《2010UK心肺复苏指南：自动体外除颤器的使用指南》内容预览

Introduction

This chapter contains guidelines for the use of automated external defibrillators (AEDs)by laypeople, first responders and healthcare professionals responding with an AEDoutside hospital. These guidelines are appropriate for all types of AED, including thosethat are fully automatic. Guidelines for in-hospital use of AEDs are provided in theelectrical therapies section of the advanced life support guidelines.

In the UK approximately 30,000 people sustain cardiac arrest outside hospital and aretreated by emergency medical services (EMS) each year.

Electrical defibrillation iswell established as the only effective therapy for cardiac arrest caused by ventricularfibrillation (VF) or pulseless ventricular tachycardia (VT). The scientific evidence tosupport early defibrillation is overwhelming; the delay from collapse to delivery of thefirst shock is the single most important determinant of survival. If defibrillation isdelivered promptly, survival rates as high as 75% have been reported.23, 24The chancesof successful defibrillation decline at a rate of about 10% with each minute of delay;25basic life support will help to maintain a shockable rhythm but is not a definitivetreatment.

The Resuscitation Council (UK) recommends strongly a policy of attemptingdefibrillation with the minimum of delay in victims of VF/VT cardiac arrest.Guideline changesThere are no major changes to the sequence of actions for AED users in Guidelines2010. The ILCOR Consensus on Science and Treatment Recommendations26makesthe following recommendations which are relevant to the RC(UK) AED guidelines:
