First Claim
Patent Images
1. A method comprising:
- at a computing device of a cardiopulmonary resuscitation (CPR) feedback system;
obtaining measurement data from one or more sensors in the CPR feedback system;
determining orientation data in three-dimension (3D) space based on the measurement data;
calculating post compression information by applying a post compression algorithm to the orientation data in the 3D space, wherein the post compression algorithm calculates a compression displacement estimate invariant to a body orientation and a compression rotation, and wherein the post compression algorithm projects three-axis global referenced position data to a compression direction; and
presenting the post compression information on a display device of the CPR feedback system.
