Home Automatic External Defibrillator
Home - Why we use the AED? - How to use the AED? - Indications for the AED? - Contraindications to AED? Objectives for this subject
Home The chain of survival: - early access to 911 -early CPR -early defibrillation -early advanced care
Home Defibrillation is the application of electrical shock to help restore the hearts regular rhythm
Home Defibrillator is the device used to deliver that shock and it can be manual or automatic.
Home Early defibrillation is the single most important factor in determining survival from cardiac arrest.
Home Defibrillation should be performed with in the first 8 minutes after cardiac arrest. Ideally, the sooner, the better.
Home AED Most common initial rhythms patients go into as they enter into cardiac arrest are:
Home 2 Shockable Rhythms V-Tach and V-Fib
Home Ventricular Tachycardia: Fast heart rhythm which does not allow the heart to fill properly and cardiac output is compromised and reduced.
Home Ventricular Fibrillation: disorganized series of electrical discharges in the ventricles. Where the ventricles quiver.Stops Cardiac output and hearts pumping ability.
Home AEDs that are available are automatic and semi-automatic.
Home Automatic: where machine does all of the work. Semi Automatic: where machine tells you when to push button to deliver shock.
Home Apply AED as soon as you determine that your patient is not breathing and does not have a pulse.
Home Always making sure that CPR is still in progress while you are setting up the AED. If by yourself, apply the AED.
Home Ensure before putting pads on chest, it is clear of all patches, paste or pacemakers. Dont cover something up with pad.
Home If patient has hair on chest that could interfere with conduction, make sure you shave it off with razor provided to you.You want pads on chest to fit snug and secure.
Home White is negative Red is positive Now attach the adhesive pads to the cables remembering- White is negative, anterior chest wall. Red is positive, left anterior axillary line.
Home Do Not Utilize The Anterior – Posterior (Front and Back) Lead Placement For Automatic Defibrillation
Home Now turn on machine and wait for AED to analyze the patients rhythm. Making sure that CPR has been stopped for machine to detect rhythm.
Home While waiting for machine, you can begin your patient information by speaking clearly into the tape recorder of the machine. You want to give certain information.
Home - Patients age. - Patients past medical history. - Patients medications. - Brief description of what happened prior to your arrival.
Home CLEAR When machine advises a shock is indicated,CLEAR your patient. Ensuring that no one is touching patient or stretcher.
Home Clear Patient When the AED delivers a shock it will go back and reanalyze the rhythm. If another shock is appropriate Clear Patient and deliver the shock.
Home Sets of 3 shocks are called stacked shocks and they are done without any pauses to check patients pulse or administer CPR
Home If No shock is indicated: -Check breathing give appropriate oxygen therapy. -Check pulse, if no pulse! Start CPR for 1 minute and then have the AED reassess.
Home Transport patient when: *Patient regains a pulse *Total of 6 shocks have been given. *AED has indicated 3 no shockswith intervening CPR.
Home Defibrillator Some ALS providers will choose to leave the AED in place. Some will choose to use their monitor for manual defibrillation.
Home Safety should always be maintained by the provider: -Not using near or around water -Ensuring all med patches and pastes are off the patient. -Making sure that everyone is clear of the patient when the shock is delivered.
Home Indications for AED Indications for AED * Unresponsive * Apneic * Pulseless patients.
Home Adult Patients > 8 years old > 55 lbs. Unresponsive,pulseless and apneic.
Home Contraindications: Infants and children < 8 years old < 55 lbs.
Home Hypothermia Contraindications: !! Hypothermia !! (Contact medical control)
Home Contraindications: Rigor / Livor Mortis No Code /DNR
Home The AED cant properly analyze patient in moving ambulance. It is recommended that you stop the medic and let AED do its job.
Home Please review your Regional Medical Protocol Manual for further information
