Q: What is the band made of?
A: Latex Free silicone rubber
Q: Are batteries included?
A: Yes, but remove the safety tab before use. See instruction manual to access battery compartment.
Q: Can I clean my CRM?
A: Yes. We recommend simply wiping the product with an alcohol wipe. Because the wristband is made of silicone, using bleach products may be too harsh.
Q: I’m doing compressions properly but the light won’t turn green?
A: The Practi-CRM®is a precisely calibrated instructional aid. Instructors who have initially reported their CRM not functioning by not measuring CR properly often found it was indeed user error. Instructors whose common practice was to use a metronome found the CRM to perform accurately. Also, when the CRM is worn on the wrist, it is important that your arm is completely perpendicular to the manikin and not at an angle.
To check the accuracy of the CRM, you can google “metronome” and apply compressions at the set metronome rate.
