CPR Statistics
Sudden Cardiac Arrest
EMS treats nearly 300,000 victims of out-of-hospital cardiac arrest each year in the U.S.
Less than eight percent of people who suffer cardiac arrest outside the hospital survive.
Sudden cardiac arrest can happen to anyone at any time. Many victims appear healthy with no known
heart disease or other risk factors.
Sudden cardiac arrest is not the same as a heart attack. Sudden cardiac arrest occurs when electrical
impulses in the heart become rapid or chaotic, which causes the heart to suddenly stop beating. A heart
attack occurs when the blood supply to part of the heart muscle is blocked. A heart attack may cause
cardiac arrest.
Cardiopulmonary Resuscitation (CPR) Less than one-third of out-of-hospital sudden cardiac arrest victims receive bystander CPR.
Effective bystander CPR, provided immediately after sudden cardiac arrest, can double or triple a
victims chance of survival.
The American Heart Association trains more than 12 million people in CPR annually, including
healthcare professionals and the general public.
The most effective rate for chest compressions is 100 compressions per minute the same rhythm as
the beat of the BeeGees song, Stayin Alive.
Automated External Defibrillators (AEDs)
Unless CPR and defibrillation are provided within minutes of collapse, few attempts at resuscitation
are successful.
Even if CPR is performed, defibrillation with an AED is required to stop the abnormal rhythm andrestore a normal heart rhythm.
New technology has made AEDs simple and user-friendly. Clear audio and visual cues tell users what to
do when using an AED and coach people through CPR. A shock is delivered only if the victim needs it.
AEDs are now widely available in public places such as schools, airports and workplaces.

Essentials of ACLS
CORE of ACLS Concepts
y Cerebral Resuscitation is the most important goal!y Returning the patient to the pre-arrested level of neurological functioningy Cardio-Pulmonary-Cerebral resuscitation (CPCR) had been proposed to replace
CPR
y Focuses on Airway and Ventilation, Basic CPR, Defibrillation of Ventricular fibrillation and Drugsy The probability of survival declines with each passing minute of cardiopulmonary compromisey Medical conditions that lead to cardiac arrest must be identified as quickly as possible (e.g. AMI)y The chain of survival applies in all settings.y Good ACLS requires a careful thought about when to start and when to stop resuscitativeefforts.
The Chain of Survival

The corepurpose of ACLS&ECC
To provide effective care ASAP, aim for a rapid restoration of spontaneous circulation and give the best
chance of recovery, thus it would include:
> Pre-arrest cares,
>CPR(BLS & ACLS) & ECC, and
> Post-resuscitation cares.
ACLS:
y impacts multiple key links in the chain of survival that include:y interventions to prevent cardiac arresty treat cardiac arrest, andy improve outcomes of patients who achieve return of spontaneous circulation
(ROSC) after cardiac arrest.
y ACLS interventions aimed at preventing cardiac arrest include:y airway managementy ventilation support, andy treatment of bradyarrhythmias and tachyarrhythmias.
y For the treatment of cardiac arrest, ACLS interventions build on the basic life support (BLS)foundation of:
y immediate recognition and activation of the emergency response systemy early CPR, andy rapid defibrillation to further increase the likelihood ROSC with drug therapy,
advanced airway management, and physiologic monitoring.
y Following ROSC, survival and neurologic outcome can be improved with integrated postcardiacarrest care.
The Basics
ACLS always starts with BLS!
Are you OK? Is the patient conscious? Call for help. Do C-A-B
Circulation- check pulse, start CPR!Airway- Is it
open?
Breathing- moving air?
Defibrillation- if VF or pulseless VT

4/13
Drugs Given Via ET Tube
Narcan Preferred route is IV/IO
Vasopressin
Epinephrine
Lidocaine
ACLS CORE DRUGS
Epinephrine (Adrenaline)
Mechanism of Action
- - and -adrenergic activity Indication(s)
y VF / pulseless VT unresponsive to defibrillationo ACLS Class IIb Recommendation
y Asystole / PEAo ACLS Class Indeterminate Recommendation
y Symptomatic bradycardia, severe hypotension, & anaphylaxis Standard dose = 1 mg every 3-5 minutes
Follow each dose with saline flush
May be given via ET tube (double the dose)
High dose / Escalating dose
No longer recommended No improvement of survival or neurological outcomes
May contribute to post-tx myocardial dysfunction
Epinephrine Drip
Initiate at 1 mcg/min, titrate to hemodynamic endpoint(2-10 mcg/min)
Precautions
If given via ET Tube, double the dose
except Vasopressin (insufficient
evidence torecommend a dose)

5/13
Naturally occurring antidiuretic hormone
Acts as non-adrenergic peripheral vasoconstrictor
Direct stimulation of smooth muscle V1 receptors
Does not increase myocardial O2 consumption (No beta effects)
Levels higher in patients who survive CPR
Indication(s)
- VF / pulseless VT unresponsive to defibrillation
o ACLS Class IIb Recommendation)- Asystole / PEA
o ACLS Class Indeterminate Recommendation)Vasodilatory shock (i.e. septic shock)
May be helpful in prolonged arrest (Longer half-life than epinephrine)
Dose is 40 units IV x1 dose
alternative to 1st or 2nd dose of epinephrine
Re-dosing (Class Indeterminate)
If no response in 10-20 minutes, resume epinephrine, do not repeat doses of vasopressin
Re-dosing vasopressin seems rational, but is not supported by human-data.
Some practitioners will re-dose vasopressin, this is not supported by ACLS recommendations.
Precautions
Hypertension, Tremor
Myocardial Ischemia, Angina
Increased peripheral vascular resistance Overdose treatment is supportive
Consider osmotic diuretics if severe overdose
Miscellaneous
Provided as 20 unit/mL ampule
Lidocaine
Mechanism of Action
Depresses diastolic depolarization & automaticityin the ventricles
Indication(s)
Persistent or recurrent VF / pulseless VT
oACLS Class Indeterminate Recommendation
o Most useful in sustained VF / pulseless VT orwide-complex tachycardia of unknownorigin
Perfusing arrhythmias
Cardiac Arrest (VF/pulseless VT) given as
1 1.5 mg/kg IV initially
Repeat doses of 0.5 0.75 mg/kg ( of initial dose)
IV every 5-10 min for a total of 3 doses (or) 3 mg/kg
May give via ET tube (double the dose)
Lidocaine Drip
Start at 1-4 mg/min to achieve levels of
1.5 6 mcg/mL
Reduce maintenance infusion if hepatic impairment
Constant ECG monitoring is necessary w/ infusions
Precautions
Bradycardia, hypotension, heart block, sinus nodedepression, N/V, double vision, dyspnea
Excessive drowsiness is a sign of high blood levels leading to seizures, loss of consciousness,
coma
Stop infusion immediately, draw levels
Adenosine (Adenocard)

Aspirin: 325 mg tablet (chewable)
Remember: MONA greets all patients
Medication Overdose
Naloxone (Narcan)
Reverses opiate activities, including respiratory depression from natural & synthetic opioids
0.4 2 mg every 2-3 min up to 10 mg
Duration of 20-60 min, typically shorter than most opioids so will need repeat doses
May be given via the ET tube (double the dose)
Flumazenil (Romazicon)

Classification of VF/VT
Persistent (shock resistant): persists after multiple shocks
Refractory: persists after shocks, CPR, airway, AND drugs
Recurrent: returns after a successful intervention

Ten Commandments for ACLS
1. Do good CPR: do CPR when indicated, refrain when not indicated, and do well
2. Highest priority is the primary survey & hunt for VF
3. The next highest priority is the secondary survey
4. Know the defibrillator! : familiarize and do daily maintenance check
5. Search for reversible or treatable causes.
6. Know the ECC medications: Why?, When?, How?, and Watch out?!?
7. Be a good team: conductor or member
8. Practice the phase response resuscitation format: anticipation/entry/resuscitation/ maintenance/
family notification/ transfer/critique
9. Determine code status in advance
10. Learn and practice the most difficult resuscitation skills*:
when not to start CPR
when to stop CPR
how to tell the family members
how to talk with your colleagues
