CPR Ratio Chart
| Age Group | Compression-to-Breaths Ratio | Compression Rate | Compression Depth | Rescue Breaths |
|---|---|---|---|---|
| Adult | 30:2 | 100-120/min | About 2 inches | 2 breaths after every 30 compressions |
| Child | 30:2 | 100-120/min | About one-third to one-half the depth of the chest (about 2 inches or 5 centimeters) | 2 breaths after every 30 compressions |
| Infant | 30:2 | 100-120/min | About one-third the depth of the chest (about 1.5 inches or 4 centimeters) | 2 breaths after every 30 compressions |
CPR (Cardiopulmonary Resuscitation) is an emergency procedure used to manually keep a person's blood circulation and breathing going when their heart has stopped. The CPR ratio refers to the number of chest compressions to rescue breaths given during CPR. The standard CPR ratio for adults, children, and infants has traditionally been 30 compressions to 2 breaths. However, it's important to note that guidelines and recommendations for CPR may vary based on the specific organization or region.
Here's a general overview of the CPR ratio chart for different age groups:
Adult CPR (one-rescuer):
- Compression-to-breaths ratio: 30:2
- Compressions: 30 chest compressions at a rate of 100-120 compressions per minute
- Breaths: 2 rescue breaths after every 30 compressions
Child CPR (one-rescuer):
- Compression-to-breaths ratio: 30:2
- Compressions: 30 chest compressions at a rate of 100-120 compressions per minute (about one-third to one-half the depth of the chest, approximately 2 inches or 5 centimeters)
- Breaths: 2 rescue breaths after every 30 compressions
Infant CPR (one-rescuer):
- Compression-to-breaths ratio: 30:2
- Compressions: 30 chest compressions at a rate of 100-120 compressions per minute (about one-third the depth of the chest, approximately 1.5 inches or 4 centimeters)
- Breaths: 2 rescue breaths after every 30 compressions
It's important to note that if there are two rescuers present, the compression-to-breaths ratio may change to 15:2 for both adult and child CPR.
Key numbers to remember during CPR include:
- Compression rate: 100-120 compressions per minute
- Compression depth:
- Adults: about 2 inches (5 centimeters)
- Children: about one-third to one-half the depth of the chest (about 2 inches or 5 centimeters)
- Infants: about one-third the depth of the chest (about 1.5 inches or 4 centimeters)
- Rescue breaths: 2 breaths after every set of compressions (30 compressions)
- Call for emergency help (such as 911) as soon as possible when CPR is initiated.
It's important to receive proper CPR training and certification from a reputable organization to ensure you are up-to-date with the latest guidelines and techniques. Remember that these ratios and numbers may vary slightly depending on the specific guidelines followed in your region.
