Slide 1-

Automated external defibrillation Youth First Responder Course Day two I Session four 1
Slide 2-

Discuss (in simple terms) how defibrillation works. Explain and demonstrate the procedure for safe defibrillation; including pad placement and verbally and visually clearing prior to shocking. Describe the sequence of actions and skills required to use an AED in conjunction with basic principles of resuscitation. Explain problem solving techniques if a problem is encountered in a cardiac arrest situation. Overview: FIRST RESPONDER COURSE
Slide 3-

Automated external defibrillation What is defibrillation? Normally electrical impulses travel through the heart along conduction pathways in an orderly manner ‘Malfunctions’ of this circuit can result in chaotic electrical impulses (referred to as ‘fibrillation’) This means the heart is unable to respond and contract A larger than normal electrical impulse can stop this, and allow the normal electrical circuit of the heart to resume The AED delivers this impulse 3 FIRST RESPONDER COURSE
Slide 4-

Automated external defibrillation Not all patients in cardiac arrest can be shocked Needs to be a specific rhythm If the heart is electrically okay, or there is no electrical activity, shocking will have no effect The role of the AED Analyse the patients ECG Determine if here is a shockable rhythm Charge so you can deliver a shock 4 FIRST RESPONDER COURSE

Automated external defibrillation Irrespective of your type of AED, using it is as easy as 1,2,3 Turn the defibrillator on and apply the pads Analyse the rhythm Deliver the shock 5 FIRST RESPONDER COURSE

Automated external defibrillation 9 FIRST RESPONDER COURSE PRACTICAL: Using an AED
Slide 10-

Automated external defibrillation 10 FIRST RESPONDER COURSE KEY MESSAGE: Attach and use the defibrillator as soon as possible. Defibrillation must not be delayed by performing other interventions
Slide 11-

Automated external defibrillation 11 FIRST RESPONDER COURSE Troubleshooting Like all tools, occasionally defibrillators can fail This serious situation that can contribute to patient death In this setting it is important to keep a level head Troubleshooting key points Task specific personnel to focus on resuscitation Task specific personnel to focus on troubleshooting the defib Follow the defibrillator failure checklist We recommend keeping a copy of the defibrillator failure checklist with your defib

Evaluate the full cardiac arrest algorithm Understand the idiosyncrasies of single, double and multiple rescuer resuscitation Demonstrate full and effective resuscitation of a patient in cardiac arrest. Overview: 14 FIRST RESPONDER COURSE 14 Phillips MRx Lifepak 12 Lifepak 15
Slide 15-

Full resuscitation 15 FIRST RESPONDER COURSE Cardiac arrest algorithm with an AED: Perform continuous chest compressions Attach defib, *place OPA, setup bag mask Analyse rhythm shock advised? Single shock Obvious signs of life (moving, waking up)? Check safety of team and bystanders Immediate compressions at 30:2 2 minutes Yes No *Note attaching the defib and analysing takes priority over airway management if these cannot be done concurrently No

Shock and Trauma Youth First Responder Course Day TwoI Session seven 22
Slide 23-

Define trauma Discuss common causes of trauma (mechanism of injury) Discuss common injuries of trauma situations (index of suspicion) Discuss the types of shock and severity of shock Recognise the shocked patient Discuss the management of the shocked patient Overview: 23 FIRST RESPONDER COURSE
Slide 24-

Shock and trauma Trauma An injury resulting from an external force being applied to the body 24 FIRST RESPONDER COURSE
Slide 25-

Shock and trauma Mechanism of injury How the injury occurred What forces are applied during trauma This allows you to have an index of suspicion 25 FIRST RESPONDER COURSE
Slide 26-

Shock and trauma 26 FIRST RESPONDER COURSE EXERCISE 6 : Mechanism of injury Circle the joints you think would be affected as a result of this person landing on the ground. Which parts of the body do you think will be affected as a result of the imapct on these joints? What injuries might this person sustain? What differences in injury might occur if the patient was landing from a second story balcony?
Slide 27-

Shock and trauma Significant MOI Intrusion more than 0.3m into a passenger compartment Intrusion more than 0.5m into an engine compartment Car versus pedestrian > 30 km/h Death of other vehicle occupant Explosion Fall more than twice the patient’s height Motor vehicle crash > 60 km/h Object fallen on patient from >5 meters Patient ejected from motor vehicle Patient in vehicle rollover Trapped for more than 30 minutes 27 FIRST RESPONDER COURSE
Slide 28-

Shock and trauma 28 FIRST RESPONDER COURSE KEY MESSAGE: Mechanism of injury should not be considered when determining patient status
Slide 29-

Shock and trauma Shock A problem that results in inadequate circulating blood flow, and thus supply of vital nutrients to the vital organs. Shock can be caused by a number of problems. 29 FIRST RESPONDER COURSE common misconception is that ‘shock’ is a severe ‘fright’
Slide 30-

Shock and trauma Causes of shock Anaphylactic Cardiogenic Hypoadrenal Hypovolaemic Obstructive Septic Spinal 30 FIRST RESPONDER COURSE
Slide 31-

Shock and trauma Recognising shock Hypotension (low blood pressure) Absent or weak pulse Tachycardia (fast heart rate) Cool extremities Agitation Decreased LOC Delayed capillary refill time 31 FIRST RESPONDER COURSE
Slide 32-

Shock and trauma 32 FIRST RESPONDER COURSE KEY MESSAGE: If your patient has signs of shock you must call for a Paramedic or Intensive Care Paramedic.
Slide 33-

Shock and trauma What do I do if my patient is shocked? Reassure the patient Lie the patient flat with legs raised Administer oxygen if the patient has an SpO2 equal to or less than 94% Treat the cause (if possible) Seek backup from a Paramedic or Intensive Care Paramedic Transport without delay Have a low threshold for contacting the Clinical Desk 33 FIRST RESPONDER COURSE
Slide 34-

Shock and trauma 34 FIRST RESPONDER COURSE EXERCISE 7 : Recognising shock Refer to the exercise in your workbook. Do these patients have shock? Why/ why not?
