Quantitative analysis of ventricular fibrillation (VF), such as amplitude spectral area (AMSA), predicts shock outcomes. However, there is no uniform definition of shock/cardiopulmonary resuscitation (CPR) success in out-of-hospital cardiac arrest (OHCA). The objective of this study is to investigate post-shock rhythm variations and the impact of shock/CPR success definition on the predictability of AMSA. ⋯ Post-shock rhythm is unstable in the first minute after the shock. The predictability of AMSA varies depending on the definition of shock/CPR success and performs best with the return of potentially perfusing rhythm endpoint for OHCA.

Observational Study
Characteristics of bystander cardiopulmonary resuscitation for paediatric out-of-hospital cardiac arrests: A national observational study from 2012 to 2014.
This study evaluated the associations between the provision of bystander cardiopulmonary resuscitation (BCPR) and both the relationship of bystanders with paediatric out-of-hospital cardiac arrest (OHCA) victims and the community educational level. ⋯ In paediatric OHCA cases, family members were more likely than strangers to perform BCPR except in communities with the lowest educational level.

Relationship between cardiopulmonary arrest and resuscitation (CPR) durations and survival after out-of-hospital cardiac arrest (OHCA) remain unclear. Our primary aim was to determine the association between survival without neurologic sequelae and cardiac arrest intervals in the setting of witnessed OHCA. ⋯ NF duration must be considered in determining CPR duration in OHCA patients. The knowledge of (NF, LF) curves as function of age, initial rhythm, location of cardiac arrest or gender may aid in decision-making vis-à-vis the termination of CPR or employment of advanced techniques.

Use of automated external defibrillators (AEDs) has been recommended for pediatric out-of-hospital cardiac arrest (OHCA). However, there are no conclusive studies that elucidated the effectiveness of public-access defibrillation (PAD) in children. ⋯ PAD was associated with an increased chance of neurologically favorable survival in pediatric OHCA (aged 1-17 years) who received bystander CPR, except for in cases of unwitnessed or non-cardiac etiology.
