CPR feedback devices have gained some popularity over recent years. There are several manufacturers and variations, but essentially all CPR feedback devices perform similar functions., They monitor rate - and many monitor depth of compressions to ensure that CPR delivery is consistent with AHA guidelines. The data can also be downloaded in order to assess interruptions and average depth during a code event.
These devices are not cheap. Laerdal, for instance, markets one for $895.
We looked at a few studies aimed at determining whether these devices improve CPR quality during actual cardiac arrests.
In a recent European study, of three different brands of feedback devices, the researchers found that none improved BLS quality during actual code events when compared to standard BLS without devices. Furthermore, placing the devices can cause delay in CPR, potentially creating harmful outcomes.
On the other hand, feedback device maker Laerdal quotes increased survival rates in New York City by over 10 percent after the devices were introduced there. However, these statistics were evaluated in a retrospective data analysis, and there may be other factors at play in increased survival rates during the time period.
Although the AHA advises CPR feedback devices for training purposes, ultimately, the jury is still out as to whether these devices are helpful in an actual code event, which is why the 2015 AHA guidelines state "It may be reasonable to use audiovisual feedback devices during CPR for real-time optimization of CPR performance." Note the equivocal nature of the sentence.
End Tidal Carbon Dioxide Measurement remains THE standard for monitoring CPR quality in patients with an advanced airway.

There has been an increase in local protocols for 911 dispatchers to be able to identify victims in need of CPR based on caller reports, and to coach bystanders in performing CPR until first responders arrive.
Studies show that victims who receive bystander CPR are twice as likely to survive as those who do not receive any bystander CPR until EMS arrives. In order to facilitate this change local emergency response dispatchers must be trained in recognition of arrest based on witness statements and training must take place on efficient ways to coach bystanders in CPR.
These changes began being implemented in the Seattle area in 1982, and have since been started in many communities around the country. That being said, the training and roll out of dispatcher coached CPR is far from universal across EMS systems, despite the evidence.
Another factor is that, although many communities state that they teach dispatcher assisted CPR, few may teach dispatchers to be aggressive in questioning that will lead to coaching the bystander into doing so. Dispatchers also need to know how to give clear, simple instructions, and how to cut through extraneous verbage in order to get the job done.
This addresses the core public health function of assurance, with the linking of the population to care and assurance of a competent public health (dispatcher) workforce.
Two determinants of public health are at play here- the healthcare realm, in which people are linked to appropriate care, and the social environment, where community members can render assistance to those in need with on the spot coaching.
These changes were implemented based on a retrospective study of case results showing increased survival to discharge rates of victims of cardiac arrest when immediate bystander CPR was performed.

American Heart Association Heartsaver CPR courses are designed for the general public, and highlight the steps to CPR and AED use performed by a single lay rescuer.
Some of the things taught in a Heartsaver CPR course include:
AHA's Basic Life Support for Healthcare Providers is a course designed specifically for healthcare workers, who are frequently in an environment that requires a coordinated team approach to CPR.
BLS courses cover all of the Heartsaver teaching points, but add:
