1. A method of cardiopulmonary resuscitation feedback, the method comprising:

  • determining a magnitude of a force applied to a cardiopulmonary resuscitation (CPR) feedback device;

    in response to determining the magnitude of the force exceeds a predetermined threshold;

    using at least one magnetometer to acquire three-dimensional (3D) spatial orientation data of the force;

    determining angular orientation and direction of the force in three-dimensional space based on the spatial orientation data; and

    one of wirelessly or through wired communication communicating the determined angular orientation and direction.
