Randomized Controlled Trial Comparative Study
Quality of CPR performed by trained bystanders with optimized pre-arrival instructions.
Telephone-CPR (T-CPR) can increase initiation of bystander CPR. We wanted to study if quality oriented continuous T-CPR would improve CPR performance vs. standard T-CPR. ⋯ In our simulated scenario with CPR trained lay rescuers, experimental continuous T-CPR gave better chest compression rate and less hands-off time during CPR, but resulted in delayed time to first chest compression compared to standard T-CPR instructions.

In advanced life support (ALS), time-cycled "loops" of chest compressions form the basis of action. However, the provider must compromise between interrupting compressions and detecting a change in cardiac rhythm. An "optimal" loop duration would best balance these choices. The current international CPR guidelines recommend 2-min loop durations. The aim of this study was to investigate the "optimal" loop duration in patients with initial asystole or pulseless electrical activity (PEA). ⋯ The "optimal" first loop duration may be 4 min in initial PEA and 6-8 min in initial asystole. If secondary PEA/asystole is encountered, 2-min loop duration seems appropriate.

Bystander cardiopulmonary resuscitation (CPR) is a vital link in the chain of survival for out-of-hospital cardiac arrest (OHCA); however, there are racial/ethnic disparities in the provision of bystander CPR. Approximately 32% of Hispanics perform CPR when confronted with cardiac arrest, whereas approximately 41% of non-Hispanics perform CPR. Public education, via the Internet, may be critical in improving the performance of bystander CPR among Hispanics. The objective of this study was to evaluate the availability and quality of CPR-related literature for primary Spanish-speaking individuals on the Internet. ⋯ A small proportion of internet resources have high quality CPR education for a Spanish-speaking population. More emphasis should be placed on improving the quality of educational resources available on the Internet for Spanish-speaking populations, and with particular emphasis on current basic life support recommendations.

In Japan, ambulance staffing for cardiac arrest responses consists of a 3-person unit with at least one emergency life-saving technician (ELST). Recently, the number of ELSTs on ambulances has increased since it is believed that this improves the quality of on-scene care leading to better outcomes from out-of-hospital cardiac arrest (OHCA). The objective of this study was to evaluate the association between the number of on-scene ELSTs and OHCA outcome. ⋯ Compared with the one on-scene ELST group, the three on-scene ELST group was associated with the improved one-month survival with favorable neurological outcome from OHCA in Osaka City.

Observational Study
First quantitative analysis of cardiopulmonary resuscitation quality during in-hospital cardiac arrests of young children.
The objective of this study is to report, for the first time, quantitative data on CPR quality during the resuscitation of children under 8 years of age. We hypothesized that the CPR performed would often not achieve 2010 Pediatric Basic Life Support (BLS) Guidelines, but would improve with the addition of audiovisual feedback. ⋯ In-hospital pediatric CPR often does not meet 2010 Pediatric BLS Guidelines, but compliance is better when audiovisual feedback is provided to rescuers.
