Describe the relationship of the chain of survival to successful resuscitation of the cardiac arrest patient.
Review AHA BLS guidelines. Demonstrate cardiac arrest management
following ACLS guidelines. Discuss the interventions required to ensure good
outcomes with Return of Spontaneous Circulation.

Cardiovascular disease is the number one cause of death in the U.S., and many times the first indication of this disease is an acute coronary event
Cardiac arrest is the most severe manifestation of an acute coronary syndrome, and with rapid intervention EMS providers can make the difference between life and death
![Page 4: als cardiac arrest and rosc](https://reader036.fdocuments.net/reader036/viewer/2022062617/54bdbc354a79598b3b8b4590/html5/thumbnails/4.jpg)
However, not every cardiac arrest is preceded by chest pain or discomfort, nor do all patients with chest discomfort or pain proceed to cardiac arrest, but for those who do, rapid intervention is vital. Without it, such patients will almost surely die. As such, the EMT must be prepared to treat all patients with signs and symptoms of cardiac compromise as cardiac emergencies.
![Page 5: als cardiac arrest and rosc](https://reader036.fdocuments.net/reader036/viewer/2022062617/54bdbc354a79598b3b8b4590/html5/thumbnails/5.jpg)
Few cardiac arrest patients survive outside a hospital without a rapid sequence of events.◦ Chain of survival:
Early recognition and activation of EMS Immediate bystander CPR Early defibrillation Early advanced cardiac life support Integrated post-arrest care
![Page 6: als cardiac arrest and rosc](https://reader036.fdocuments.net/reader036/viewer/2022062617/54bdbc354a79598b3b8b4590/html5/thumbnails/6.jpg)
Why is CPR Important◦ Studies have shown that the general population
will start CPR only 1/3 of the time and only 15% of that total is done correctly
◦ Chest Compressions can be started within 18 seconds of arriving at the patient, whereas airway management first can delay compressions by 1-2 minutes or more
◦ CPR prolongs the period during which defibrillation can be effective
![Page 7: als cardiac arrest and rosc](https://reader036.fdocuments.net/reader036/viewer/2022062617/54bdbc354a79598b3b8b4590/html5/thumbnails/7.jpg)
Ventricular fibrillation is the most frequent rhythm found in cardiac arrest
Defibrillation is the most effective treatment for VF
Probability of successful defibrillation diminishes with time
VF will lead to asystole quickly without proper treatment

“Hearts and Brains are going to die”◦ Peter Safar MD
EMS has the most opportunity to perform CPR, so we should be good at performing good, quality CPR

1. Make sure the scene is SAFE!2. Check responsiveness and breathing..!3. If alone call for help and announce for
code blue4. Check for a pulse and if no pulse present
begin CPR Always start CPR with Compressions First!
![Page 11: als cardiac arrest and rosc](https://reader036.fdocuments.net/reader036/viewer/2022062617/54bdbc354a79598b3b8b4590/html5/thumbnails/11.jpg)
Always start CPR with Compressions First!
Push hard and fast Rate should be at least 100 per minute&
depth B/W 3-5 cm Provide 30 compressions then 2 breaths Make sure the chest is allowed to re-expand
completely at the end of each compression
![Page 12: als cardiac arrest and rosc](https://reader036.fdocuments.net/reader036/viewer/2022062617/54bdbc354a79598b3b8b4590/html5/thumbnails/12.jpg)
Chest compressions and breaths are the same for adults, child, and infant if you are alone◦Adult age starts at the onset of puberty (12-14 years of age)◦Child is age 1year to the onset of puberty◦Infant is anyone under the age of 1year
![Page 13: als cardiac arrest and rosc](https://reader036.fdocuments.net/reader036/viewer/2022062617/54bdbc354a79598b3b8b4590/html5/thumbnails/13.jpg)
5. Open the airway with head tilt-chin lift6. Place the mask on the patient’s face7. Use the E-C clamp technique8. Deliver each breath over 1 second

1. Initiate CPR and attach monitor/defibrillator2. Defibrillate at 360j or equivalent biphasic shock3. Resume CPR immediately following defibrillation and
continue for 2 minutes4. Initiate vascular access; manage airway5. Reevaluate rhythm; defibrillate if needed; resume
CPR6. Administer Epinephrine 1mg every 3-5 minutes7. Defibrillate if needed; resume CPR8. Administer Amiodarone 300mg; may repeat at
150 mg IV/IO in 5 minutes if needed. 9. Continue cycles of CPR and defibrillation as needed
