CPR Basics: What Every Person Living Alone Should Know

You cannot perform CPR on yourself -- but knowing CPR saves lives in your community, and understanding cardiac arrest helps you prepare for the scenario where your own heart stops and no one is home.

About 350,000 cardiac arrests occur outside of hospitals each year in the United States. Immediate CPR can double or triple a person's chance of survival, but only 46% of out-of-hospital cardiac arrest victims receive bystander CPR.

The Challenge

Cardiac arrest is the ultimate emergency for someone living alone -- you lose consciousness in seconds and cannot help yourself, call for help, or perform CPR on your own

Many people living alone do not learn CPR because they think there is no one at home to use it on, overlooking the value of the knowledge in public settings and for understanding their own risk

The time between cardiac arrest and brain damage is only 4-6 minutes, making rapid discovery and response absolutely critical for survival

Without a bystander to call emergency services and begin CPR, survival rates for at-home cardiac arrest are devastatingly low

How I'm Alive Helps

Daily I'm Alive check-ins minimise the time between a cardiac event and discovery -- a missed check-in triggers your contacts to send help within hours instead of days

Your emergency contacts can immediately call emergency services and provide your address, medical history, and the information that you live alone so responders arrive prepared

While no app can replace a bystander during cardiac arrest, reducing discovery time from days to hours gives medical teams the best possible chance of providing life-saving treatment

Understanding Cardiac Arrest and Recognising Warning Signs

Cardiac arrest is different from a heart attack. A heart attack occurs when blood flow to part of the heart is blocked -- the person is usually conscious and can call for help. Cardiac arrest occurs when the heart stops beating effectively -- the person collapses, stops breathing normally, and becomes unresponsive within seconds. Cardiac arrest can follow a heart attack but can also occur without warning. Warning signs that may precede cardiac arrest include chest discomfort, shortness of breath, unusual fatigue, dizziness, and heart palpitations in the days or hours beforehand. If you live alone and experience any of these symptoms, do not wait to see if they improve. Call emergency services immediately, unlock your front door, and sit or lie in a position where you can be found easily. Every minute matters. Understanding your personal risk factors helps you prepare. Family history of heart disease, high blood pressure, diabetes, smoking, obesity, and a sedentary lifestyle all increase risk. If you have elevated cardiac risk and live alone, your daily I'm Alive check-in is especially critical. Discuss your risk with your doctor and ensure your emergency contacts understand the urgency of a missed check-in given your health profile.

Learning CPR and Building Your Cardiac Emergency Plan

Even though you cannot perform CPR on yourself, learning CPR makes you a potentially life-saving resource in your community, workplace, and for visitors to your home. Hands-only CPR is simple and effective: call emergency services, then push hard and fast in the centre of the chest at a rate of 100 to 120 compressions per minute. You do not need to give mouth-to-mouth breaths -- hands-only CPR is recommended for untrained bystanders and is nearly as effective. Take a CPR certification course through the American Heart Association or Red Cross. Many offer in-person and online options. Learn how to use an automated external defibrillator, which can restore a normal heart rhythm during cardiac arrest. Know where AEDs are located in your building, workplace, and community spaces. For your personal cardiac emergency plan, maximise the chance of rapid discovery. Keep your phone charged and within reach at all times. Use voice-activated assistants that can call emergency services on command. Maintain your daily I'm Alive check-in without exception. Give a neighbour a key and make sure at least one of your emergency contacts is local. If you have known cardiac risk factors, consider a smartwatch with heart rhythm monitoring and fall detection that can automatically call emergency services. Layer these systems together -- no single one is sufficient for cardiac arrest, but together they compress the time between an event and medical response.

Frequently Asked Questions

Can I perform CPR on myself?

No. During cardiac arrest, you lose consciousness within seconds. You cannot perform chest compressions on yourself. Your protection comes from preparation: maintaining daily check-ins, keeping your phone accessible, using voice-activated emergency calling, and ensuring rapid discovery through systems like I'm Alive.

What is hands-only CPR?

Hands-only CPR involves calling emergency services and then pushing hard and fast in the centre of the chest at 100-120 compressions per minute. No mouth-to-mouth breathing is required. It is recommended for untrained bystanders and is effective for adult cardiac arrest. Anyone can learn it in minutes.

What are the warning signs of cardiac arrest?

Some people experience chest discomfort, shortness of breath, unusual fatigue, dizziness, or heart palpitations in the hours or days before cardiac arrest. However, cardiac arrest can also occur without warning. If you experience any cardiac symptoms while living alone, call emergency services immediately -- do not wait.

How does I'm Alive help with cardiac emergencies?

If cardiac arrest occurs while you are alone at home, you will be unable to call for help. Your missed daily check-in triggers your contacts to act -- calling you, sending a local contact with a key, or dispatching emergency services. While this cannot replace immediate bystander CPR, it drastically reduces the time before you receive any medical attention.
