Resuscitation

CPR quality is an important determinant of cardiac arrest outcome. Recent investigations have demonstrated that quality of clinical CPR is variable and often not in compliance with international consensus guidelines. The 2005 update of these guidelines included new recommendations for the measurement of resuscitation and CPR performance and the institution of measures to improve resuscitation care. Common definitions and reporting templates need to be established for the variables of CPR quality. This will allow for meaningful comparisons between treatment groups in clinical trials as well as a common system for quality improvement and documentation of this improvement. ⋯ In this report, we present the results from an international consensus working group to propose common definitions and criteria for reporting variables of CPR quality, based on the best available data for the importance of various CPR variables. The recommendations are discussed in light of the different purposes outlined above.

Out-of-hospital cardiac arrest (OHCA) is of major medical and public health significance. It also serves as a good indicator in assessing the performance of local emergency medical services system (EMS). There have been arguments for and against the benefits of advanced life support (ALS) over basic life support with defibrillator (BLS-D) for treating OHCA. ⋯ In this metropolitan EMS in Asia, the implementation of ALS services improved the intermediate, but not the final outcomes. Communities with larger populations and lower incidence of initial shockable rhythms than the OPALS study should also prioritise their resources in setting up and optimising systems of basic life support and early defibrillations. Further studies are warranted to configure the optimal care model for combating cardiac arrest.

Randomized Controlled Trial
Evaluation of M-AID, a first aid application for mobile phones.
When performed effectively, cardiopulmonary resuscitation (CPR) by bystanders reduces mortality due to sudden cardiac arrest. Telemedicine applications offer a means by which bystanders can get specific instructions for handling the emergency situation. M-AID, a first aid application for mobile phones, uses an intelligent algorithm of 'yes' or 'no' questions to judge the ongoing situation and give the user detailed instructions. The aim of this study was to evaluate the benefit of this mobile phone application in a scenario of sudden cardiac arrest. ⋯ Experience in the use of mobile phones is a prerequisite for the efficient use of the tested M-AID version. This application cannot replace skills acquisition by practical training. In a subgroup with experience in mobile phone use and basic knowledge in CPR, the device improved performance of CPR.
