies is that cold temperatures can slow the body’s metabolism, which may sometimes extend the window for resuscitation efforts.

Scenario: Drowning in Ice-Covered Lake in Nova Scotia

A tragic incident occurred at Indian Harbour Lake in Guysborough County, Nova Scotia, involving a 57-year-old woman.

• Two individuals went to check on her
• They discovered her in an ice-covered lake
• She was pulled from the water

They immediately:

• Began CPR
• Called emergency services

Despite their efforts, she was later declared deceased at hospital.

Investigators believe she may have entered the water while attempting to rescue a dog, though this was not confirmed.

This situation highlights the dangers of ice-covered water, which is also a concern across Manitoba during winter months.

A Unique CPR Insight: Cold Water and “Extended Rescue Window”

In cold water incidents:

• The body cools rapidly
• Oxygen demand may decrease
• This can sometimes allow longer resuscitation attempts compared to typical cases

Why This Matters

• CPR may still be effective even after longer submersion times
• Continuous efforts are important
• Early rescue and CPR remain critical

This concept is often summarized in training as:

“They are not considered beyond help until warming and assessment are complete.”

This principle is commonly discussed in advanced first aid and CPR courses in Canada.

First Aid Response: What to Do

Based on standard first aid training practices in Canada:

Step 1: Ensure Scene Safety

• Avoid stepping onto unsafe ice

Step 2: Remove the Person Safely

• Use reaching or throwing methods if possible

Step 3: Check Airway and Breathing

• If not breathing → begin CPR immediately

Step 4: Call Emergency Services

Step 5: Protect from Cold

• Remove wet clothing if possible
• Cover with dry materials

Step 6: Continue CPR

• Maintain steady compressions and breaths

Another Unique Factor: Cold Water Rescuer Risk

Many incidents occur when people attempt rescues:

• Ice may not support weight
• Cold shock can affect rescuers
• Secondary victims are common

Key takeaway:
Always prioritize your own safety first

Prevention and Water Safety Considerations

To reduce risks in Winnipeg and across Manitoba:

• Avoid walking on uncertain ice
• Supervise pets near frozen water
