Comparative Study
Beyond ventricular fibrillation analysis: comprehensivewaveform analysis for all cardiac rhythms occurring duringresuscitation.
To propose a method which analyses the electrocardiogram (ECG) waveform of any cardiac rhythm occurring during resuscitation and computes the probability of that rhythm converting into another with better prognosis (Pdes). ⋯ A method for continuous ECG waveform analysis covering all cardiac rhythms during resuscitation has been proposed. This methodology can be further developed to be used in retrospective studies of CPR techniques, and, in the future, for potentially monitoring in real time the probability of survival of patients being resuscitated.

Observational Study
Outcome of out-of-hospital cardiac arrests in Beijing, China.
The purpose of this study was to assess the outcome of out-of-hospital cardiac arrests (OHCAs) in Beijing, China. ⋯ In the urban areas of Beijing with EMS services, survival rate after OHCA was unsatisfactory. Improvements are required in every link of the 'chain of survival'.

Comparative Study
Local lay rescuers with AEDs, alerted by text messages, contribute to early defibrillation in a Dutch out-of-hospital cardiac arrest dispatch system.
Public access defibrillation rarely reaches out-of-hospital cardiac arrest (OHCA) patients in residential areas. We developed a text message (TM) alert system, dispatching local lay rescuers (TM-responders). We analyzed the functioning of this system, focusing on response times and early defibrillation in relation to other responders. ⋯ A TM-alert system that includes local lay rescuers and AEDs contributes to earlier defibrillation in OHCA, particularly in residential areas.

Comparative Study
Is enteral feeding tolerated during therapeutic hypothermia?
To determine whether patients undergoing therapeutic hypothermia following cardiac arrest tolerate early enteral nutrition. ⋯ Patients undergoing therapeutic hypothermia following cardiac arrest may be able to tolerate a substantial proportion of their daily nutritional requirements. It is possible that routine use of prokinetic drugs during this period may increase the success of feed delivery enterally and this could usefully be explored.

The rapid response system (RRS) has been widely implemented in the US. Despite efforts to encourage activation of the RRS, adherence to activation criteria remains suboptimal. Barriers to adherence to RRS activation criteria remains poorly understood. ⋯ Adherence to activation of RRT based on the six criteria measured is low. As familiarity with, agreement with, and perceived benefit of the RRS activating criteria rise, self-reported adherence rates increase, with familiarity having the greatest impact. These results can be used to develop tailored interventions to increase adherence to RRT activation in health care institutions.
