Hands-Only or Full CPR? The 2025 Guidelines Finally Cleared Up What Bystanders Should Do

Excerpt: A year after the 2025 adult basic life support recommendations were published, the practical message is clear: start CPR rather than hesitate. If you’re untrained or unwilling to give breaths, use hands-only CPR; if you’re trained and willing, add breaths, especially when the person is a child or the cause may involve a lack of oxygen.

It’s been a year since the American Heart Association published its 2025 adult basic life support guidelines on October 22, 2025. One question I hear often in CPR training is: Should a bystander give hands-only CPR or include rescue breaths?

The short answer is that both approaches have a place. If you’re untrained, unable, or unwilling to give breaths, hands-only CPR is an appropriate way to help an adult in cardiac arrest. If you’re trained and willing, conventional CPR with compressions and breaths is recommended, and breaths are particularly important for infants, children, and emergencies where a lack of oxygen may have caused the arrest.

The most important point is not to freeze while deciding. Call 911 and begin CPR. CPR can help sustain circulation until emergency medical professionals arrive, but it does not guarantee survival and never replaces calling 911.

The simple decision: Do what you can, without delaying

When someone collapses, it can be hard to tell what has happened. If the person is unresponsive and not breathing normally, or is only gasping, treat it as an emergency.

Use this practical sequence:

1. Make sure the scene is safe.
2. Call 911. If you have a mobile phone, use speakerphone so you can talk with the dispatcher while starting CPR. Follow the dispatcher’s instructions.
3. Start chest compressions. If you’re not trained in CPR or aren’t able or willing to give breaths, continue hands-only compressions for an adult.
4. If you’re trained and willing to give breaths, use conventional CPR. For an adult without an advanced airway, that generally means 30 compressions followed by 2 breaths.
5. Keep going until help takes over, the person shows signs of life, or you can’t continue.

Dispatcher-assisted CPR is valuable because the person on the phone can guide you through what to do. Using speakerphone helps you get those instructions while keeping your hands free to begin compressions.

Hands-only CPR is a valid response, not a reason to wait

Hands-only CPR means giving continuous chest compressions without rescue breaths. The 2025 recommendations support it for untrained bystanders responding to suspected adult cardiac arrest. It’s also appropriate if a person is unable or unwilling to give breaths.

That matters because hesitation can cost time. You don’t need to be certified to call 911 and begin hands-only CPR on an adult. If you’re unsure what to do, call emergency services, put your phone on speaker, and follow the dispatcher’s guidance.

AHA data also highlight how much bystander action matters: only about 41.7% of adults with EMS-treated out-of-hospital cardiac arrest received bystander CPR. That figure describes how often CPR was started. It is not a measure of how effective hands-only CPR is. Still, it underscores the need for more people to feel ready to act.

When trained rescuers should add breaths

For trained rescuers who are willing and able, the guidelines encourage CPR that includes breaths as well as compressions. For adult CPR without an advanced airway, the usual ratio is 30 compressions to 2 breaths.

Give each breath in a way that produces a visible rise in the chest. Depending on your training and available equipment, that may mean mouth-to-mouth breaths or using a pocket mask. If breaths are not possible, keep doing compressions rather than stopping altogether.

Compression quality matters, too. For adults, aim for a rate of 100 to 120 compressions per minute and a depth of at least 5 cm (about 2 inches), but no more than 6 cm (about 2.4 inches). Allow the chest to return fully between compressions and minimize interruptions.

Why age and cause of the emergency matter

A sudden cardiac arrest in an adult is not the only situation in which CPR may be needed. Children and infants are more likely than adults to experience cardiac arrest following a breathing emergency or another problem that limits oxygen. In those situations, breaths are especially important.

The same concern applies when an arrest may be related to an asphyxial cause, such as drowning or an overdose. This doesn’t mean a bystander should delay compressions if they don’t know how to give breaths. It means that someone who is trained and willing should use conventional CPR rather than defaulting to hands-only in every situation.

Adult compression targets don’t apply to children and infants. Pediatric CPR uses age-appropriate techniques and compression depths. If you care for children, ask specifically for training that includes infant and child CPR rather than assuming an adult-only class covers it.

The point is to act, not to perform perfectly

The updated recommendations clarify the choices, but they don’t change the priority: get emergency help and start CPR promptly. If you’re untrained, hands-only CPR is a useful response. If you’re trained and willing, give compressions and breaths. Use speakerphone to get dispatcher assistance, and follow the instructions you receive.

I teach practical, hands-on and blended courses that help participants practice what to do, not just read about it. My courses include American Red Cross training programs, including First Aid + CPR/AED (All Ages). HSI certification is available only when a client specifically requests it. Training can help you build confidence, but no course or CPR method can promise a particular outcome. CPR does not guarantee survival, and it does not replace calling 911.

I provide appointment-only training and travel to client locations across San Diego County, Temecula, Murrieta, Menifee, Lake Elsinore, and Rancho Murrieta. To request a class, contact me online, email d.onori@codebluesafetyskills.com, or call (951) 669-4177. Please include the specific dates you want for the class, your preferred location, the course you need, and your group size.
