Affirmation of the importance of precision in fundamentals of resuscitation practices with improving neurologically intact survival from sudden cardiac arrest, correlated with both measurements of resuscitation metrics generically and recently further refined metric parameters specifically.
Quality of baseline cardiopulmonary resuscitation (CPR) in historic intervention trials may not be 'high quality' as once assumed. Optimal chest compression rates are within the narrow spectrum of 106-108/min for adults. Optimal ventilation rates remain within the 8-10/min range.
Although traditional CPR teaching of 'hard and fast' chest compressions has promoted a relatively easy to remember directive, the reality is that laypersons and medical professionals alike may unwittingly provide markedly suboptimal chest compression depths and rates. Prior resuscitation studies that focused upon airway adjuncts, defibrillation strategies, and/or pharmaceutical interventions that did not simultaneously gauge the underlying CPR chest compression rates, chest compression fraction of time, and ventilation rates should be cautiously interpreted in light of discovery that assumption of 'high-quality CPR' without measurement of the metrics of such is likely a faulty assumption.
随着心肺复苏术（CPR）基本操作中对精确性的重视程度不断提高，心搏骤停后神经功能完整存活率得到提高，复苏指标的测量方法（广义）和最近专门细化的指标参数（狭义）都得到了相应的改进。
历史干预试验中基础 CPR 的质量可能不像以前认为的那样“高质量”。成人最佳的胸外按压频率在 106-108 次/分的狭窄范围内。最佳通气频率仍在 8-10 次/分的范围内。
尽管传统的 CPR 教学强调“有力且快速”的胸外按压，这一简单易记的指令，但实际上，非专业人员和专业医疗人员可能会在无意中提供明显深度和频率不足的胸外按压。先前的复苏研究侧重于气道辅助、除颤策略和/或药物干预，而没有同时评估潜在的 CPR 胸外按压频率、胸外按压时间比例和通气率。鉴于发现假设在没有测量这些指标的情况下存在“高质量 CPR”，那么之前未测量这些指标的复苏研究结果需要谨慎解读。
