In conjunction with AED Plus, CPR-D padz provide CPR coaching and feedback – critical information unavailable with any other AED system. A sensor on the CPR-D padz tracks the rescuer’s compression depth and rate as soon as CPR begins. During CPR, audio and visual cues help prevent the two most common errors: inadequate depth and inadequate rate. Voice prompts like “press harder” or “good compression” are delivered while its adaptive metronome leads the rescuer to the recommended 100 compressions-per-minute rate. CPR-D padz come complete with rescue essentials including a barrier mask, a razor, scissors, disposable glove and a towelette. CPR-D padz provide an unsurpassed four-year shelf-life and its unique tamper-evident seal provides the user the important lot code and expiration information without the need to open the AED Plus’ cover. The CPR-D padz combines state-of-the-art storage, easy application, and useful clinical tools into the best therapy delivery system available today. The CPR-d Padz by Zoll are sterile for 4 years and have a 4 year shelf life. Package includes (1) One Piece Pad and Rescue Pack.
