- Objectives. In a review based on estimations and assumptions, to report the estimated number of survivors after out-of-hospital cardiac arrest (OHCA) in whom cardiopulmonary resuscitation (CPR) was started and to speculate about possible future improvements in Sweden.Design. An observational study. Setting All ambulance organisations in Sweden. Subjects Patients included in the Swedish Cardiac Arrest Registry who suffered an OHCA between January 1, 2008 and December 31, 2010. Approximately 80% of OHCA cases in Sweden in which CPR was started are included. Interventions NoneResults. In 11005 patients, the 1-month survival rate was 9.4%. There are approximately 5000 OHCA cases annually in which CPR is started and 30-day survival is achieved in up to 500 patients yearly (6 per 100000 inhabitants). Based on findings on survival in relation to the time to calling for the Emergency Medical Service (EMS) and the start of CPR and defibrillation, it was estimated that, if the delay from collapse to (i) calling EMS, (ii) the start of CPR, and (iii) the time to defibrillation were reduced to <2min, <2min, and <8min, respectively, 300400 additional lives could be saved.Conclusion. Based on findings relating to the delay to calling for the EMS and the start of CPR and defibrillation, we speculate that 300400 additional OHCA patients yearly (4 per 100000 inhabitants) could be saved in Sweden.

Forskningsöversikt (refereegranskat)abstract
- Many applications of quantum communication crucially depend oil reversible transfer of quantum states between light and matter Motivated by rapid recent developments in theory and experiment, we review research related to quantum memory based oil a photon-echo approach in solid state material with emphasis on use in a quantum repeater After introducing quantum communication, the quantum repeater concept. and properties of a quantum memory required to be useful in a quantum repeater, we describe the historical development from spin echoes, discovered in 1950. to photon-echo quantum memory We present a simple theoretical description of the ideal protocol, and comment oil the impact of a non-ideal realization Oil Its quantum nature We extensively discuss rare-earth-ion doped crystals and glasses as material candidates, elaborate oil traditional photon-echo experiments as a test-bed for quantum State storage, and describe the current state-of-the-art of photon-echo quantum memory Finally, we give a brief outlook On Current research.
