Key ACLS Principle: Quality Compressions

Deliver quality compressions for at least 60% of resuscitation time

Continuous compressions except during defibrillation

ACLS Algorithm Components

Adult Cardiac Arrest Algorithm

AHA Key Principle

Cornerstone of successful resuscitation: Deliver quality compressions for the highest percentage of time possible (at least 60%)

Shockable Rhythms (VF/pVT)

⏱️ Every 2 minutes

Shock → CPR 2 min → Rhythm check → Medications

Immediate Actions

1. Begin CPR Immediately

Push hard and fast at 100-120 beats per minute

2. Attach Monitor/Defibrillator

Check for shockable rhythm as soon as possible

3. Defibrillate if VF/pVT

200J → 300J → 360J (biphasic) or maximum available

4. Resume CPR for 2 minutes

Minimize interruptions, focus on quality compressions

💊 Medications for VF/pVT

Epinephrine
1 mg IV/IO every 3-5 minutes

First-line vasopressor for all cardiac arrest rhythms. Give as soon as IV/IO access established.

Amiodarone
300 mg IV/IO first dose, then 150 mg

For VF/pVT unresponsive to defibrillation. Give after 3rd shock.

Lidocaine (Alternative)
1-1.5 mg/kg IV/IO, then 0.5-0.75 mg/kg

Alternative to amiodarone for VF/pVT. Maximum total dose: 3 mg/kg.

Non-Shockable Rhythms (PEA/Asystole)

⏱️ Every 2 minutes

CPR 2 min → Rhythm check → Medications → Treat reversible causes

Management Strategy

1. High-Quality CPR

100-120 compressions/min, 2+ inches depth

2. Epinephrine

1 mg IV/IO every 3-5 minutes

3. Advanced Airway

Consider endotracheal intubation or supraglottic airway

4. Identify & Treat Reversible Causes

H's and T's approach

Reversible Causes (H's and T's)

H's

  • Hypovolemia
  • Hypoxia
  • Hydrogen ions (Acidosis)
  • Hyperkalemia/Hypokalemia
  • Hypothermia

T's

  • Toxins
  • Tamponade (Cardiac)
  • Tension Pneumothorax
  • Thrombosis (Coronary)
  • Thrombosis (Pulmonary)

Post-Cardiac Arrest Care

Immediate Goals

  • Optimize cardiopulmonary function and perfusion
  • Transport to appropriate facility
  • Identify and treat precipitating causes
  • Control temperature (avoid hyperthermia)
  • Optimize ventilation and oxygenation
Targeted Temperature Management
32-36°C for 12-24 hours

For comatose patients after ROSC from VF/pVT or other rhythms.

Continuous Monitoring

  • 12-lead ECG
  • Arterial blood gas
  • Chest X-ray
  • Laboratory studies
  • Neurological assessment

Adult Bradycardia Algorithm

Bradycardia Definition

Heart rate < 50 bpm with symptoms of poor perfusion

Assessment

  • Signs of poor perfusion: Altered mental status, chest pain, shortness of breath
  • Life-threatening symptoms: Shock, pulmonary edema, altered consciousness
  • ECG interpretation: Identify rhythm and QRS width

Treatment Sequence

1

Support ABCs

Give oxygen, establish IV access, monitor

2

Atropine

0.5 mg IV every 3-5 minutes (max 3 mg)

3

Transcutaneous Pacing

If available and patient is symptomatic

4

Dopamine/Epinephrine

If pacing not available or ineffective

💊 Bradycardia Medications

Atropine
0.5 mg IV every 3-5 minutes (max 3 mg)

First-line medication for symptomatic bradycardia.

Dopamine
2-20 mcg/kg/min IV infusion

Chronotropic and inotropic support for bradycardia.

Epinephrine
2-10 mcg/min IV infusion

Alternative chronotropic agent for severe bradycardia.

Adult Tachycardia Algorithm

Tachycardia Definition

Heart rate > 100 bpm - assess for stability and QRS width

Unstable (Serious Signs/Symptoms)

Immediate Synchronized Cardioversion

  • • 100-200J (start low)
  • • Increase energy if needed
  • • Sedate if possible
  • • Consider antiarrhythmic

Stable

Narrow QRS: Vagal maneuvers, adenosine
Wide QRS: Adenosine, amiodarone, procainamide

💊 Tachycardia Medications

Adenosine
6 mg rapid IV push, then 12 mg if needed

For narrow complex tachycardia. Give rapidly with saline flush.

Amiodarone
150 mg IV over 10 minutes

For wide complex tachycardia or refractory narrow complex.

Procainamide
20-50 mg/min IV until arrhythmia suppressed

Alternative for wide complex tachycardia.

Verapamil
2.5-5 mg IV over 2 minutes

For narrow complex tachycardia (avoid in wide complex).

Post-Cardiac Arrest Care

Post-ROSC Management

Comprehensive care after return of spontaneous circulation

Immediate Post-ROSC Care

  • Optimize oxygenation: Maintain SpO2 94-98%
  • Blood pressure management: SBP >90 mmHg, MAP >65 mmHg
  • 12-lead ECG: Identify STEMI or other acute coronary syndrome
  • Laboratory studies: CBC, chemistry, cardiac markers
  • Neurological assessment: Glasgow Coma Scale, pupil response

Targeted Temperature Management (TTM)

  • Indication: Comatose patients after ROSC from VF/pVT
  • Temperature: 32-36°C for 12-24 hours
  • Method: Surface cooling or intravascular cooling
  • Shivering control: Sedation, paralysis if needed
  • Rewarming: 0.25-0.5°C per hour

💊 Post-Arrest Medications

Vasopressors
Norepinephrine 0.1-2 mcg/kg/min

Maintain adequate blood pressure and perfusion.

Antiarrhythmics
Amiodarone 1 mg/min for 6 hours

Prevent recurrent arrhythmias.

Antiplatelet/Anticoagulation
Aspirin 325 mg, heparin if indicated

For suspected acute coronary syndrome.

ACLS Key Principles

  • Quality compressions are the cornerstone of successful resuscitation (≥60% time)
  • Early defibrillation for shockable rhythms
  • Epinephrine 1 mg every 3-5 minutes for all cardiac arrest rhythms
  • Amiodarone for refractory VF/pVT
  • Identify and treat reversible causes (H's and T's)
  • Post-cardiac arrest care with targeted temperature management
