1. 1 Automated External Defibrillator

2. 2 Sudden Cardiac Arrest Sudden cardiac arrest is the most common cause of death in Australia. Sudden Cardiac Arrest can occur when the heart’s electrical system malfunctions causing rhythms that are rapid (pulseless ventricular tachycardia) or chaotic (ventricular fibrillation), or both. The irregular heart beat causes the heart to suddenly stop beating in a coordinated manner.

3. 3 Without CPR, with effective compressions, the heart will continue its rapid uncoordinated twitching or fluttering until, due to the lack of oxygenated blood in the heart muscle, the muscle tires and completely stops, with no electrical or mechanical activity. Sudden Cardiac Arrest

4. 4 Chain of Survival

5. 5 Send for Help Immediately send for help - request an ambulance Send someone to locate the AED

6. 6 Early CPR Commence CPR with compressions immediately

7. 7 Early CPR Effective compressions moves oxygenated blood to the brain

8. 8 Early CPR Effective compressions moves oxygenated blood to the heart

9. 9 Early Defibrillation Defibrillation shocks the heart – resetting cardiac electrical activity Defibrillation does not restart the heart

11. 11 Advanced Life Support

12. 12 Get to know your AED Batteries OK Check CPR D-Padz is in date ( leave the tag hanging out)

13. 13 Buttons and Controls ON/ OFF SHOCK BUTTON

14. 14 Audible Prompts “Attach defib pads to patients bare chest” “Stay Calm - Check Responsiveness” “Call for help” “Open Airway” “Don’t touch patient analysing” “Shock advised. Don’t touch patient. Press flashing shock button” “Start CPR” or “No shock advised” “Start CPR”

15. 15 Graphical User Interface Flashing Indicator Light

16. 16 LCD Screen Display Compression depth indicator Audible prompts whilst doing compressions “Push Harder” or “Good Compressions” as well as visual prompts

17. 17 CPR-D Padz Sensors in the Defib Pads (called CPR-D Padz) gives instantaneous feedback concerning DEPTH and RATE of heart compressions

18. 18 Operating your AED Turn the AED on and follow the prompts….. “Stay Calm - Check Responsiveness” “Call for help” “Open Airway”

19. 19 Use the AED lid to maintain an airway You can place the AED lid between the shoulders of the casualty to help facilitate a held tilt and open airway.

20. 20 This may require cutting through under garments to expose skin using the scissors supplied in the ready kit, or trauma sheers from your first aid kit. “Attach Defib Padz to the chest” Bare the casualty’s chest

21. 21 “Attach Defib Padz to the chest”..dry the casualty’s skin (if required) using the paper towel in the ready kit...trim excessive chest hair (if required) on the upper right side and lower left of the chest, using scissors and /or razor in the ready kit. To help ensure proper adhesion of the Defib Padz…

22. 22 “Attach Defib Padz to the chest” Open the CPR-D Padz and place the CPR sensor (cross) in the middle of lower half of the sternum (breastbone). Peel the backing off the Padz 2 and 3 and stick firmly to the skin

23. 23 Do not place Defib Pads directly over a casualties implanted pacemaker, usually placed just under the skin on the chest, normally just below the left collarbone (look for the scar). Position the Defib Pads at least 8 cm away from the pacemaker. “Attach Defib Pads to the chest”

24. 24 “Don’t touch patient analysing” The AED will analyse the casualties heart rhythm and determine if a shock should be administered

25. 25 Shock or No Shock? If the AED detects a shockable rhythm (VT or VF) you will get an audible prompt: “Shock advised. Don’t touch patient. Press flashing shock button” If the AED does not detect a shockable rhythm you will get audible prompt: “No shock advised” “Start CPR” and CPR should be performed for another two minutes. Follow the AED prompts

26. 26 “Shock Advised” The operator of the AED will call loudly “Stand clear” and check to ensure no one is touching the casualty before pressing the shock button. The AED will prompt – “Shock Delivered”

27. 27 Continue CPR with 30 Compressions Followed by 2 Rescue Breathes Continue the 30:2 ratio for another 2 minutes “No shock advised”

28. 28 Ensure effective compressions Effective CPR may lead to a shockable rhythm

29. 29 Ensure effective compressions After 2 minutes the AED will prompt you “Stop CPR”, “Don’t touch patient. Analyzing”

30. 30 Post-defibrillation care If the defibrillation has been successful: leave the pads on the casualty check breathing ? If the casualty is breathing - check for a response (if they are responsive, reassure them and make them comfortable / if they are not responsive, place them in the lateral position and carefully monitor) If the casualty is not breathing, continue CPR

31. 31 Servicing The Zoll AED Plus requires servicing every 5 years irrespective of usage. D/T/Zs will coordinate the servicing of your AEDs. Do not undertake any servicing activities yourself.

32. 32 After use checks NSWRFS AEDs will be replaced ‘one for one’ following any operational use to facilitate servicing and replacing consumable items, including the CPR-Padz. AED electrodes (Padz) are a one use only item.
