WLCRdM Practi-CRdM CPR Compression Rate & Depth Wrist Monitor

Part # WLCRdM Practi-CRdM CPR Compression Rate & Depth Wrist Monitor.

The Practi-CRdM Compression Rate and Depth Monitor is designed to measure compression rate and depth when practicing CPR on a manikin. The student wears the CRdM on their wrist.  It will provide an audible “beep” when compression depth is not within the range of 5-6cm (2”-2.3”).   The diode will illuminate green when compression rate is between 100 and 120 cpm. On the other hand, a diode illuminates red when compressions are below 100 cpm or above 120 cpm. Therefore, this allows users to self-check their timing.


Thanks to feedback and reviews from our customers on the first iteration of the Practi-CRdM, we have made key enhancements:

       First,  we increased the feedback beep(s) volume.
       Next,  we extended the auto-shutoff time.

This allows more time between compression activity and the automatic shut-off feature (the Practi-CRdM will shut off after 2 minutes of inactivity)

You may use the Practi-CRdM with any training manikin. The flexible wristband fits any size wrist. The rechargeable lithium battery lasts a minimum of 3-4 hours. The Practi-CRdM may be charged via USB port. Charging time is between 2-3 hours.


The Practi-CRdM provides an affordable solution that helps  training centers protect their investment in the manikins they own which do not offer compression rate and/or depth monitoring. The AHA required these key elements by the end of January, 2019.

Comes with a 1 year warranty.
