What to Do During an Opioid Overdose: Naloxone and CPR Response Guide in Canada

Understanding Opioid Overdose and Emergency Response

An opioid overdose can slow or stop breathing, making it a life-threatening emergency. Knowing what to do if someone overdoses or how to respond when a person is not breathing normally due to drugs can help save a life.

In Winnipeg, Manitoba, and across Canada, opioid-related emergencies remain a public health concern. Quick action—calling 911, giving naloxone, and starting CPR if needed—can significantly improve survival.

First Aid & Workplace Relevance in Canada

Overdose emergencies can happen in public spaces, schools, workplaces, and homes across Winnipeg neighbourhoods like Downtown, North End, and St. Vital.

Training is important for:

• Students and educators
• Workplace staff and supervisors
• Security personnel
• Community members and families

Programs such as CPR training Winnipeg, first aid certification Manitoba, and naloxone training Canada are increasingly common and help people respond safely and confidently.

Real-Life Scenario: University Students Trained to Respond to Overdoses

At University of the Fraser Valley, students are being introduced to life-saving training focused on overdose response.

The program, supported by coordinator Michele Giordano, aims to equip students with practical skills, including recognizing overdose signs, administering naloxone, and performing CPR.

Students learn how opioids such as morphine, heroin, and fentanyl affect breathing—and how naloxone can temporarily reverse these effects.

The initiative reflects a growing awareness that community members, not just healthcare providers, may be first on scene during an overdose.

Signs and Symptoms of an Opioid Overdose

Common warning signs include:

• Slow, irregular, or stopped breathing
• Unresponsiveness or inability to wake
• Blue or gray lips and fingernails
• Pinpoint pupils
• Gurgling or choking sounds

These signs require immediate emergency action.

What Is Naloxone and Why Is It Used?

Naloxone is a medication designed to reverse the effects of opioids.

How It Works

• Naloxone blocks opioid receptors in the brain
• This can restore breathing in someone experiencing an overdose

Why It Is Used

• Opioids slow or stop breathing
• Naloxone helps counteract this effect temporarily

Effectiveness

• Naloxone is widely recognized as an effective emergency response tool
• It can work within minutes
• Multiple doses may sometimes be required

Naloxone is commonly included in first aid and emergency response training programs across Canada.

---

How Naloxone Is Given

Naloxone is designed for public use and is commonly available as:

• Nasal spray (sprayed into the nose)
• Pre-filled injection (administered into the thigh)

These formats are intended to be simple and accessible for bystanders with basic training.

---

First Aid Response: What to Do

Based on standard first aid training practices in Canada:

1. Call 911 immediately
2. Check responsiveness and breathing
3. Administer naloxone if available
4. Begin CPR if the person is not breathing normally
5. Stay with the person until help arrives

These steps are commonly taught in overdose response and CPR training.

Causes and Risk Factors

Overdose risk may increase with:

• Use of opioids such as fentanyl, heroin, or prescription medications
• Mixing substances
• Unknown drug strength
• Reduced tolerance

Awareness can help reduce risk and improve response.

---

Prevention and Workplace Considerations

In Winnipeg and across Manitoba, communities are taking steps to improve safety:

• Expanding access to naloxone kits
• Providing training in schools and workplaces
• Promoting awareness of overdose signs
• Encouraging community response readiness

Prepared individuals can help bridge the gap until emergency services arrive.
