Observational Study
Survival after Public Access Defibrillation in Stockholm, Sweden - A striking success.
In Stockholm, a first responder system and a Public Access Defibrillation (PAD) program has been implemented. Additionally, the number of "unregulated" public Automated External Defibrillators (AEDs) sold "over-the-counter" has increased. The aim of this study was to evaluate the impact on survival from different defibrillation strategies in cases of out-of-hospital cardiac arrest (OHCA) available for PAD. ⋯ In OHCAs available for PAD, 70% of patients survived if a public AED was used. Both the structured AED program as well as the spread of unregulated AEDs was associated with very high survival rates, but the structured approach was more efficient in relation to the number of AEDs used.

Observational Study
Hemodynamic targets during therapeutic hypothermia after cardiac arrest: A prospective observational study.
In analogy with sepsis, current post-cardiac arrest (CA) guidelines recommend to target mean arterial pressure (MAP) above 65 mmHg and SVO2 above 70%. This is unsupported by mortality or cerebral perfusion data. The aim of this study was to explore the associations between MAP, SVO2, cerebral oxygenation and survival. ⋯ we showed that a MAP range between 76-86 mmHg and SVO2 range between 67% and 72% were associated with maximal survival. Optimal cerebral saturation was achieved with a MAP between 87-101 mmHg and a SVO2 between 70% and 75%. Prospective interventional studies are needed to investigate whether forcing MAP and SVO2 in the suggested range with additional pharmacological support would improve outcome.

Observational Study
Videographic assessment of cardiopulmonary resuscitation quality in the pediatric emergency department.
To describe the adherence to guidelines for CPR in a tertiary pediatric emergency department (ED) where resuscitations are reviewed by videorecording. ⋯ CPR in a tertiary pediatric ED frequently met recommended parameters for compression rate, pause duration, and compression fraction. Hyperventilation and failure of C:V coordination were very common. Future studies should focus on the impact of training methods on CPR performance as documented by videorecording.

To determine the effectiveness of ventilations in bystander cardiopulmonary resuscitation (BCPR) and to identify the factors associated with ventilation-only BCPR. ⋯ Ventilation is a significant component of BCPR, but alone is less effective than compression in improving neurologically favourable survival after OHCAs.

The 2010 neonatal resuscitation program (NRP) guidelines incorporate ventilation corrective steps (using the mnemonic--MRSOPA) into the resuscitation algorithm. The perception of neonatal providers, time taken to perform these maneuvers or the effectiveness of these additional steps has not been evaluated. ⋯ Effective ventilation of the lungs with corrective steps using a mask is important in most cases of neonatal resuscitation. Neonatal resuscitators prefer early endotracheal intubation and initiation of chest compressions in the presence of asystolic cardiac arrest. Corrective ventilation steps can potentially postpone initiation of chest compressions and may delay return of spontaneous circulation in the presence of severe cardiovascular compromise.
