what does a chest compression feedback device monitor: Know about it

In the event of a cardiac arrest, the lifesaving operation known as cardiopulmonary resuscitation (CPR) consists of performing chest compressions. By maintaining blood flow to the brain and heart, chest compressions improve the chances of survival. Chest compression feedback device monitor are a lifesaving technique, but they can be challenging to conduct correctly and consistently, and it can be hard to discern if they’re working without adequate feedback. A chest compression feedback device can help medical professionals, first responders, and bystanders evaluate the efficacy of CPR. Real-time data on compression levels, velocity, and recoil are just some of the characteristics these tools may monitor. Let’s look at what a chest compression feedback device measures.

Compressive Pressure

One of the most crucial metrics a chest compression feedback device monitor can detect is the depth of chest compressions. The device might assess the depth of chest compressions performed on an adult and provide feedback on whether or not they are within the recommended range of 2-2.4 inches (5-6 cm). Compressions that are too deep can cause internal injuries or chest injuries, while compressions that are too shallow may not generate adequate blood flow.

Compression Rate

A chest compression feedback device monitor may also monitor the compression rate or the number of compressions conducted per minute, which is an advantageous signal. You should aim for a rate of 100 to 120 compressions per minute. If a device measures compression rates, it can show whether they are optimal. A too-slow or too-rapid compression rate might lead to inadequate filling of the heart chambers between compressions.

Positioning of the Hands

If the hands aren’t above the heart, chest compressions won’t help. When applying chest compression, the hand should be placed in the middle of the chest, between the nipples; the chest compression feedback device will indicate if this is not the case. Improper hand placement during compressions might lead to insufficient pressure being applied to the chest.

Disruption of Time

In CPR, the “interrupted time” refers to the pauses between chest compressions. When you’re aiming to improve blood flow, every little bit counts. Using the chest compression feedback device, medical personnel, first responders, or bystanders can learn how often compressions are interrupted.


It is essential to provide rescue breaths, or ventilations, to the person in cardiac arrest. The number of breaths given and the intervals between breaths can be relayed to the user via the chest compression feedback device. In addition, it can determine whether or not the patient’s age, size, and health condition warrant the current ventilation rate.

CPR: resuscitation percentage

To express the proportion of CPR time spent on chest compressions, the term “CPR fraction” is used. The CPR fraction can be tracked, and feedback on compression time is provided by a device placed on the chest.

Chest Compression Feedback Device Monitor Alternatives

While feedback devices for chest compressions are a fantastic approach to ensure proper technique during CPR, they may not always be accessible. In such cases, different methods of counting CPR chest compressions are available, including:

Visual Input

The visual input of watching the chest rise and fall with each compression is significant. This strategy helps achieve the optimal compression and recoil. But it might need to reveal honest details like compression speed and completion time.

Manual Control And Monitoring

Tracking blood flow manually during CPR entails feeling for a pulse and looking for other telltale indicators. This method may not provide specific information on chest compressions, but it can help evaluate the efficacy of CPR in general.

Audio Feedback And Reaction

Using a metronome or other sound-making equipment to provide a consistent beat during chest compressions is an example of audio feedback. This technique might assist in checking if the compression rate is within the recommended range of 100 to 120 per minute.

Simulation Instruction And Training

To perfect one’s CPR techniques, simulation training utilizes either a manikin or a computer. This method provides a realistic simulation of a cardiac arrest and allows medical professionals, first responders, or bystanders to practice CPR while receiving feedback from trainers or instructors.


Devices that provide feedback on chest compressions have been used beyond CPR instruction. Once you’ve practiced with the tool, the appropriate amount of effort for chest compressions should be evident. They are also helpful for teaching CPR to the elderly and people with disabilities, who may not be able to safely perform it on someone who has suffered a head injury from a fall on a hard surface like concrete or tile.
