<p>A heart compression simulation device featuring a base; a resistance means disposed on the base; and an actuator operatively connected to the resistance means. The actuator can move between at least a starting position wherein the actuator is positioned at a starting position above the base and an end position wherein the actuator is pushed down near or contacting the base. The actuator is biased in the starting position caused by the resistance means. A tear effect providing mechanism provides resistance when moving the actuator from the starting position to the end position a first time. A lock-out mechanism is adapted to disengage the tear effect providing mechanism after the actuator has been moved from the starting position to the end position such that subsequent movements of the actuator between the starting position and the end position are not hindered by the tear effect providing mechanism.</p>
