5 Reasons Why Real-Time Feedback Can Make the Difference

The longer your pre-shock pauses and the shallower your chest compressions, the less likely you will be to achieve defibrillation success.This, of course, applies to a shockable rhythm, VF (ventricular fibrillation) and VT (pulseless ventricular tachycardia).

This finding comes from a study which concluded that each 5 mm increase in compression depth and each 5 second decrease in pre-shock pause shows a doubled increase in the likelihood of shock success after adjusting for arrest location, age, sex and time to shock.3 However, today’s technology, capable of sensing compression rate and depth, has shown that frequent pauses and shallow compression depth are common in clinical practice.³

Real-time feedbackcan be used to moderate those factors by guiding a CPR provider at the time those factors start to play their destructive role.

根据AHA在2006年的一项研究，尽管有建议，但救援人员通常不会深深地压缩胸部4。研究不仅证明了每个患者的胸部抗性都不同，而且还证实，随着心肺复苏期间执行的压缩次数的增加，胸部僵硬显着降低。⁴In 2006, there was no upper limit on compression depth. Post - 2015 AHA Guidelines, there is: 2-2.4 inches for adults and adolescents.

鉴于实时反馈现在是一项容易获得的技术，因此实现了正确的压缩深度并为除颤成功奠定了基础，这不是一个猜测游戏。如果您或您的同事曾经觉得这是一款猜测游戏，那么将实时反馈引入您的程序可以帮助消除这种感觉。

You've likely heard or used the phrase, "I'm not in the loop." This expression comes from the U.S. Air Force concept of a "control loop" known as the OODA loop. When a pilot says he or she is "out of the loop," it means the pilot can no longer observe, orient, decide, and/or act, when flying on autopilot, for example.

Practitioner or pilot, both are high stakes roles in which autonomy and ownership are critical to success. Real-time feedback by its nature gives practitioners little choice but to be engaged in the OODA loop, which improves situational awareness, team performance, and individual attention to detail during CPR.

AHA建议每个EMS系统，医院和其他专业救援人员计划都应具有持续的CPR CQI（持续质量改进）计划，向董事，经理和提供者提供反馈。

这种计划使提供商有机会专注于具有长期目标的长期愿景。最大程度地提高质量CPR的五个关键指标的性能不仅对每个患者案件至关重要，而且对组织的整体成功和ESPRIT至关重要。

Real-time feedback可以帮助您为除颤成功，优化的血液动力学，最佳压缩，提供者所有权以及最重要的是持续改进而创造更好的条件。实时反馈可以使您有能力面对您的性能当前错误的方法，同时也可以保证您可以并且将有所改善。
