1. A method for determining a depth and rate of cardiopulmonary resuscitation compressions, the method comprising the steps of:
providing a computer, a stationary feature, a data-generation device, and an article;
configuring the computer to receive data from the data-generation device;
locating the data-generation device to view the stationary feature and the article;
locating a person in cardiac distress lying on a surface;
configuring a Z axis as a direction orthogonal to the surface;
configuring the stationary feature as a fixed reference;
configuring the article to be movable with a chest of the person in cardiac distress;
configuring each of a plurality of coordinate systems to measure distance on the Z axis;
configuring the data-generation device to be a frame of reference in the plurality of coordinate systems;
viewing the article and the stationary feature with the data-generation device to generate the data sent to the computer; and
operating the computer to perform a calculation of a movement of the article along the Z axis over time relative to the stationary feature, said calculation utilizing the computer to rotate, scale, and translate travel measurements between the plurality of coordinate systems, said calculation comprising a determination of a difference between a first distance and a second distance, said first distance defined by a first space between the data-generation device and the stationary feature on the Z axis, said second distance defined by a second space between the article and the data-generation device on the Z axis.
