Watch-type heart rate monitor Practi-CRdM

The Practi-CRdM Compression Rate and Depth Monitor is a useful tool for measuring the rate and depth compression of CPR while practicing on a manikin. To use the CRdM, simply wear it on your wrist while practicing CPR on a manikin. The device will “beep” when compression depth is outside the optimal range of 5-6cm (2”-2.3”). Additionally, the CRdM’s diode will be green when compression rate is between 100 and 120 cpm, and red when compressions fall below 100 cpm or exceed 120 cpm. This feature enables 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) Features: Works 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 already own, even if those manikins do not offer compression rate and/or depth monitoring. The AHA required these key elements by the end of January, 2019 (see AHA Requirement Tab below).
