The recommended rate for chest compressions is 100 to 120 compressions per minute. This target applies to adults, children, and infants, and it’s the same whether you’re performing hands-only CPR or conventional CPR with rescue breaths. The American Heart Association’s 2025 guidelines, the most current available, maintain this range as the standard.
Why 100 to 120 Per Minute
That specific range exists because of how blood moves through the body during CPR. Each compression physically squeezes the heart between the breastbone and spine, pushing blood out to the brain and vital organs. Between compressions, the heart refills. The rate you compress determines how much total blood flow you generate.
Both animal and human studies have found that blood flow peaks at compression rates near 120 per minute. A large study published in Circulation found a curvilinear relationship between compression rate and survival: the likelihood of a heartbeat returning peaked at roughly 125 compressions per minute, then declined. Rates above 140 per minute caused compression depth to drop significantly, meaning each individual push moved less blood even though pushes were happening faster. The heart simply doesn’t have time to refill between compressions at very high rates.
Going too slow is equally problematic. Below 100 per minute, total blood delivery drops and the brain and heart receive less oxygen. The 100 to 120 window balances fast enough to maintain circulation with slow enough to allow the heart to fill between pushes.
How to Hit the Right Tempo
A practical trick recommended by the American Heart Association: push to the beat of “Stayin’ Alive” by the Bee Gees, which plays at about 100 beats per minute. That gives you the minimum target rate. Other songs in the 100 to 120 BPM range work too. The key is finding a rhythm you can maintain steadily without speeding up as adrenaline kicks in.
If you have access to a CPR feedback device, whether on an AED or a smartphone app, it can give you real-time guidance on your rate. Without one, an internal beat from a familiar song is the most reliable method.
Rate Is Only One Part of Quality
Compression rate matters, but hitting 100 to 120 per minute won’t help much if other elements are off. High-quality CPR has several components that work together:
- Depth: Each compression should push the chest down at least 2 inches (5 centimeters) in adults. Children need about the same depth. Shallow compressions don’t generate enough pressure to move blood effectively.
- Full chest recoil: After each push, let the chest come all the way back up before compressing again. “Leaning,” where you keep pressure on the chest between compressions, reduces blood flow back to the heart. Animal studies show incomplete recoil decreases both coronary and brain perfusion pressure.
- Minimal interruptions: Every time you stop compressing, blood flow drops to near zero and takes several compressions to rebuild. Pauses for rescue breaths, rhythm checks, or switching rescuers should be as short as possible.
- Compression-to-breath ratio: For standard CPR, perform 30 compressions followed by 2 breaths per cycle. This ratio applies to both single-rescuer and two-rescuer situations before advanced airway equipment arrives.
Hands-Only CPR Uses the Same Rate
If you witness a teen or adult suddenly collapse, you don’t need to give rescue breaths. Hands-only CPR, which involves calling 911 and then pushing hard and fast in the center of the chest, has been shown to be as effective as conventional CPR with breaths during the first several minutes of a sudden cardiac arrest in adults. The compression rate stays the same: 100 to 120 per minute.
Rescue breaths remain recommended for infants, children, drowning victims, drug overdose cases, and anyone who collapsed due to a breathing problem. In these situations, oxygen depletion is often the primary issue, so breaths provide a meaningful benefit.
Switch Rescuers Every 2 Minutes
Performing chest compressions is physically exhausting. Research shows that compression quality, particularly depth, deteriorates over time even when rescuers don’t feel tired yet. The AHA recommends switching the person doing compressions approximately every 2 minutes, which works out to about 5 cycles of 30 compressions and 2 breaths.
The switch itself should take no more than a few seconds. If two people are present, the second rescuer should be positioned and ready to take over immediately. Compression rate tends to stay adequate longer than depth does, so fatigue often shows up as compressions becoming too shallow before they become too slow. Rotating rescuers helps maintain both.
Compression Guidelines for Children and Infants
The target rate of 100 to 120 compressions per minute is the same for pediatric patients. A multicenter study of in-hospital pediatric cardiac arrests found that blood pressure was higher when compression rates stayed between 100 and 120 per minute compared to rates exceeding 120. So the “faster is better” instinct that can take over in a stressful moment is just as counterproductive with children as with adults.
What differs is technique. For children ages 1 to 8, using two hands to compress produces better depth than one hand. For infants, the 2025 AHA guidelines recommend either a one-hand technique or a two-thumb encircling hands technique, where you wrap both hands around the infant’s torso and compress with your thumbs. The older two-finger method along the breastbone has been removed from guidelines because it doesn’t achieve adequate depth. Children who have reached puberty should be treated using adult CPR guidelines.
