The correct CPR ratio for adults is 30 compressions followed by 2 breaths, often written as 30:2. This ratio should be maintained for effective cardiopulmonary resuscitation.
CPR Ratio Explained
The 30:2 ratio applies to adult CPR when rescue breaths are being performed along with chest compressions.
- Compressions: The chest compressions should be performed at a rate of 100 to 120 per minute.
- Breaths: After every 30 chest compressions, 2 rescue breaths should be administered.
This cycle of 30 compressions and 2 breaths should be repeated continuously, aiming for about 5 sets within 2 minutes. If only compressions are given, the rate should also be 100 to 120 per minute.
Key Considerations for CPR
Understanding the correct CPR ratio is essential, but there are other important aspects to keep in mind:
- Depth of Compressions: Chest compressions should be deep enough (about 2 inches) to effectively circulate blood.
- Hand Placement: Proper hand placement on the sternum is critical to avoid injury.
- Continuity: Minimize interruptions to chest compressions to maximize effectiveness.
Here is a table summarizing the CPR ratio:
| Element | Ratio | Details |
|---|---|---|
| Compressions | 30 | Aim for 100-120 per minute |
| Rescue Breaths | 2 | Give after every set of 30 compressions |
Importance of the Correct CPR Ratio
Following the recommended 30:2 ratio is critical for performing effective CPR. This method maximizes the flow of oxygenated blood to vital organs, significantly improving the chance of survival.
Note: While the 30:2 ratio is standard for adults, CPR guidelines may vary for children and infants.
