During chest compressions of a victim of cardiac arrest, the relative amount of time that the chest is compressed compared to the time that the chest is allowed to recoil to its fully inflated position. A cycle of 50% occurs when chest compression equals chest recoil.

The duty cycles of these PWM are proportional to entered speed.
The question was "is that duty cycle representative?" Engineers didn't know, and so began instrumenting test vehicles to measure real loads and develop more appropriate duty cycles.
