duty cycle

the percentage of time that ultrasound is being generated (pulse duration) over one pulse period. Also called duty factor, mark:space ratio.

(ti:ttot) (dū'tē sī'kĕl)
The ratio of inspiratory (ti) time to total-breathing-cycle time (ttot).

duty cycle

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.
