A chest compression feedback device is a medically useful gadget that provides immediate information to the rescuer on the efficiency of his/her chest compression activity during CPR. It usually records the compression rate, depth, and rebounding of the chest while doing CPR, and gives the rescuer some information about it through pictures or sounds. In this blog, you’ll learn what does a chest compression feedback device monitor in detail.

CPR stands for cardiopulmonary resuscitation; it is an emergency life-saving procedure performed when breathing and heart have stopped. CPR can also assist in preserving normal blood circulation into the brain and other body parts until emergency services return to normal heart functioning.

Cardiac resuscitation must be high-quality CPR for the patient to survive. According to AHA guidelines, Adults must receive chest compression at a speed of between one hundred and twelve chest compressions per minute (cpm) and two inches deep (5 cm). The intercostal compressions should be done to have a full chest expiration between every two compressions.

Benefits of a Chest compression feedback device:

Every second is crucial in the event of cardiac arrest. CPR is one of these emergency lifesaving procedures whose main application is to keep air flowing into the lungs till definitive medical care is arrived. However, chest compression feedback devices are crucial in ensuring that CPR is done correctly and effectively since the quality of CPR determines effectiveness.

One should therefore perform at least one hundred or slightly more than one hundred compressions per minute with complete chest recoil in between each compression and compressing with enough depth of about two inches or five centimeters on an adult. It is important to meet these criteria to sustain sufficient blood supply to vital organs, especially the brain, and enhance the possibility of survival.

The real-time chest compression feedback devices give information regarding the effectiveness of the chest compressions done by the rescuers at the same time. For example, most of these devices provide compression rate, depth, and recoil by using various sensors such as accelerometers, load cells, and pressure sensors. A processor analyses this data and converts it to visual and/or audio messages that direct the rescuer toward appropriate CPR skills.

Advantages of Using Chest Compression Devices

The advantages of using chest compression devices are numerous ensuring high-quality CPR and enhancing the survival rate for patients. These benefits include:

  • Enhanced Compression Rate Compliance: Chest compression feedback devices keep the rescuer to perform compression of the chest with the desired frequency (100-120 cpm) thus assuring blood flow.
  • Improved Compression Depth: These devices offer real-time feedback of compression depth which in turn helps rescuers deliver adequate blood flow during CPR.
  • Optimized Chest Recoil: The blood must be allowed to fill up back into the heart chambers for every beat which requires complete chest recoil. The use of chest compression feedback devices assists rescuers in attaining full recoil and effective flow of blood via the circulatory system to ensure survival among victims.
  • Reduced Hands-off Time: In CPR, hands-off time is referred to as intervals where no compression is done. Chest compression feedback devices promote persistent compressions, reducing interruption and assuring optimum blood circulation.
  • Enhanced Confidence and Skills: Rescuers can apply chest compression accurately because of chest compression feedback devices’ real-time guidance.

Chest compression feedback devices do not only improve cardiopulmonary resuscitation technique but also result in better patient results. Chest compression feedback devices have been proven beneficial according to various studies where survival rates of cardiac arrest patients have significantly increased.

Research conducted in the year 2019 and published in the Journal of the American Heart Association indicates that the use of CCFDs resulted in 35% fewer deaths in CPR-trained patients suffering from OHCA.

Similarly, a 2020 study published in Circulation: A study conducted by the Journal of Cardiovascular Quality and Outcomes showed that there is a 24 percent improvement in survival to hospital discharge with the use of chest compression feedback devices.

The key features of the Chest compression feedback device:

The key features include:

Compression Rate Monitoring:

The devices continuously monitor whether the rescuers are delivering chest compressions at a rate of 100-120 cpm and give immediate feedback.

Compression Depth Measurement:

The chest compression feedback devices are calibrated to precisely measure the depths of chest compressions which must be delivered at an average of two inches for adult rescues.

Chest Recoil Assessment:

These devices take readings at every compression to ensure that there is enough time for the cardiac chamber to fill up with blood before the next compression.

Hands-off Time Detection:

The chest compression feedback devices are designed to provide a warning to the rescuer when there is a pause in the compression of the chest minimize hand-off, and increase the rate of blood flow.

Visual and Auditory Cues:

These devices give visual or audible cues like light bars or beeps to rescue inappropriate compression rate, depth, and recoil.

User-Friendly Interface:

The chest compression feedback devices have user-friendly operating interfaces that are quick and easy to learn, thereby reducing the learning curves of rescuers.

Portability and Durability:

They are small in size and can easily be carried along or stored anywhere due to their portability. The equipment is also built to face the challenges encountered in such emergencies.

Data Storage and Connectivity:

The latest chest compression feedback devices also come with data recorder capabilities that are used in analyzing how well CPR was performed. Some devices may also connect to smartphones or other connected objects used in data sharing and remote monitoring.

The effects of trauma exposure on rescuers’ performance and patient outcomes

Chest compression feedback devices have an influence that goes beyond measuring and monitoring CPR factors. These are their real-time feedbacks and guidances that play a key role in shaping rescuer performance and outcomes of patients. Studies have consistently demonstrated that the use of chest compression feedback devices leads to:

Improved Compression Rate Compliance:

Rescue personnel with chest compression feedback devices usually manage to reach 100-120 CPM, which is the guideline-recommended.

Enhanced Compression Depth:

These devices provide feedback to rescuers, which enables them to perform compressions in sufficient depth at the right depth resulting in enough blood circulation.

Optimized Chest Recoil:

Chest compression feedback devices give guidance that stimulates full chest recoil and therefore efficient blood flow.

Reduced Hands-off Time:

These devices provide continuous compressions with minimal pauses improving blood flow.

Increased Rescuer Confidence:

Real-time feedback boosts rescue workers’ confidence to do perfect rescues by making more accurate decisions on giving CPR.

The majority of CCFDs usually implement several sensors that are utilized for the same purpose. These sensors may include:

Accelerometers:

Employing accelerometers measures the chest movement. This data determines the compression rate and depth.

Load cells:

The load cells ensure that they measure the force on the chest of the patients during compressions. This data is necessary for defining the compression depth.

Pressure sensors:

The pressure sensors record the amount of pressure in the chest throughout the compressions. One can employ the information for measuring the depth of compression and recoil.

The processor receives the sensor output data and processes it, then responds to the searcher. These include either visual or auditory cues such as feedback. A light could turn green once the rate of compression was appropriate. While turning red if the rate was not adequate. Additionally, may include a beeping sound when the compressing depth is either too shallow or too deep.

CCFDs typically monitor the following CPR parameters:

Compression rate:

The compression rate refers to chest compressions delivered during a minute. For adults, 100-120 compressions per minute is recommended.

Compression depth:

It is the depth of chest compression, also known as the compression depth. It is recommended to compress two inches (5 centimeters) in adults.

Recoil:

It means how much enlargement takes place in the chest following every period of contraction. Recoil also plays a significant role in ensuring the heart takes time to fill up the blood before another compressive wave.

Moreover, some of the CCFDs might look at other factors related to CPR delivery. Including the number of minutes the first responder stays without compressing the chest. Another is how the rescuer properly places their hands over the chest.
