# Chest Compressions

[Resources](https://www.australiawidefirstaid.com/resources) › [Glossary](https://www.australiawidefirstaid.com/resources/glossary)

## What are Chest Compressions?

Chest compressions are a crucial component of CPR, used to manually pump blood through the heart and to the rest of the body.

Chest compressions are a crucial component of cardiopulmonary resuscitation (CPR) used to maintain blood circulation in a person who has suffered cardiac arrest. The primary goal of chest compressions is to manually pump blood through the heart to the brain and other vital organs. Proper technique involves placing the heel of one hand on the center of the chest, with the other hand on top, and pressing down hard and fast at a rate of 100-120 compressions per minute. The chest should be compressed about one-third of its depth, allowing full recoil between compressions to maximize blood flow.

Consistency and rhythm are key to effective chest compressions. Interruptions should be minimized to maintain the flow of oxygenated blood. For children, use one hand, and for infants, use two fingers for compressions, adjusting the force accordingly. Chest compressions are often performed in conjunction with rescue breaths, but in some cases, compression-only CPR may be advised, particularly if the rescuer is untrained or unable to provide breaths. Continuous training and practice are essential for maintaining proficiency in performing chest compressions, as they are a critical skill in saving lives during cardiac emergencies.

## Performing Chest Compressions

1. Hand Placement: Place the heel of one hand in the center of the chest, with the other hand on top.
2. Compression Depth: Push down hard and fast, at least 2 inches deep.
3. Compression Rate: Aim for a rate of 100-120 compressions per minute.
4. Allow Full Recoil: Let the chest rise completely between compressions.
