Cardiac arrests can happen suddenly and without warning, making it crucial for bystanders to know how to respond. One of the most vital life-saving techniques you can use in such a situation is CPR or cardiopulmonary resuscitation.

When performing CPR, understanding what is the proper depth of compressions is key to ensuring that the victim receives adequate blood flow to their brain and heart until medical help arrives.

This article will guide you through the important details regarding the depth of compressions, why it matters, and how to perform CPR effectively.

The Importance of Compression Depth

When performing CPR, the primary goal is to keep blood circulating in a person’s body. The heart usually pumps blood at its normal rhythm. However, during a cardiac arrest, this rhythm stops, and that’s where the right depth of compressions becomes essential.

Knowing the proper depth of compressions is vital because it ensures enough pressure is generated to move blood through the heart and into vital organs. For adults, the correct CPR depth is about two to two and a half inches (five to six centimeters).

For children, the depth is around one-and-a-half inches (four centimeters), and for infants, it should be about one and a half inches deep as well, using two fingers to apply the pressure. These measurements may seem small but they are significant enough to maintain effective blood flow and improve the chances of survival.

How to Achieve the Right Depth of Compression

Knowing how to achieve the correct depth of compressions is only half of the procedure. To do it properly, you need to position your hands correctly on the person’s chest.

Make sure the person is lying on their back on a firm and flat surface. This allows for better pressure application.

Place the heel of one hand in the center of the chest, just above the lower half of the breastbone. Put the other hand on top and interlock your fingers. This stabilizes your hands for accurate compressions.

Keep your elbows straight and use your body weight to push down. This method helps you achieve the necessary depth without exhausting yourself too quickly.

Compress the chest at a rate of 100 to 120 compressions per minute. This is the ideal pace to maintain blood flow effectively.

Common Misconceptions About CPR and Compression Depth

Many people have myths about CPR that can lead to improper techniques. One common belief is that compressions do not need to be hard enough. However, that couldn’t be further from the truth.

Inadequate pressure during compressions may hinder blood flow, resulting in ineffective CPR. Remember, performing CPR is better than doing nothing at all, even if you’re unsure.

Another misconception is that you can’t harm someone with compressions. While it’s true that rough handling can cause injuries like fractured ribs, the alternative- doing nothing at all is far worse. In emergencies, what matters most is that you take action, and with practice, your technique can improve greatly.

Knowing What Is the Proper Depth of Compressions

Understanding what is the proper depth of compressions is essential for anyone who may encounter a situation where CPR is required. If you’re a healthcare worker or a concerned bystander, knowing how to perform chest compressions can save lives.

It’s always good to take CPR courses with hands-on practice. They can refine your skills and boost your confidence.
