Step 1:I'll solve this by carefully reviewing each statement against current CPR guidelines:
Step 2:: Chest Returns to Normal Position Between Compressions
- This is a CORRECT component of high-quality CPR - Allows full chest recoil, which helps blood return to the heart - Ensures maximum blood flow during compressions
Step 3:: Compression Rate
- 100 to 120 compressions per minute is CORRECT - This specific rate is recommended by the American Heart Association - Ensures optimal blood circulation during cardiac arrest
Step 4:: Breath Duration and Chest Rise
- Each breath lasting at least 2 seconds with chest rise is CORRECT - Ensures adequate oxygen delivery to the lungs - Proper ventilation is crucial during CPR
Step 5:: Minimize Interruptions
- Keeping chest compression interruptions under 10 seconds is CORRECT - Continuous chest compressions are critical for maintaining blood flow - Minimizes disruption to circulation during resuscitation
Step 6:: Compression Depth
- At least 5 inches of compression depth is INCORRECT - Current guidelines recommend 2 - 2.4 inches (5 - 6 cm) for adults - Depth is important, but 5 inches would be too deep and potentially harmful
Step 7:: Checking Breathing
- Checking breathing every 30 seconds is INCORRECT - Current guidelines do not recommend routine breathing checks - Focus should remain on continuous chest compressions
Final Answer
1. Chest returns to normal position between compressions 2. Compression rate of 100 - 120 per minute 3. Each breath lasting at least 2 seconds with chest rise 4. Minimize interruptions in chest compressions to less than 10 seconds
