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.

Case Reports
Ruptured left subclavian artery aneurysm presenting as upper airway obstruction in von Recklinghausen's disease.
Aneurysms arising from the subclavian artery are very rare vascular abnormalities in von Recklinghausen's disease, which often have a silent clinical presentation and are difficult to diagnose before rupture. We report a case of von Recklinghausen's disease with life-threatening upper airway obstruction caused by spontaneous rupture of the left subclavian artery aneurysm in a 46-year-old woman. The diagnosis was eventually confirmed by a reconstructed enhanced computed tomography of aorta. We emphasise the importance of it as a differential diagnosis because life-threatening upper airway obstruction may develop in such patient.

Randomized Controlled Trial Multicenter Study
Retention of CPR skills learned in a traditional AHA Heartsaver course versus 30-min video self-training: a controlled randomized study.
Bystander CPR improves outcomes after out of hospital cardiac arrest. The length of current 4-h classes in cardiopulmonary resuscitation (CPR) is a barrier to more widespread dissemination of CPR training and older adults in particular are underrepresented in traditional classes. Training with a brief video self-instruction (VSI) program has shown that this type of training can produce short-term skill performance at least as good as that seen with traditional American Heart Association (AHA) Heartsaver training, although it is unclear whether there is comparable skill retention. ⋯ Retention of CPR skills was compared 2 months post-training for adults between 40 and 70 years old who had taken either a traditional Heartsaver CPR course or a 22-min video self-directed training course. Although performance declines occurred in the 2-month interval, self-trained subjects generally demonstrated CPR skill retention equivalent to that of Heartsaver-trained subjects, although for both groups skill decline on some measures reached the level of untrained controls.

Multicenter Study
The effect of a critical care outreach service and an early warning scoring system on respiratory rate recording on the general wards.
To determine whether the implementation of a Reading-Modified Early Warning Scoring (R-MEWS) system, is associated with an increased recording of respiratory rate (RR) in hospital inpatients, and whether the presence of a critical care outreach (CCO) service has a further impact on the recording of patient's vital signs. ⋯ The introduction of an early warning scoring (EWS) was associated with improved respiratory rate recording, which may have been further enhanced by the presence of a CCO service.
