2 When the heart “suddenly” fails Heart has an electrical systemSignal sent through the upper chambers (atria)Continues through lower chambers (ventricles)This signal causes the muscle to contract and relax at a regular rhythm
3 Damage hearts can have a faulty electrical system Abnormal heart rhythms that can stop the circulation of bloodIf circulation is disrupted it will eventually make it back to the heart muscle and when that fails the heart stops
5 This is a rhythm you can shock Types of RhythmsThis is a rhythm you can shock
6 If the heart suddenly stops… The victim will most likely collapse, become unconscious and stop breathingThis is where seconds count – they typically go into one of the shock-able rhythms first before complete heart stop
7 If you do nothing else…The most important thing you can do as a layperson responder is to call for help. If you don’t call…They probably don’t live.
8 During sudden heart stop – don’t forget to call 911 FIRST! If you do nothing else…During sudden heart stop – don’t forget to call 911 FIRST!
9 Using an AED Don’t stop CPR until you are ready to apply the AED AED can be used as soon as it’s available:Don’t stop CPR until you are ready to apply the AEDFollow the prompts on the machineI’m clear – you’re clear – we’re all clear
10 Precautions for an AED… Do not use alcohol to wipe the person’s chest dry – It’s flammableDo not use an AED and/or pads designed for adults on children younger than 8 or weighing less than 55 pounds unless Pediatric Pads are availableDo not use pediatric pads on a child / adult older than 8 years old. Pediatric pads deliver a lower voltage that is appropriate for children only.Don’t touch the person while analyzing or shocking
11 Precautions for an AED… Do not defribullate around flammable itemsDo not use in a moving vehicleDo not use on a person that is wet or in contact with water.Do not put the AED Pad on top of a nitroglycerin patch or other medical patch.Pacemakers do not typically present any problems with using an AED
12 How to use the AED Call 911 Remove the shirt of the victim Apply the pads to the chest as shown on the padsTurn the unit onTell everyone to “STAND CLEAR”Follow any other prompts while analyzingIf advised to shock – MAKE SURE EVERYONE IS CLEARPress the shock buttonContinue CPR
13 Water Special Situations Remove the victim from the water Dry them off Make sure you are not wet or in any water on the groundAvoid getting the unit or the pads overly wet. – Rain won’t make a huge difference as long as it’s not a monsoon!
14 Pacemakers Special Situations Usually located below the left collar bone and don’t present a problem with pad placementDo not put a pad in contact with the pacemakerIf unsure about a pacemaker, shock anyway – usually won’t make a difference.
15 Pacemakers Special Situations Usually located below the left collar bone and don’t present a problem with pad placementDo not put a pad in contact with the pacemakerIf unsure about a pacemaker, shock anyway – usually won’t make a difference.
16 Medical Patches Special Situations Remove the patch – be sure you are wearing gloves, you can receive the medication if you get it on your skin
17 Hypothermia Special Situations Be sure the victim is dry (as much as possible)Never withhold CPR or AED use while trying to re-warm someone
18 Chest Hair Special Situations Excessive chest hair may interfere with the machineUse a set of pads on the chest hair – press down hard then rip them off and remove some of the hairSome AED kits have a safety razor to remove hair also
