Quality CPR matters
The trained rescuer knows that when faced with a sudden cardiac arrest patient, time and optimal therapy is critical for survival. Quality CPR combined with early defibrillation is essential to improve survival.1-3 Guidelines 4-5 provide direction on a number of parameters that define Quality CPR. However, the challenge for all emergency healthcare providers remains:

How can guidelines compliant CPR be delivered consistently throughout the whole chain of survival?

Patients Vary

Chest-depth-force-relationshipsThe 2010 Guidelines recommend compressing the patients’ chest at least 5 cm. Knowing when you have reached 5 cm is however difficult. As chest stiffness varies, some patients need much more compression force to meet the same guideline.This complicates matters even further. In fact, Tomlinson et al (2007) showed that patients’ chests require a compression force ranging from 10 - 55 kg force to reach the minimum compression depth. 6


How does CPRmeter™ work?
CPRmeter™ has two embedded sensors: one measuring acceleration and another measuring force. A sophisticated microprocessor continuously measures both of these parameters during each compression, and special algorithms convert the collected data into meaningful information.

The accelerometer measures the depth and rate of chest wall movement during each compression and converts it into distance travelled. The force sensor measures the force applied during CPR and is also used to detect whether the patient's chest is allowed to fully release between compressions. Feedback is provided if the responder is leaning during CPR. This helps the trained rescuer to deliver guidelines compliant chest compressions regardless of the chest stiffness of an individual patient.

Its rugged construction and excellent viewing angles, even in difficult environmental conditions, makes CPRmeter ideally suited to the chaos of the emergency situation.

Assuring quality
While survival rates from sudden cardiac arrest have remained virtually unchanged for 25 years, recent studies have shown that significant improvements in patient outcomes are possible when healthcare organisations implement systematic QA and QI initiatives.7-8

Using Laerdal’s latest generation of Q-CPR technology, the CPRmeter™ records and documents CPR performance. This opportunity to debrief events objectively is essential to facilitate team improvement and establish best practice to help improve patient outcomes.7-8

QreviewQ-CPR Quick Review
The opportunity for trained responders to immediately self-evaluate their CPR performance is both an empowering and motivating feature of the CPRmeter™. This can help reassure that optimal CPR has been delivered or highlight areas for improvement for discussion during the de-brief.

reviewQ-CPR Review
An optional Micro SD card can capture comprehensive CPR event statistics for in-depth evaluation and debriefing. A quick download into the Q-CPR Review software enables the user to:

- Create a graphical view of a CPR case for debriefing
- Create and print an individual CPR Report Card
- Compile CPR event statistics for multiple cases

Q-CPR Review software provides the foundation for a successful CPR quality improvement programme.


CPRmeter™ Improves CPR Skills Retention 9,10,11
CPR training for both ALS and BLS courses require demonstration of guidelines compliant CPR 12. Studies indicate that CPR skills decrease quickly following traditional CPR training 13,14,15. More frequent refresher training, more hands-on skills practice and reduced intervals of re-certification have been highlighted as methods to address this problem.16 A valuable solution for recommended low dose, high frequency refresher training, the CPRmeter™ used with a manikin can help the trainee to improve and maintain CPR skills, while helping the instructor to easily assess competence for re-certification.

The CPR meter helps to guide the trained provider to deliver quality CPR by providing dynamic realtime feedback on essential parameters of CPR.
