Short Answer 
CPR is a critical procedure used in emergencies to restore circulation and breathing when the heart stops, significantly improving survival chances. Effective CPR involves key components like allowing the chest to fully recoil, maintaining a compression rate of 100-120 per minute, and using proper technique to ensure adequate depth and force during compressions.
Understand CPR and Its Purpose
Cardio-pulmonary resuscitation (CPR) is a critical emergency procedure performed when an individual’s heart stops beating. The main goal of CPR is to restore blood circulation and breathing to sustain life until professional medical help arrives. Being able to perform CPR can significantly increase the chances of survival for someone experiencing cardiac arrest.
Key Components of High-Quality CPR
To deliver effective CPR, adhere to the following vital components:
- The chest must return to its normal position after each compression to allow the heart to refill with blood.
- Maintain a compression rate of between 100 to 120 compressions per minute to ensure adequate blood flow.
- Each rescue breath should last at least 2 seconds, and you should observe for chest rise to confirm effective ventilation.
Technique for Chest Compressions
When performing chest compressions, it’s important to apply the correct technique. Aim for a depth of about 2 inches with each compression to create sufficient pressure on the heart. Follow these guidelines:
- Use your body weight to assist with compressions for better effectiveness.
- Keep your arms straight and shoulders directly above your hands to maximize force.
- Maintain a steady rhythm while aiming for 100 to 120 compressions per minute to keep blood circulating.
