com·pres·sion

(kom-presh'ŭn),
A squeezing together; the exertion of pressure on a body in such a way as to tend to increase its density; the decrease in a dimension of a body under the action of two external forces directed toward one another in the same straight line.

In this prospective study, we randomized providers to provide conventional provider-driven CPR or CPR guided by an audio-visual feedback accelerometer to determine if there is a difference in the quality of the five critical components of CPR (chest compression depth, chest compression rate, chest recoil, excessive ventilation, and percent chest compression fraction (CCF%)) when applied in simulated cardiac arrest with in-hospital providers in the ED.
