Rigid Carry Case stores one ZOLL Compact Rescue System or Utility Rescue System so you can easily store it in work trucks or take it with you on-the-go. Each kit includes supplies to manage severe bleeding, airway complications, hypothermia, and more. The supplies in each kit pair with the Mobilize Rescue app (Compact kit includes a multi-user license; Utility kit includes an individual user license). Any user with the Mobilize Rescue app installed on their smartphone can help provide care in an emergency by simply following the interactive, real-time treatment instructions given by the app. Neither kit is included.
