When faced with a medical emergency, having a solid understanding of basic first aid techniques can be the difference between life and death. Whether at home, work, or in public spaces, possessing fundamental first aid skills can empower you to respond effectively and decisively. In this blog, we'll explore five common life-saving first aid techniques that everyone should know.
Cardiopulmonary Resuscitation (CPR):
Cardiopulmonary Resuscitation, or CPR, is a critical skill used to revive individuals experiencing cardiac arrest. By combining chest compressions and rescue breaths, you can maintain blood flow and oxygenation to vital organs until professional medical help arrives. CPR training is widely accessible, and mastering this technique can significantly increase the chances of survival in emergencies.
Back Blows and Abdominal Thrusts:
Choking is a prevalent emergency that can happen anywhere, and knowing how to respond is crucial. The combination of back blows and abdominal thrusts is a technique used to dislodge a foreign object obstructing the airway. Begin with five sharp back blows between the shoulder blades, followed by five abdominal thrusts to force air from the lungs and expel the obstruction. This method can be a lifesaver in situations where swift action is necessary.
Stop the Bleed:
Uncontrolled bleeding is a leading cause of preventable death in emergencies. The "Stop the Bleed" technique focuses on controlling external bleeding until professional medical assistance arrives. Applying direct pressure to the wound with sterile bandages or clothing, using tourniquets when necessary, and elevating the injured limb are essential components of this life-saving skill.
Recovery Position:
The recovery position is a simple yet vital technique used to maintain an open airway for an unconscious person who is breathing. Placing the individual on their side helps prevent choking on vomit or other fluids and promotes proper breathing. This technique is particularly useful in cases of alcohol or drug overdose, where maintaining a clear airway is critical until medical help arrives.
AED (Automated External Defibrillator) Use:
AEDs are portable devices that deliver an electric shock to restore the heart's normal rhythm in cases of sudden cardiac arrest. Learning how to use an AED, in conjunction with CPR, can significantly increase the chances of survival for someone experiencing a cardiac emergency. Many public places and workplaces are equipped with AEDs, making understanding their proper use invaluable in time-sensitive situations.

Your quick response and expertise could be the key to saving lives.
AEDs: The Basics
Sudden cardiac arrest (SCA) is a leading cause of death worldwide, with millions of people experiencing it each year. AEDs, or Automated External Defibrillators, are critical in treating SCA because they can deliver a life-saving shock within minutes of the onset of symptoms. This blog post will cover the basics of AEDs, including how they work, why they're important, and how to use them.
Automated External Defibrillators (AED): What You Need to Know
An Automated External Defibrillator, or AED, is a portable electronic device used to treat sudden cardiac arrest (SCA) in conjunction with Cardiopulmonary Resuscitation (CPR). AEDs are designed to be used by anyone, regardless of their level of training or experience, to help save lives in emergency situations.
A person wearing gloves is performing first aid on a CPR dummy, while following AED directions. The person's hands are on the chest of the dummy, as if performing chest compressions. There is an AED device next to the dummy, with the pads attached to the dummy's chest.
How Does An AED Work?
AEDs work by analyzing the heart rhythm of a person experiencing SCA, and then delivering an electric shock to restore the heart's natural rhythm. The device comes with two sticky pads with attached wires, called electrodes. These pads are placed on the person's chest, and the AED's computer analyzes the heart rhythm through the electrodes. If the AED determines that the person's heart is in ventricular fibrillation or another treatable rhythm, it will prompt the user to deliver a shock. However, if the person's heart is in asystole, which is the absence of any heart rhythm, the AED will not deliver a shock. It's important to note that the use of an AED on a person with no heart rhythm (asystole) is not recommended because it is unlikely to be effective.
AED + CPR
CPR, or cardiopulmonary resuscitation, is a life-saving technique used to help someone who is in cardiac arrest. It involves a combination of chest compressions and rescue breaths to manually circulate oxygen-rich blood through the body when the heart is not beating effectively. CPR is performed when someone is unconscious, not breathing, and has no pulse.
When someone experiences sudden cardiac arrest (SCA), CPR should be performed while waiting for an AED to arrive or be retrieved. The combination of CPR and AED can significantly increase the chances of survival.
Why Are AED’s Important
Sudden cardiac arrest (SCA) is a leading cause of death worldwide, with millions of people experiencing it each year. AEDs, or Automated External Defibrillators, are critical in treating SCA because they can deliver a life-saving shock within minutes of the onset of symptoms. AEDs are easy to use, portable, and equipped with clear instructions and voice prompts. They can be stored in public places, homes, and businesses to provide quick access in case of an emergency.
Where Can I Find An AED?
AEDs are becoming more common in public places, such as airports, shopping centers, and schools. Many workplaces are also beginning to invest in AEDs for their employees and customers. It's important to know where the nearest AED is located in case of an emergency. Look for AEDs in clearly marked cabinets, often mounted on the wall. Some AEDs come with an audible alarm or flashing light to make them easier to find in an emergency. If you are unsure where an AED is located, ask your employer or contact your local fire department or ambulance service for more information.
How Can You Use An AED?
AEDs are designed to be simple and easy to use. Most devices come with clear verbal instructions and visual prompts that guide the user through the steps of using the device. Here is a brief overview of how to place AED pads on adults and children:
For adults: Place one pad on the upper right side of the chest and the other pad on the lower left side of the chest, as shown in the diagram on the AED or in the instructions. It's important to make sure the pads are placed correctly and securely on the skin.
For children: Pediatric pads should be used for children under the age of eight or weighing less than 55 pounds. These pads have a lower energy setting to avoid harm to the child. Place one pad on the center of the child's chest and the other pad on the child's back, just below the shoulder blades.
It's important to note that AEDs should not be used on a wet surface or in water. The chest should be shaved and dried if necessary to ensure good contact with the electrode pads. Sweat and other moisture can interfere with the proper function of the device.
Automated External Defibrillators are an important tool in treating sudden cardiac arrest. These devices can be used by anyone, regardless of their level of training or experience, to help save lives in emergency situations.
Responding to Mass Casualty Incidents: A Guide for First Responders
Responding to Mass Casualty Incidents is a critical aspect of emergency preparedness and response. Whether it's a natural disaster, a terrorist attack, or an accident, the ability to quickly and effectively manage large numbers of injured victims can mean the difference between life and death. In such situations, emergency responders must work together to triage, treat, and transport the injured to medical facilities. They must also ensure that the scene is secure and that all necessary resources are available to address the needs of those affected.
Mass casualty incidents (MCIs) are situations where a large number of people are injured or killed at the same time. These incidents can be caused by natural disasters such as earthquakes, floods, or hurricanes, as well as by human-made events such as terrorist attacks or shootings. First responders play a crucial role in responding to these incidents and saving lives.

The responders are wearing protective gear and are working together to triage, treat, and transport the injured to medical facilities. The scene is chaotic, with debris and injured victims scattered around, highlighting the urgency and importance of effective mass casualty incident response.
Ensuring Safety: When responding to an MCI, the first priority for first responders is to ensure their own safety. They should always approach the scene with caution and be aware of potential hazards such as fires, explosions, or collapsing buildings. Once they have determined that it is safe to enter the area, they should quickly assess the situation and determine the number of casualties, the severity of injuries, and the resources needed to provide care.
Establishing Command: The first responders should then establish a command center to coordinate the response efforts. This center should be located in a safe area outside the immediate danger zone and should have clear communication channels with all response teams. The command center should also have access to emergency medical services (EMS) and transportation resources to move patients to hospitals or other care facilities.
Phases of Response: The response efforts should be organized into three main phases: triage, treatment, and transportation. During the triage phase, first responders should quickly assess each patient's condition and assign them to one of four categories: immediate (red), delayed (yellow), minimal (green), or expectant (black). Patients who are classified as immediate require immediate medical attention and should be transported to a hospital as soon as possible. Patients who are classified as delayed require medical attention but can wait for treatment. Patients who are classified as minimal require little or no medical attention, and patients who are classified as expectant are unlikely to survive even with treatment.
During the treatment phase, first responders should provide medical care to patients based on their triage category. Patients who are classified as immediate should receive the most urgent care, such as controlling bleeding, opening airways, or stabilizing fractures. Patients who are classified as delayed should receive medical attention as soon as possible, but their injuries are not life-threatening. Patients who are classified as minimal may receive basic first aid, such as bandages or pain relief. Patients who are classified as expectant should receive comfort care to minimize their suffering. During the treatment phase of a mass casualty incident, first responders should provide medical care to patients based on their triage category, which is determined during the triage phase. The triage categories are immediate (red), delayed (yellow), minimal (green), and expectant (black).
Patients who are classified as immediate require the most urgent care as their injuries are life-threatening and require immediate attention. First responders should prioritize stabilizing these patients by controlling any bleeding, opening their airways to ensure they can breathe properly, and stabilizing fractures or other injuries as quickly as possible. This may include the use of tourniquets, airway management devices, and splints.
Patients who are classified as delayed have injuries that are not immediately life-threatening but still require medical attention. First responders should provide medical care to these patients as soon as possible, but the urgency is not as high as it is for patients classified as immediate. For example, delayed patients may need pain relief, wound care, or treatment for broken bones.
Patients who are classified as minimal have injuries that are minor and may only require basic first aid, such as bandages or pain relief. These patients do not require immediate medical attention and can wait for treatment while more urgent cases are addressed.
Patients who are classified as expectant have injuries that are so severe that they are unlikely to survive even with medical treatment. First responders should provide comfort care to these patients to minimize their suffering, which may include pain relief, emotional support, and communication with family members or loved ones.
In summary, during the treatment phase, first responders should prioritize patients based on their triage category and provide the appropriate level of medical care to each patient. By following these guidelines, first responders can provide efficient and effective care to those in need during a mass casualty incident.
During the transportation phase, first responders should transport patients to hospitals or other care facilities based on their triage category. Patients who are classified as immediate should be transported first, followed by delayed patients. Minimal patients can be transported later or given transportation advice. Patients who are classified as expectant may not be transported, depending on the available resources and the patient's condition.
In conclusion, first responders play a critical role in responding to mass casualty incidents. They should always prioritize their own safety and quickly assess the situation to determine the resources needed to provide care. By following a structured approach that includes triage, treatment, and transportation, first responders can efficiently and effectively provide medical care to patients and save lives.

Saving Lives with Automated External Defibrillators (AEDs): What You Need to Know
The importance of Automated External Defibrillators (AEDs) in cardiac emergency response cannot be overstated. This photo depicts an AED, ready to deliver life-saving defibrillation during a critical moment of a cardiac emergency.
Cardiac arrest is a sudden and life-threatening condition that occurs when the heart suddenly stops beating effectively. Immediate intervention is critical to increase the chances of survival, and Automated External Defibrillators (AEDs) have emerged as a crucial tool in saving lives during cardiac emergencies. In this blog post, we will explore what AEDs are, how they work, and why they are essential in cardiac arrest management.
What are AEDs?
An Automated External Defibrillator (AED) is a portable electronic device that is used to diagnose and treat life-threatening cardiac arrhythmias, such as ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT). AEDs are designed to be used by non-medical professionals, including laypersons, and are commonly found in public places, workplaces, airports, schools, and other high-traffic areas.
How do AEDs work?
AEDs work by delivering an electric shock to the heart to restore its normal rhythm. When a person experiences cardiac arrest, the heart's electrical activity becomes chaotic, causing the heart to quiver or fibrillate instead of pumping blood effectively. AEDs are equipped with built-in sensors and computer algorithms that analyze the heart's electrical activity through adhesive pads (called electrodes) placed on the person's chest. If a shockable rhythm, such as Ventricular Fibrillation (VF) or Ventricular Tachycardia (VT), is detected, the AED will prompt the user to deliver a shock by pressing a button or automatically deliver the shock if it is a fully automated AED.
An Automated External Defibrillator (AED) is a portable electronic device that is used to diagnose and treat life-threatening cardiac arrhythmias, such as ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT).
The shock delivered by the AED is intended to stop the chaotic electrical activity in the heart and allow the heart to reset itself and resume a normal rhythm. AEDs are designed to be safe and effective, with automated features that guide the user through each step of the process, including providing voice prompts, visual instructions, and feedback on the quality of CPR (cardiopulmonary resuscitation) being performed.
Why are AEDs important?
AEDs play a crucial role in improving the chances of survival for individuals experiencing sudden cardiac arrest. According to the American Heart Association (AHA), the use of an AED, in combination with CPR, can significantly increase the survival rate of cardiac arrest victims. In fact, for every minute that passes without defibrillation, the chances of survival decrease by approximately 10%. Therefore, quick access to an AED and early defibrillation is critical to increasing the chances of survival.

They are designed to be used by anyone, regardless of their medical training or experience. They are user-friendly, with clear instructions and prompts that guide the user through the entire process. Many AEDs also have visual aids, such as diagrams or animations, to assist users in correct pad placement and usage. This makes AEDs accessible and empowers bystanders to take immediate action during a cardiac emergency, even before professional medical help arrives.
AEDs are also lightweight and portable, making them easy to transport and use in various settings. They are often designed with durable cases, built-in carrying handles, and sometimes even equipped with backpacks or wall-mounted cabinets for easy storage and accessibility. Many AEDs also perform regular self-checks and have indicators that show their readiness status, ensuring that they are always ready for use in an emergency.
In addition to their ease of use and portability, AEDs are cost-effective. The cost of AEDs has decreased over the years, making them more affordable and accessible for public use. Some AEDs also come with maintenance packages, including
Another important aspect of AEDs is the potential for widespread community impact. When AEDs are strategically placed in public locations, they can be easily accessed and used by bystanders in the critical minutes following a cardiac arrest. This can significantly shorten the time to defibrillation and increase the chances of survival. Many communities, workplaces, and public facilities have recognized the importance of having AEDs readily available and have implemented AED programs as part of their emergency response plans. These AED programs often include training initiatives to educate community members on how to recognize cardiac arrest, perform CPR, and use an AED effectively, further empowering the community to respond to cardiac emergencies.
In conclusion, Automated External Defibrillators (AEDs) are crucial tools in saving lives during cardiac emergencies. Their ease of use, portability, affordability, and potential for widespread community impact make them essential components of cardiac arrest management. By providing early defibrillation and increasing the chances of survival, AEDs empower bystanders to take action and make a significant difference in saving lives. If you encounter someone experiencing sudden cardiac arrest, remember to call emergency services, start CPR, and locate and use an AED as soon as possible for the best chance of survival.
Don't Train on Trash
Flimsy cardboard and pillows? Why would you train CPR on the most unrealistic devices available? Find out what you’re missing by training on trash.
In the early 2000’s I worked in the Alberta oilfield. I had to constantly update my first aid and CPR certification, H2S, WHIMIS, TDG, Confined Space, Fall Protection, etc. Recertifying in first aid and CPR was always a dreaded day; or weekend! It was hard to stay awake, and sometimes the instructor’s voice was a monotonous drone. Often the equipment was old, and it always felt unrealistic. During the CPR portion of class, I felt CPR on an actual person had to feel different than a performing it on flimsy cardboard and a pillow.
Garbage
These are types of popular CPR mannequins used in many first aid courses. If you’ve taken a first aid/CPR course with these in the past, you might as well practice CPR on a pillow.
Does it really matter?
Most people taking a first aid and CPR course are doing it for job requirements. Either for your current job, or a new career that requires first aid training. While at work, the chances of you utilizing your first aid training on a co-worker is much higher than performing CPR on them.
You can practice a leg splint or an arm sling on a classmate without much of an issue; and these simulated skills transfer pretty easily to a real life injuries.
Performing high-quality CPR is much different. You may have a perfect compression rate, and the correct compression:breath ratio, but was your mannequin effective at teaching the kinesthetics of how hard you actually need to compress the chest? Did it show you how the airway can be blocked with no head-tilt-chin-lift and blocked from tilting too far? Were you able to practice a jaw-thrust maneuver and utilize mask-mouth breathing where you visualized the chest rise?
High fidelity
We use equipment with a built in visual/tactile CPR feedback device which measures correct airway opening, compression depth/rate, and lung ventilation.
Realistic to the eye and the touch, Prestan manikins are equipped with a revolutionary ‘CPR Rate Monitor’ that allows for instant feedback to both instructor and student regarding the rate of chest compressions. The visual feedback from the CPR Rate Monitor gives students a real life feel of delivering 100-120 compressions per minute. Experience the true force needed to deliver real life chest compressions.
Features:
Advanced feedback parameters today are CPR rate, compression depth, and ventilation.
Patented face/head tilt simulates how an actual patient's head would move if they required CPR and teaches students how to properly open the airway.
Easily inserted face shield/lung bag provides visual chest rise to ensure students receive the most accurate and realistic training, also open nose holes to pinch the nose.
Located in the shoulder is a CPR Rate Monitor that provides instant visual feedback on compression rates – students know they are at the correct compression rate when two green lights illuminate. Experience the true force needed to deliver real life chest compressions.
Unique Clicker Mechanism provides an audible confirmation when the correct compression depth is reached, guiding to the appropriate force when administering CPR compressions.
The future of CPR Training
Delta Emergency Support Training has been using adult and infant Prestan Mannequins and AED trainers (more realistic as well!) from day one. They may be more expensive, but the feedback from every class about how CPR truly feels has been worth it. Everyone leaves our class more confident and comfortable knowing how to properly perform high quality CPR.
In 2021, the Heart and Stroke Foundation of Canada are making CPR Feedback Devices mandatory for all first aid/CPR courses. Prestan will be releasing an updated mannequin soon with 3 more advanced feedback parameters such as: Recoil, Ventilation and Hands Off Time, and the Bluetooth app screenshot you see above. The photos above show the mannequin, the Bluetooth app during CPR , and the physical module for the new features. When requested, we can also use a full-body mannequin simulator, and airway simulation equipment.
