Proper CPR Hand Placement Cardiopulmonary resuscitation (CPR) is a critical life-saving technique used when someone’s heart stops beating. It helps maintain blood circulation to vital organs until emergency medical services (EMS) arrive. One of the most essential components of CPR is chest compressions, and understanding the correct hand placement is crucial for both effectiveness and safety.
Proper CPR hand placement ensures that the chest compressions are performed in a way that delivers the right amount of pressure to the heart without causing additional harm. In this article, we will explore the correct techniques for CPR hand placement and why it’s important to get it right.
Understanding CPR and Its Importance
Before diving into the specifics of hand placement, it’s helpful to understand what CPR entails and why it’s so vital. CPR is commonly administered when someone experiences cardiac arrest. During a cardiac arrest, the heart ceases to pump blood, which leads to a lack of oxygen in vital organs, especially the brain. Immediate action through CPR can dramatically increase the chances of survival until professional medical help is available.
While CPR consists of chest compressions, rescue breaths, and sometimes defibrillation, chest compressions are the most important part. These compressions help manually circulate blood, providing oxygen to the brain and other organs, which is why hand placement is crucial.
The Basics of CPR Hand Placement
In order to perform CPR effectively, it’s important to understand the precise location and positioning of the hands during chest compressions. Here are the main points to keep in mind:
Location:
The proper location for hand placement during CPR is the center of the chest, specifically the lower half of the breastbone (sternum). To locate this, you can start by placing two fingers just above the victim’s navel, then move upward until you feel the ribcage. The compression point should be directly over the sternum, between the nipples.
Hand Positioning:
Once you have found the correct location, the next step is to position your hands. Place the heel of one hand on the center of the chest, over the sternum. Then, place the heel of your other hand on top of the first, interlacing your fingers. Your arms should be straight, with your shoulders directly over your hands to ensure you are applying the appropriate amount of pressure.
Pressure and Depth:
For chest compressions to be effective, they must be deep enough to pump blood from the heart to the brain and other organs. Aim for a compression depth of about 2 inches (5 cm) for adults. The compressions should be hard and fast, with a rate of 100-120 compressions per minute. Remember that allowing the chest to fully recoil between compressions is just as important as applying adequate pressure.
Why Hand Placement Matters
Correct CPR hand placement is more than just an anatomical detail; it directly impacts the effectiveness of the compressions and the survival chances of the victim. Improper hand placement can lead to ineffective compressions, potentially causing harm, such as broken ribs or damage to internal organs.
For example, placing your hands too high on the chest can result in compressions that do not adequately compress the heart, while placing them too low can cause damage to the abdomen or fail to generate sufficient blood flow. Ensuring your hands are placed in the correct position optimizes the efficiency of each compression.
The Role of Hand Placement in Different Age Groups
While the fundamental principle of hand placement remains the same, there are slight variations in the technique depending on the age and size of the victim.
Adults:
For adult victims, use both hands, as previously described. The heel of your hand should be placed on the lower half of the sternum, and your fingers should be interlocked to allow for maximum pressure.
Children:
For children aged 1 to puberty, hand placement is somewhat similar to that of an adult, but you may use one hand if the child is small. For younger children, ensure the heel of your hand is placed over the lower half of the sternum, just as you would for an adult, but adjust the force depending on the child’s size and weight.
Infants:
For infants under 1 year old, the technique differs significantly. Instead of using both hands, you should use two fingers to perform compressions, placed just below the nipple line in the center of the chest. The depth of compressions for infants is shallower—about 1.5 inches (4 cm).
When to Perform Chest Compressions
It’s crucial to know when to begin chest compressions. CPR should be initiated immediately if you find someone unresponsive and not breathing, or if their breathing is abnormal. Here are the key indicators that CPR is needed:
The person is unresponsive when you try to wake them.
The person is not breathing, or they are only gasping.
There is no pulse detected (you can check for a pulse by feeling the carotid artery on the neck).
If the victim is not breathing and has no pulse, begin CPR immediately. If an Automated External Defibrillator (AED) is available, follow the device’s prompts.
Common Mistakes in CPR Hand Placement
Even with the best intentions, many people make mistakes when performing CPR. Understanding common errors can help ensure you provide the best care in an emergency.
Hands Too High or Low:
As previously mentioned, hand placement should be centered on the sternum, specifically over the lower half. Placing the hands too high can lead to ineffective compressions, while too low can damage the abdomen.
Fingers Not Raised:
When your hands are interlocked, your fingers should not be pressing down on the chest. If the fingers are touching the chest, it can interfere with the compression force and reduce the effectiveness of the compressions.
Too Much Pressure:
While applying firm pressure is essential, using excessive force can cause injury to the ribs or sternum. The correct depth of compression is around 2 inches for adults, but pushing too deeply can cause unnecessary harm.
Conclusion
Proper CPR hand placement is one of the most crucial factors in performing effective chest compressions during an emergency. Knowing where and how to position your hands can significantly increase the chances of survival for someone in cardiac arrest. Always make sure you’re applying the right amount of pressure and depth to maintain circulation and provide oxygen to the brain and organs.

FAQs
How deep should chest compressions be during CPR?
For adults, chest compressions should be about 2 inches deep (5 cm). For children, the depth should be about 1/3 of the chest’s depth, and for infants, it should be about 1.5 inches (4 cm).
Can CPR be performed with just one hand?
Yes, CPR can be performed with one hand for children, especially for smaller victims. However, for adults, both hands are typically required to provide enough force for effective chest compressions.
What should I do if I’m unsure about the correct hand placement?
If you’re unsure, try to remember that the hands should be positioned on the center of the chest, over the lower half of the breastbone. If you’re trained in CPR, this will come naturally. However, it’s always best to take a CPR course for hands-on practice.
How long should I continue CPR?
Continue performing CPR until emergency help arrives or the person starts to show signs of life, such as breathing or moving. If an AED is available, follow the prompts of the device while continuing CPR as needed.
Is CPR safe to perform if I’m not trained?
While CPR is best performed by someone trained, even untrained bystanders can help by doing chest compressions. If you’re not trained, performing chest compressions is better than doing nothing. As it can help maintain blood circulation until help arrives.
