“…The principle is that the most common adult primary arrhythmia is VF/pulseless VT and minimal delay in the provision of a countershock improves survival. 20 The invention of the AED simplifies the training of defibrillation because it can identify the shockable rhythms and prompt actions by itself, saving time in training on skills such as ECG interpretation and the steps of the procedure. The simplicity, accuracy, and safety of these devices markedly expand the range of people who can deliver early defibrillation, which include minimally trained emergency personnel, lay and community responders, and family members of high-risk patients.…”

Objective To describe, using the Utstein template, the characteristics of patients presenting with out-of-hospital cardiac arrest to a university teaching hospital in the New Territories of Hong Kong, and to evaluate survival. Design Prospective study. Setting The emergency department of a teaching hospital in the New Territories, Hong Kong. Participants Patients older than 12 years with non-traumatic out-of-hospital cardiac arrest who were transported to the hospital between 1 July 2002 and 31 December 2002. Main outcome measures Demographic data, characteristics of cardiac arrest and response time intervals of the emergency medical service presented according to the Utstein style, and also survival to hospital discharge rate. Results A total of 124 patients were included (49.2% male; mean age 71.9 years). The majority of cardiac arrests occurred in patients' home. The overall bystander cardiopulmonary resuscitation (CPR) rate was 15.3% (19/124). The most common electrocardiographic rhythm at scene was asystole, whilst pulseless ventricular tachycardia (VT)/ventricular fibrillation (VF) was found in 18.0%. The overall survival was 0.8% (1/124), and survival to hospital discharge was significantly higher for patients with VF or pulseless VT than those patients with other rhythms of cardiac arrest (11.1% versus 0%). The median witnessed/recognised collapse to defibrillation time was 14 minutes. The median prehospital time interval from collapse/recognition to arrival at hospital was 33 minutes. Conclusion The prognosis of out-of-hospital cardiac arrest in Hong Kong was poor. Major improvements in every component of the chain of survival are necessary.

The use of Automatic External Defibrillators (AED) present in public access defibrillation programs (PAD) in cardiopulmonary resuscitation (CPR) is a challenge in the effective treatment of cardiac arrest, especially for adult patients. It is already known that the majority of adult cases of out-of-hospital cardiac arrest arise from ventricular fibrillation (VF). The most important factor in determining survival from VF is the time from collapse to defibrillation. If laypersons are trained to perform Basic Life Support (BLS) and to attempt defibrillation using an automatic external defibrillator before the emergency medical services arrive, the survival rate of an out-of-hospital cardiac arrest can be increased. In many countries, the number of public access AEDs has increased but implementation of AED use and CPR performed by public bystanders has not been sufficiently frequent. In fact, only a minority of individuals demonstrate sufficient knowledge and willingness to operate an AED, suggesting that the public is not yet sufficiently prepared. It is also very important to support the permanent campaign of training as many laypersons, starting from school, to properly use such defibrillators in public places. Considering these facts, PAD is an effective way and may be a cost-effective way to improve outcomes in cardiac arrest.

“…Automated external defibrillators (AED) can portably diagnose life-threatening cardiac arrhythmias such as VF or pulseless VT and administer defibrillating shocks accordingly to restore normal function of the heart. (6) AEDs are widely available and increasingly utilised, often by those with little to no training. (7) On commercial aircraft, there is an expectation that cabin crew should be trained to manage in-flight emergencies including use of an AED where available, and passengers who are health professionals, including paramedics, frequently respond to requests for assistance in such circumstances.…”

ABSTRACTIntroduction Automated external defibrillators (AEDs) are increasingly available in public places for the treatment of cardiac arrest. Some commercial aircraft carry an AED, but little is known about international policies and requirements. The aim is to review policy regarding AED placement on commercial aircraft, summarising reported incidence and outcomes of AED utilisation for individuals experiencing an in-flight cardiac arrest (IFCA).MethodsA scoping review was undertaken. Online databases (Medline and CINAHL) were searched using prespecified terms to identify reports evidencing use, outcome and policy of AEDS for IFCA on commercial aircraft. Reports were screened and data extracted following scoping review extraction methods. Data were analysed to describe incidence of AED use and outcomes following IFCA, and policies regarding AED placement on commercial aircraft.Results 9 observational studies were identified. 8 reported instances of successful shock delivery using AED. No published reports of safety incidents involving in-flight AED use were found. 7 studies reported survival following AED use: of these, 6 reported administration of a shock for IFCA survivors, whilst 1 study reported deployment of an AED without shock delivery. Overall, survival following in-flight AED use was 9%, with 37% survival reported where patients presented with shockable rhythm. Only one policy mandating AED placement on commercial aircraft was identified.ConclusionDespite the small, retrospective and observational nature of the reports identified, findings suggest in-flight AED use is feasible and associated with improved outcomes from IFCA.Keywords: cardiac arrest; defibrillators; AED; aircraft; flight
