When you are in a park, someone suddenly collapses.
This person is unresponsive, not breathing-anyone can tell that their heart has stopped.
What will you do?
And this is where a Cardiac Science Defibrillator comes in-giving people their lives back.
This blog will guide you step by step through everything you need to know about using one.
This guide will give you the knowledge you need to confidently spring into action in an emergency-whether as an absolute beginner or just a refresher.
What is a Cardiac Science Defibrillator?
A Cardiac Science defibrillator, otherwise known as an automated external defibrillator is a portable device delivering a shock to the heart in the event of sudden cardiac arrest.
SCA occurs when the electrical impulses that regulate the heartbeat in the heart malfunction, causing the heart to beat irregularly or to stop altogether.
The defibrillator analyzes the heart's rhythm and, if necessary, provides a shock to get the heartbeat back in order.
These devices are extremely easy to use and come with full voice guidance and visual prompts.
They are commonly found in airports, gyms, and offices today, yet they are becoming more and more prevalent in homes and the community.

Why is it Important to Know How to Use One?
Every minute without defibrillation reduces survival by 7-10%.
Knowing how to use a defibrillator is so essential.
Medical professionals don't need to be the only ones learning how to use an ECG machine - anyone can and should learn how to operate one properly.
In an emergency situation, you could make all the difference.
A defibrillator can be likened to an emergency fire extinguisher; you hope you won't need it, but if the time ever arises, knowing how to use one could save a life.

How Does a Defibrillator Work?
Defibrillators work by monitoring the heart electrical activity.
If the device detects life-threatening arrhythmias (such as ventricular fibrillation or tachycardia), a controlled electric shock will be delivered for treatment.
This shock effectively "resets" the heart, enabling it to resume a normal rhythm.
Cardiac Science Defibrillators make AED use easy.
Their easy-to-use instructions guide users step by step through what to do for optimal use no medical knowledge is needed to use one.
Types of Defibrillators: AEDs vs. Manual Defibrillators
There are two main types of defibrillators: AEDs and manual defibrillators.
AEDs are designed for use by laypersons and are the type you’re most likely to encounter in public spaces.
They’re fully automated and guide you through the process with voice prompts.
Manual defibrillators, on the other hand, are used by medical professionals.
They require more training and expertise, as the user must interpret the heart rhythm and decide when to deliver a shock.
How to Use a Cardiac Science Defibrillator?
1. Safety Precautions Before Use:
Before using a defibrillator, it’s important to ensure the scene is safe.
Check for hazards like water, metal surfaces, or flammable materials.
If the person is wet, dry their chest before attaching the pads.
Also, make sure no one is touching the person when the defibrillator is analyzing or delivering a shock.
2. Checking the Equipment:
Most Cardiac Science Defibrillators perform a self-check when powered on, but it’s always a good idea to inspect the device.
Look for any visible damage, ensure the electrode pads are sealed and not expired, and check that the battery is charged.

Step-by-Step Guide to Using a Cardiac Science Defibrillator
Step 1: Assess the Situation:
The first step is to assess the person.
Are they unresponsive?
Tap their shoulder and shout, “Are you okay?”
If they don’t respond, check for breathing and a pulse. If they’re not breathing or only gasping, it’s time to act.
Step 2: Call for Help:
If you’re not alone, ask someone to call 112 (or your local emergency number) and bring the defibrillator.
If you’re alone, call 112 yourself before starting CPR or using the defibrillator.
Step 3: Turn On the Defibrillator:
Power on the Cardiac Science Defibrillator.
Most models have a clearly marked power button.
Once turned on, the device will guide you through the next steps with voice prompts.
Step 4: Attach the Electrode Pads:
Expose the person’s chest and attach the electrode pads as shown in the diagram on the pads.
One pad goes on the upper right side of the chest, and the other goes on the lower left side. Make sure the pads adhere firmly to the skin.
Step 5: Analyze the Heart Rhythm:
Once the pads are in place, the defibrillator will analyze the heart rhythm.
It will instruct you to stand clear and not touch the person during this process.
Step 6: Deliver the Shock (If advised):
If the defibrillator detects a shockable rhythm, it will prompt you to deliver a shock.
Make sure no one is touching the person, then press the shock button.
The person’s body may jerk when the shock is delivered this is normal.
Step 7: Perform CPR (If Necessary):
After the shock, the defibrillator will instruct you to start CPR if the person remains unresponsive.
Follow the CPR guidelines (30 chest compressions followed by 2 rescue breaths) until the defibrillator advises you to stop or emergency help arrives.
Post-Use Steps
What to Do After Using the Defibrillator?
Once the person regains consciousness or emergency responders arrive, turn off the defibrillator and remove the pads.
If the person is breathing and has a pulse, place them in the recovery position and monitor them until help arrives.
When to Seek Professional Medical Help?
Even if the person appears to recover, it’s essential to seek professional medical help immediately.
Sudden cardiac arrest can cause internal damage that isn’t immediately visible.
Maintenance and Care of Your Defibrillator
Regular Checks and Battery Replacement:
To ensure your defibrillator is always ready for use, perform regular checks.
Most devices have a status indicator that shows whether the battery and pads are in good condition.
Replace the battery and pads as needed and keep track of expiration dates.
Storing Your Defibrillator Properly:
Store your defibrillator in a cool, dry place, away from direct sunlight and extreme temperatures.
Make sure it’s easily accessible in case of an emergency.
Common Mistakes to Avoid When Using a Defibrillator
Incorrect Pad Placement:
One of the most common mistakes is placing the pads incorrectly. Always follow the diagram on the pads to ensure proper placement.
Delaying Use:
Time is critical in a cardiac emergency.
Don’t hesitate to use the defibrillator as soon as possible. Remember, every second counts.
Conclusion
Knowing how to use a Cardiac Science Defibrillator can save a life.
It’s a simple yet powerful tool that anyone can use, even without medical training.
By following this step-by-step guide, you’ll be prepared to act quickly and confidently in an emergency.
Remember, the key is to stay calm, follow the prompts, and trust the device to guide you.
FAQs
Can I hurt someone by using a defibrillator incorrectly?
No, modern AEDs like the Cardiac Science Defibrillator are designed to only deliver a shock if it’s needed. You can’t accidentally harm someone by using one.
Do I need training to use a Cardiac Science Defibrillator?
While training is helpful, it’s not required. The device provides clear voice and visual instructions to guide you through the process.
Can I use a defibrillator on a child?
Yes, but you may need to use pediatric pads or a pediatric setting if available. Always check the device’s instructions.
How often should I check my defibrillator?
Perform a monthly check to ensure the battery and pads are in good condition. Replace them as needed.
What should I do if the defibrillator doesn’t advise a shock?
If the device doesn’t advise a shock, continue performing CPR until emergency help arrives or the person regains consciousness.
