Objectives Introduction – Resus Council 2010 Primary Survey & CPR (BLS) Chain of Survival AED Statistics & Findings Definitions AED Procedures Using an AED for observation Questions

Objectives

To be able to:

1. Perform a primary survey & CPR in line with the current Resuscitation Council guidelines.

2. Use or be familiar with the use of an AED in an effectively managed resuscitation scenario.

BLS Get AED when getting help. Chest Compression depth 5-6cm. Chest Compression rate 100-120/min.

HARDER – DEEPER – FASTER Rescue breaths delivered over 1 second, do not take

more than 5 seconds for 2 breaths. DO NOT stop CPR unless signs of life present AND

breathing normally. AED training encouraged but not restrictive.

Primary Survey Danger – to? Response – establish AVPU

Shout for HELP Airway – head tilt/chin lift unless? Breathing – Look, Listen, Feel up to 10

secondsSend or go for help – 999/112 and AED

Circulation – major bleed check

Resuscitation - adult

• 999/112/AED

• 30 chest compressions

• two rescue breaths

• continue 30:2.

Chain of Survival

What increases survival? Witnessed cardiac arrest. Casualty in shockable rhythm. Effective CPR started within 4 minutes. AED used within 8 minutes.

Hospital discharge of 1676 patients in Scotland43% shocked within 4 minutes30% shocked within 5-9 minutes5% shocked within 10-14 minutes

Early DefibrillationThe scientific evidence to support early defibrillation is overwhelming; the delay from collapse to delivery of the first shock is the single most important determinant of survival. If defibrillation is delivered promptly, survival rates as high as 75% have been reported. The chances of successful defibrillation decline at a rate of about 10% with each minute of delay; basic life support will help to maintain a shockable rhythm but is not a definitive treatment.
