DUTY CYCLE OPTIMIZATION IN CARDIOPULMONARY RESUSCITATION SYSTEMS

原文（中文）

CPR systems and/or CPR devices that are configured to operate in association with a particular duty cycle are disclosed. An example mechanical chest compression device includes a processor(s) and a chest compressing mechanism configured to be disposed on a chest of a subject and to move for administering chest compressions to the subject. The processor(s) is configured to cause the chest compressing mechanism to move for administering the chest compressions to the subject over a series of compression-decompression cycles, wherein a compression-decompression cycle of the series of compression-decompression cycles includes a compression phase that is shorter than a decompression phase. The processor(s) is further configured to determine, during the compression phase, that a criterion is satisfied, and to cause the chest compressing mechanism to transition to movement that corresponds to the decompression phase in response to determining that the criterion is satisfied.
