In the realm of life-saving techniques, Cardiopulmonary Resuscitation (CPR) is one of the most well-known and widely taught procedures. CPR has the power to sustain life during critical moments, such as cardiac arrest, by manually pumping blood to vital organs, keeping the brain and heart alive until professional medical care can intervene.

Critical Component |
Chest Compressions |
|
Purpose of Compressions |
Manually pumps blood to vital organs, particularly the brain and heart, during cardiac arrest. |
|
Compression Rate |
100-120 compressions per minute |
|
Compression Depth |
For adults: at least 2 inches (5 cm); for children: about 2 inches; for infants: about 1.5 inches (4 cm) |
|
Full Chest Recoil |
Allow the chest to fully return after each compression to maximize blood flow. |
|
When to Use Rescue Breaths |
Required for children, infants, and cases of respiratory-related arrest (drowning, overdose), but optional in adult cardiac arrest if untrained. |
|
Hands-Only CPR |
Only chest compressions without rescue breaths, recommended for untrained bystanders in adult cardiac arrest situations. |
|
When to Stop CPR |
Stop if the person shows signs of life, a defibrillator or emergency help arrives, or you’re physically unable to continue. |
|
Importance of Training |
Increases confidence and accuracy in performing CPR, improves survival rates, and ensures proper technique for compressions and breaths. |
|
Bystander Impact |
Immediate chest compressions by a bystander can double or triple the survival chances in out-of-hospital cardiac arrest. |

What is CPR?
Cardiopulmonary resuscitation (CPR) is an emergency procedure consisting of chest compressions combined with artificial ventilation to manually preserve brain function until further measures can be taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest. Cardiac arrest is a state where the heart ceases to pump blood due to electrical or mechanical issues within the heart muscle. During cardiac arrest, the body cannot circulate blood, which means that vital organs such as the brain, lungs, and other tissues do not receive oxygen, and irreversible damage begins to set in within minutes.
Why Chest Compressions Are the Core of CPR
Cardiac arrest is a condition where the heart suddenly stops beating effectively, halting the flow of blood throughout the body. Without blood flow, the brain and other vital organs are deprived of oxygen and nutrients, leading to irreversible damage within minutes. Here’s where chest compressions become indispensable in CPR: their primary purpose is to manually pump blood, providing oxygen to organs even when the heart fails.
Chest compressions simulate the natural pumping action of the heart, allowing blood to circulate through the body. This simple but powerful action, when performed correctly, can double or even triple a person’s chances of survival in an out-of-hospital cardiac arrest (OHCA) setting.
How Chest Compressions Work
When you press down on a person’s chest, you compress the heart between the sternum and spine, forcing blood out of the heart and into the circulatory system. Upon releasing the compression, the heart re-expands, drawing in blood. Each compression thus acts as a makeshift “beat,” which, when sustained at the recommended rate of 100-120 compressions per minute, can maintain sufficient blood flow to the brain and other organs.
By keeping a regular rhythm and proper depth during compressions, rescuers can maintain some level of oxygenated blood flow even before professional medical interventions, like defibrillation, become available.

Key Elements of Effective Chest Compressions
-
Proper Rate:
The recommended rate for chest compressions is 100-120 compressions per minute. Moving too quickly or too slowly can reduce the effectiveness of CPR by either not providing adequate blood flow or not allowing the heart to refill between compressions. -
Adequate Depth:
For adult CPR, compressions should be at least two inches (5 cm) deep. Compressing too shallowly may not provide enough pressure to circulate blood, while compressing too deeply could cause rib fractures, though the latter risk is generally outweighed by the need to save the individual’s life. -
Full Chest Recoil:
Allowing the chest to fully recoil after each compression is crucial. Without full recoil, the heart doesn’t refill with enough blood between compressions, reducing the volume of blood pumped with each beat and compromising the effectiveness of CPR. -
Consistency and Endurance:
Sustaining chest compressions can be physically challenging, especially if the emergency lasts more than a few minutes. However, consistency in rate and depth is essential for maintaining blood flow. In situations where multiple rescuers are present, rotating every two minutes can prevent fatigue and help maintain effective compressions.

Why Chest Compressions Are Critical for All CPR Types
Whether it’s hands-only CPR or the traditional method that includes rescue breaths, chest compressions remain the core component. In cases of sudden cardiac arrest, the initial priority is to restore circulation rather than breathing, as the lack of blood flow to the brain and heart presents the most immediate danger.
- For Adults: The vast majority of cardiac arrests in adults are related to heart issues rather than respiratory problems. Therefore, chest compressions are the primary life-sustaining measure.
- For Children and Infants: While rescue breaths are crucial for children and infants, chest compressions are still needed to keep blood circulating and to assist in delivering oxygen from breaths to the brain and other organs.
