Simple CPR-feedback for every first responder

SimCPR®Trainer with free App is a new revolutionary training tool. It also shows you how our simple SimCPR®-feedback works.

SimCPR®Pro (available Q4 2021) makes CPR more effective.
Simple affordable feedback optimizes chest compressions of every first responders.


SimCPR®Trainer is used by students during CPR-training and meets the requirements of the American Heart Association (AHA) for feedback devices. It provides visual feedback on rate and correct compression/decompression during CPR training.

In combination with the free SimCPR®Trainer App also audio feedback is added and students can test their skills scores on depth, rate and CPR-pauses.

With our trainer students also learn how to use our medical device for CPR-feedback the SimCPR®Pro (available Q4 2021). 

Please feel free to contact us.


How does SimCPR®Pro work?

SimCPR®Pro (available Q4 2021) supports first-responders to perform effective chest compressions according to the international CPR-guidelines.

The smart SimCPR®-accelerometer accurately calculates the distance between compression and decompression. 

After switching the device on, the flashing red LED indicates a correct tempo of chest compressions (110/min).

As long as compression-decompression is less than 5 cm/2 inches, the red LED will continue flashing. This means compressions are not deep enough and/or the recoil of the victim’s chest is not complete.

As soon as compression-decompression of the chest is more than 5 cm/2 inches, the green LED will flash (110/min). 

This form of feedback improves the quality of CPR, even by healthcare professionals (Resuscitation 2019).
