Correct CPR Compression Rate for a 7-Year-Old Child
The correct chest compression rate for a 7-year-old child is 100-120 compressions per minute. 1
Evidence-Based CPR Parameters for a 7-Year-Old
Compression Rate
- Rate should be approximately 100-120 compressions per minute 1
- This rate is supported by observational studies showing:
Compression Depth
- For a 7-year-old child, compress the chest to at least one-third of the anterior-posterior diameter of the chest 1
- This equates to approximately 2 inches (5 cm) in children 1
- CT-based studies confirm that one-third external anterior-posterior chest depth is appropriate for children aged 3 months to 8 years 2
Compression Technique
- Either a 1-hand or 2-hand technique may be used for chest compressions in a child this age 1
- Ensure complete chest recoil after each compression 1
- Perform compressions on a firm surface for optimal depth 1
Compression-to-Ventilation Ratio
- For single rescuer CPR: 30 compressions to 2 ventilations 1
- For 2 rescuers CPR: 15 compressions to 2 ventilations 1
Important Considerations for Effective CPR
Rescuer Fatigue
- CPR quality deteriorates significantly after 2 minutes of continuous compressions 3
- By 2 minutes, the percentage of adequate compressions falls below 70% 3
- Switch rescuers approximately every 2 minutes to maintain compression quality 1, 3
Monitoring CPR Quality
- For healthcare providers, perform rhythm checks lasting no more than 10 seconds approximately every 2 minutes 1
- Video review can accurately measure compression rate but not reliably assess depth and release 4
Common Pitfalls to Avoid
- Inadequate compression depth
- Incomplete chest recoil
- Excessive interruptions in chest compressions
- Compression rates outside the recommended range
- Rescuer fatigue affecting quality (switch every 2 minutes)
By following these evidence-based guidelines for chest compression rate and other CPR parameters, you can provide optimal cardiopulmonary resuscitation for a 7-year-old child in cardiac arrest, maximizing the chances for survival with good neurological outcomes.
