How CPR Works and When to Use It

CPR (cardiopulmonary resuscitation) works by maintaining blood circulation and oxygen delivery to vital organs when the heart stops, and should be used when a person is unresponsive and not breathing normally.

How CPR Works

CPR uses chest compressions to manually circulate blood and maintain oxygen supply to the brain and vital organs. This helps preserve organ function until advanced medical care or defibrillation can restore a normal heart rhythm.

  • Chest compressions create artificial blood circulation
  • Maintains oxygen delivery to the brain
  • Buys time before AED use or advanced care

When to Use CPR

CPR should be started immediately if a person:

  • Is unresponsive
  • Is not breathing normally or only gasping
  • Shows signs of cardiac arrest

In China, emergency medical services can be accessed by calling 120, but CPR should begin immediately without waiting for ambulance arrival.

Basic CPR Steps

  • Ensure the scene is safe
  • Check responsiveness and breathing
  • Call 120 or instruct someone else to call
  • Start chest compressions (center of the chest)
  • Continue compressions until help arrives or an AED is available

CPR and AED Together

CPR is most effective when combined with AED use. While CPR maintains circulation, an AED can restore a normal heart rhythm in certain cardiac arrest cases.

CPR in China: Practical Considerations

  • Emergency response times may vary by city and location
  • Bystander CPR is critical before ambulance arrival
  • Public awareness of CPR is increasing in major cities like Shanghai
  • Workplaces and schools are key environments for trained responders

Common Mistakes in CPR

  • Delaying CPR while waiting for professional help
  • Incorrect hand placement
  • Insufficient compression depth or rate
  • Stopping compressions too frequently

Why CPR Training Matters

High-quality CPR significantly improves survival outcomes in cardiac arrest situations. Training helps individuals perform compressions correctly, respond faster, and act with confidence in real emergencies.

CPR Training in Shanghai China

Structured CPR training programs in Shanghai China provide hands-on practice and scenario-based learning for individuals and organizations. Training is available in English and Chinese and can be adapted for workplace environments.
