Compressions During a Cardiac Arrest at Home: A Family Guide
Posted by Sydney Pulse, APRN at 8:08 am 0 Comment Print
Most people picture cardiac arrest happening in public. They imagine a sports field or a restaurant. The data tells a different story. The majority of adult cardiac arrests happen inside private homes, according to the American Heart Association’s 2025 CPR and ECC Guidelines. That means the person doing chest compressions is often a spouse, a parent, or a teenager, not a paramedic.
This guide walks families through compressions during a cardiac arrest at home. You’ll learn why speed matters so much, and how to prepare before an emergency ever happens.
Why Home Cardiac Arrest Is a Family Issue
Cardiac arrest strikes without warning. The heart stops pumping blood, and the person collapses within seconds. Without immediate help, blood flow to the brain drops to zero.
Here’s the hard truth: only 42.5% of out-of-hospital cardiac arrest patients receive bystander CPR nationally. That’s according to the 2025 CARES Annual Report. That number climbs past 50% when someone actually witnesses the collapse. At home, family members are almost always the ones who witness it.
Survival depends heavily on those first few minutes. Bystander CPR raises survival to hospital discharge to 13.0%. Without it, that number falls to 7.6%. Every minute without compressions cuts survival odds further, so hesitation costs lives.
Recognize It Fast
A person in cardiac arrest suddenly collapses. They stop responding. They either stop breathing or gasp in an abnormal pattern called agonal breathing. This is not a fainting spell, and it is not a seizure.
Check for responsiveness first. Tap the person’s shoulder and shout their name. If they don’t respond and aren’t breathing normally, treat it as cardiac arrest immediately.
Call 911 Before You Start Compressions
Call 911 first, or have someone else call while you begin compressions. Put the phone on speaker so the dispatcher can guide you. Many 911 centers, including those serving Jefferson County, now offer telecommunicator-assisted CPR. Dispatchers walk callers through compressions in real time.
If someone else is nearby, send them for an AED. More Louisville homes, gyms, and apartment complexes now stock automated external defibrillators. Pairing an AED with compressions dramatically improves outcomes.
How to Perform Compressions Correctly
Hands-only CPR is the recommended method for adults who collapse suddenly at home. You don’t need rescue breaths to make a difference.
Follow these steps:
- Kneel beside the person on a firm, flat surface.
- Place the heel of one hand on the center of the chest, between the nipples.
- Place your other hand on top and interlace your fingers.
- Lock your elbows and position your shoulders directly over your hands.
- Push hard and fast, at least 2 inches deep for adults.
- Let the chest fully recoil between compressions.
- Aim for 100 to 120 compressions per minute, about the tempo of “Stayin’ Alive.”
Keep going until paramedics arrive or an AED tells you to stop. Compressions are tiring. Switch with another person every two minutes if one is available. Compression quality drops fast once fatigue sets in.
Common Mistakes Families Make
Fear often leads to compressions that are too shallow or too slow. Push harder than feels natural. Broken ribs happen sometimes, but a cracked rib heals. A starved brain does not.
Another common error is stopping too soon. Family members often pause once the person gasps or twitches, assuming they’ve woken up. Agonal gasps are a sign of cardiac arrest, not recovery. Keep compressing.
Finally, don’t wait for perfect hand placement before you start. Approximate placement in the center of the chest beats delayed compressions while you search for the “right” spot.
Children and Infants Need a Different Approach
Compressions for kids differ from adult technique. For children roughly age 1 to puberty, use one or two hands based on the child’s size. Press about 2 inches deep. For infants under age 1, use two fingers or the two-thumb encircling technique. The AHA now recommends the two-thumb method for a lone rescuer.
Pediatric cardiac arrest at home is rare but devastating when it happens. Parents and caregivers benefit from PALS-level training. It covers pediatric compression depth, rescue breathing ratios, and AED pad placement for small children.
After You Start: What Happens Next
Once EMS arrives, they take over compressions and attach monitoring equipment. They transport the person to a hospital equipped for post-cardiac-arrest care. Louisville families live close to major systems like Norton Healthcare and UofL Health. Both manage the critical care that follows resuscitation.
Your job as a bystander ends when trained responders arrive. What you do in those first few minutes, though, often decides whether the person makes it to the hospital at all.
Get Trained Before You Need It
Reading about compressions helps, but muscle memory saves lives. Hands-on practice teaches your body the correct depth, rate, and rhythm. You won’t have to think it through during a real emergency.
CPR Louisville is an American Heart Association training site. We offer hands-on, stress-free classes for families, caregivers, and healthcare professionals across Jefferson County. Sign up for CPR certification Louisville to learn adult, child, and infant compressions from a certified instructor. If your household includes young children, grandchildren, or kids you babysit, consider PALS certification Louisville for a deeper look at pediatric emergencies, including cardiac arrest, respiratory distress, and choking response.
