An accurate perception of time is critical for responders to cardiac arrests and other medical emergencies. Interventions such as medications or defibrillation are meant to be given at particular times. External chest compressions and bag-valve mask ventilations should be done at a particular rate. Accurate timing of the length of pulselessness may have implications for post-emergency management. Additionally, reported timing of pulselessness may alter clinicians' perception of the patient's chances for neurological recovery. Prior research indicates that stressful situations may impair subjects' time perception. It is hypothesized that this is true for responders to medical emergencies. Although there are many competing factors, responders to medical emergencies most likely feel that time passes more slowly than it actually does. This could have important implications for patient management both during and after medical emergencies.
对心脏骤停和其他医疗紧急情况的响应者而言，准确感知时间至关重要。诸如给药或除颤等干预措施应在特定时间进行。胸外按压和球囊面罩通气应以特定速率进行。无脉持续时间的准确计时可能对紧急情况后的管理有影响。此外，报告的无脉持续时间可能会改变临床医生对患者神经功能恢复几率的认知。先前的研究表明，压力情境可能会损害受试者的时间感知。据推测，医疗紧急情况的响应者也是如此。尽管存在许多相互竞争的因素，但医疗紧急情况的响应者很可能感觉时间过得比实际情况更慢。这可能对医疗紧急情况期间及之后的患者管理产生重要影响。
