Role of Chest Compression Feedback Devices in CPR -PDF Guide

Chest Compression Feedback Devices in CPR

A chest compression feedback device is a piece of medical equipment designed to provide real-time feedback and guidance to healthcare professionals or bystanders performing chest compressions during cardiopulmonary resuscitation (CPR). These devices are used to ensure that chest compressions are administered with the appropriate depth, rate, and technique, which is crucial for effectively circulating blood and oxygen to the brain and vital organs in a person experiencing cardiac arrest.

What are the key features and functions of chest compression feedback devices?

Depth Monitoring: They measure and provide feedback on the depth of each chest compression to ensure it reaches the recommended depth (typically around 2 inches or 5 centimeters for adults).

Rate Monitoring: These devices monitor the rate at which chest compressions are delivered, ensuring that it falls within the recommended range (typically between 100 and 120 compressions per minute for adults).

Recoil Detection: Proper chest recoil between compressions is essential to allow for adequate blood flow during CPR. Feedback devices can alert the user if they are not allowing for full chest recoil.

Hand Positioning Guidance: Some devices offer guidance on proper hand placement to ensure that chest compressions are administered in the correct location on the chest.

Audible and Visual Feedback: Many chest compression feedback devices provide real-time feedback through audible tones or visual displays, indicating whether compressions are being performed correctly or if adjustments are needed.

Compression Fraction: They calculate and display the percentage of time during CPR that chest compressions are being administered, helping users maintain a high compression fraction for optimal CPR quality.

Data Recording: Some devices record CPR data for later review and debriefing, allowing healthcare providers to assess the quality of CPR performed during a resuscitation event.

Integration with Automated External Defibrillators (AEDs): In some cases, these devices are integrated with AEDs to provide comprehensive guidance during sudden cardiac arrest emergencies.


A chest compression feedback device, commonly used in cardiopulmonary resuscitation (CPR), is designed to monitor and provide feedback on the quality of chest compressions during the resuscitation of a person in cardiac arrest. These devices are often used in conjunction with automated external defibrillators (AEDs) or as standalone tools to improve the effectiveness of CPR.

What does a chest compression feedback device monitor?

Here are the main parameters and aspects that a chest compression feedback device typically monitors:

Compression Depth: It measures the depth of each chest compression. The American Heart Association (AHA) and other guidelines recommend compressions of at least 2 inches (5 centimeters) deep for adults.

Compression Rate: It monitors the rate at which chest compressions are being performed. The recommended compression rate for adults is typically between 100 and 120 compressions per minute.

Recoil: A critical aspect of CPR is allowing the chest to fully recoil between compressions. The device can detect if the chest is not fully recoiling after each compression.

Hand Position: Proper hand placement on the chest is crucial to ensure that compressions are effective. The device can provide feedback on hand placement.

Compression Fraction: This metric represents the percentage of time during CPR that chest compressions are being performed. A higher compression fraction indicates more effective CPR.

Rate and Depth Consistency: The device can provide feedback on the consistency of compression rate and depth to help maintain the quality of CPR over time.

Visual and Audible Feedback: Many chest compression feedback devices have visual displays or audible cues to guide the rescuer in real-time, indicating whether they should push harder, push softer, push faster, or slow down.

Real-time Data Recording: Some devices record data over the course of CPR, which can be useful for debriefing and reviewing the quality of CPR after the event.

These devices are valuable tools for healthcare providers and laypersons alike, as they help ensure that CPR is administered correctly and with the necessary quality to maximize the chances of survival for a person in cardiac arrest.

  4. The device helps by Freeing up hands and reducing chaos around the patient
  5. Devices also allows us to Calms down the scene and buying time to make decisions
  6. They Provide CPR guidance and data for feedback

Where do we require these devices?

The use of mechanical CPR devices may be considered in specific settings where the delivery of high-quality manual compressions may be challenging or dangerous for the provider, as long as rescuers strictly limit interruptions in CPR during deployment and removal of the device.”

Reference: AHA 2020 Guidelines. Circulation. 2020;142(suppl 2):S366–S468


The optimal timing for deploying a mechanical device during a cardiac arrest is uncertain, especially in patients who present with a shockable rhythm. The deployment process involves interrupting chest compressions, which can be detrimental if the pause is prolonged. It is recommended that the use of mechanical devices should only occur in systems that have quality assurance mechanisms in place to monitor and handle pauses associated with deployment.

Mechanical CPR devices may be helpful in certain circumstances as an additional treatment option, but there is not enough evidence to support their regular use.

Mechanical CPR: Who? When? How?


Chest compression feedback devices are used to improve the quality of CPR and increase the chances of survival for individuals in cardiac arrest. They are particularly valuable for ensuring that even untrained or less experienced individuals can deliver effective chest compressions when needed. These devices play a crucial role in promoting high-quality CPR and ultimately saving lives during cardiac emergencies.

Dry Granulation

Dry granulation is a powder agglomeration process used in the pharmaceutical industry to improve the flowability of powders by increasing the particle size (granules). This operation is achieved using a roller press, which can have different configurations and equipment designs.
In simple terms Granulation is the process in which primary powder particles are made to adhere to form larger multiparticle entities called granules.

Dry granulation Roller compactor

Dry Granulation Advantages & Limitations:

(Slugging of rollercompaction)
* Eliminates exposure to moisture and drying.
* Dusty procedure.

This is also called double compression or slugging method, this is valuable alternative to direct compression,
where the dose of drug is too high or to wet granulation when the drug is sensitive to heat, moisture or both.
This method is also used when other methods of granulation yield granules with poor flow or compression
properties, because there are less chances of segregation of drug and excipients.

* Not suitable for all compounds.
* Slow process.

Long processing time, a relatively high capital investment on heavy duty presses or compactors.


Steps involved in dry granulation process

I. Milling of drugs and excipients
II. Mixing of milled powders
III. Compression into large, hard tablets to make slug
IV. Screening of slugs
V. Mixing with lubricant and disintegrating agent
VI. Tablet compression


In dry granulation method the primary powder particles are aggregated at high pressure. There are two main processes – either a large tablet (known as slug) is produced in a heavy duty tableting press( known as slugging) or the powder is squeezed between two rollers to produce a sheet of material (roller compaction) . The two different types are illustrated in below:

Slugging process

how well a material may slug will depend on the below terms

  1. Compressibility or cohesiveness of the matter,
  2. Compression ratio of powder
  3. Density of the powder
  4. Machine type
  5. Punch and die size
  6. Slug thickness
  7. Speed of compression
  8. Pressure used to produce slug

Granulation by slugging is the process of compressing dry powder of tablet formulation with tablet press having die cavity large enough in diameter to fill quickly. The accuracy or condition of slug is not too important. Only sufficient pressure to compact the powder into uniform slugs should be used. Once slugs are produced they are reduced to appropriate granule size for final compression by screening and milling

Slugging (Old Method)Slugging (Old Method) • material to be granulized is first made into a large compressed mass or “slug” typically by way of a tablet press using large flat-faced too long.

Disadvantages of Slugging:

  1. single batch processing
  2. frequent maintenance changeover
  3. poor process control
  4. poor economies of scale
  5. low manufacturing output per hour
  6. excessive air and sound pollution,
  7. Increased use of storage containers,
  8. more energy and time required to produce

Roller compaction:

In a roller compactor material particles are consolidated and densified by passing the material between two high-pressure rollers. The densified material from a roller compactor is then reduced to a uniform granule size by milling.
Roller compaction dry granulation process is capable of handling a large amount of material in a short period of time. As a special subtype briquetting utilizes special designed compaction rolls which divides the compacted powder in pieces (briquettes).
For dry granulation the compaction force in extend and uniformity of distribution is essential in regard to uniformity of granules porosity to ensure uniform hardness and disintegration of the final product. Because of its advantages, roll compaction is being increasingly used as a granulation technique, but it is not a simple process and may involve many variables for example roll pressure, roll speed, horizontal/vertical feed screw speed, roller gap, screen size. These parameters need to be optimized depending on the materials and the type of equipment used in order to obtain products of desirable quality.

Pneumatic Dry Granulation:

The pneumatic dry granulation process is a new and patent pending technology. The granulation process is based on the
use of roller compaction with very low compaction force together with a proprietary air classification method. The method enables production of granules with extraordinary combination of flow ability and compressibility. The granules produced by Pneumatic Dry Granulation and tablets produced show fast disintegration properties, offering the potential for fast
release dosage forms, and Release time can be tailored to requirements.
PDG technology can achieve, high drug loading, even with difficult APIs and combinations along with Taste masking and Excellent stability
