Types of CPR: Hands-Only, Conventional and Age-Specific
“Types of CPR” usually refers to different ways of organizing compressions, breaths and team roles. Hands-only CPR uses continuous chest compressions. Conventional CPR combines compressions with rescue breaths. Pediatric and two-rescuer sequences adapt technique to age and team capacity.
The right approach depends on training, age, cause and dispatcher guidance. Sudden adult collapse may be appropriate for hands-only CPR by an untrained bystander, while children, infants, drowning and breathing-related arrests make ventilation especially important.
Types of CPR decision guide
Use this table to connect a visible scene cue with a safe response and a clear first-aid boundary.
| Priority | What can go wrong | Useful action |
|---|---|---|
| Hands-only CPR | Continuous compressions can help an untrained bystander begin quickly during sudden adult collapse. | Call 911 and follow dispatcher pacing and hand-position guidance. |
| Conventional CPR | Compressions with rescue breaths support both circulation and ventilation. | Use the trained ratio and minimize pauses. |
| Pediatric CPR | Children and infants use age-specific hand positions, depths and ventilation emphasis. | Practice on appropriate manikins and learn one- and two-rescuer sequences. |
| Two-rescuer CPR | A second trained person can divide compressions, breaths and AED tasks. | Assign roles and rotate without long interruptions. |
| Barrier-assisted breaths | A mask or shield can support seal and exposure protection. | Keep the barrier accessible and practice setup before an emergency. |
Choose by context, not preference
Call 911, identify the person’s age category and follow current training. Use hands-only CPR when directed for sudden adult collapse; include trained breaths when the situation and instruction call for them.
Do not mix sequences from memory or copy adult technique onto an infant. Professional resuscitation includes skills and equipment beyond lay-responder scope.
Hands-only used for the wrong scenario
A trained responder uses hands-only CPR after a child is pulled from water because it feels simpler. Another trained rescuer recognizes the oxygen-related arrest and adds age-appropriate breaths while 911 is active.
Simplicity is useful only when it matches the event. Cause and age change the value of ventilation.
Hands-only CPR
Continuous compressions can help an untrained bystander begin quickly during sudden adult collapse. In a stressful scene, this is where a small decision can either preserve momentum or create a distracting delay.
Call 911 and follow dispatcher pacing and hand-position guidance. State the action aloud, assign it to one person and confirm that it happened. A useful response is controlled and visible rather than dramatic.
Conventional CPR
Compressions with rescue breaths support both circulation and ventilation. This principle becomes easier to remember when it is connected to a specific cue.
Use the trained ratio and minimize pauses. Describe what you can see, hear or verify without guessing at the cause. Then use current training and live instructions to decide what comes next.
Pediatric CPR
Children and infants use age-specific hand positions, depths and ventilation emphasis. The safest boundary is the point at which basic first aid stops and professional assessment begins.
Practice on appropriate manikins and learn one- and two-rescuer sequences. Do not let a familiar-looking symptom create false reassurance. When the pattern is severe, changing or uncertain, early escalation is the practical choice.
Two-rescuer CPR
A second trained person can divide compressions, breaths and AED tasks. Preparation reduces the number of decisions that must be invented during the emergency.
Assign roles and rotate without long interruptions. Equipment, roles and communication should support the skill rather than compete with it. Afterward, document any gap that should be corrected before the next event.
Barrier-assisted breaths
A mask or shield can support seal and exposure protection. The distinction matters because a responder works from observable facts, not a private diagnosis.
Keep the barrier accessible and practice setup before an emergency. Keep the next step plain enough that another bystander can repeat it back. That protects the urgent priority while professional help is being activated.
Professional variations
Healthcare teams may use advanced airways, monitoring and coordinated medication or rhythm protocols. In a stressful scene, this is where a small decision can either preserve momentum or create a distracting delay.
Do not imitate advanced care without the role, training and equipment. State the action aloud, assign it to one person and confirm that it happened. A useful response is controlled and visible rather than dramatic.
Where a reasonable response can go off track
Fast care is not the same as rushed care. A useful response protects the first life-saving priority while avoiding actions that add injury, delay or confusion. Review these traps during practice so the correction is available before stress narrows attention.
Two-rescuer CPR
Another trap is allowing the search for equipment or certainty to replace the priority already in front of the responder. A second trained person can divide compressions, breaths and AED tasks. The safer correction is specific: Assign roles and rotate without long interruptions. Confirm the action aloud and keep watching for a change that requires 911, CPR or another trained response.
Barrier-assisted breaths
Teams also lose time when several people start the same task while no one owns the emergency call or handoff. A mask or shield can support seal and exposure protection. The safer correction is specific: Keep the barrier accessible and practice setup before an emergency. Confirm the action aloud and keep watching for a change that requires 911, CPR or another trained response.
Professional variations
The appearance of improvement can create false reassurance when no one keeps monitoring the original warning signs. Healthcare teams may use advanced airways, monitoring and coordinated medication or rhythm protocols. The safer correction is specific: Do not imitate advanced care without the role, training and equipment. Confirm the action aloud and keep watching for a change that requires 911, CPR or another trained response.
Make the response visible and repeatable
A short tabletop exercise can expose confusion without asking anyone to act out an injury. Use a manikin or training device when physical skill practice is appropriate. Never rehearse an emergency maneuver on an unsuspecting person, and stop any exercise that becomes unsafe.
- Hands-only CPR: Remove one helper from the scenario and decide which priority must still be protected.
- Conventional CPR: Add noise or limited space, then practice giving one clear instruction at a time.
- Pediatric CPR: Identify the exact moment when first aid reaches its limit and professional guidance is needed.
- Two-rescuer CPR: Finish with the location, the person’s condition, actions taken and any meaningful change.
- Barrier-assisted breaths: Name the observable cue, the first action and the person responsible for calling 911.
Run the scene once with the supplies and people normally available. On the second pass, change one condition: the phone cannot connect immediately, the usual kit is missing, the space is crowded or the person cannot answer questions. The purpose is not to invent advanced treatment. It is to preserve scene safety, emergency activation, the highest-priority first-aid action and a clear handoff.
Debrief with evidence instead of impressions. Ask what was noticed first, how long it took to assign the emergency call, which words caused confusion and whether anyone crossed a training boundary. Record one correction, give it an owner and repeat the drill after the correction is made. That is how a reading exercise becomes a practical readiness improvement.
Frequently asked questions
Is hands-only CPR always enough?
No. It is particularly promoted for untrained response to sudden adult collapse. Other arrests benefit from trained breaths.
Does AED use create another type of CPR?
No. The AED is integrated into CPR and analyzes whether defibrillation is indicated.
What if I am unsure whether breathing is normal?
Call 911, use speaker mode and describe exactly what you see and hear. Gasping is not normal breathing, and the dispatcher can guide the response.
Should I wait for someone more experienced?
No. Activate emergency services and begin the response you are trained or directed to provide. Waiting without acting loses time.
