Definition

ACLS is geared towards healthcare professionals who either direct or participate in the management of cardiopulmonary arrest or other cardiovascular emergencies or personnel in emergency response. Upon successful completion of the course, students receive a course completion card, valid for two years.

Advanced cardiac life support (ACLS) is a group of procedures and techniques that treat immediately life-threatening conditions, including cardiac arrest, shock, stroke, and trauma. ACLS procedures and techniques are arranged into algorithms. Algorithms are a set of standard guidelines that improve the speed, effectiveness, and outcomes of ACLS. The goal of ACLS is to stabilize your condition. This includes restoring normal vital signs and alertness. ACLS and other types of intensive medical care save lives. ACLS generally does not reverse or cure an underlying end-stage or life-threatening condition. It is not successful in all cases. Do-not-resuscitate (DNR) options that do not use ACLS may be appropriate in some cases, such as in end-stage cancer. Discuss all end-stage disease treatment options with your doctor to understand which choices are best for you or your family member. You can specify your choices ahead of time. Types of ACLS treatments Some conditions and diseases require

A team of specially trained healthcare providers performs advanced cardiac life support (ACLS). ACLS teams generally include doctors, nurses, and respiratory therapists. The following doctors perform advanced cardiac life support (ACLS): Cardiac surgeons specialize in the surgical treatment of conditions of the heart and its blood vessels. Cardiac surgeons may also be known as cardiothoracic surgeons. Cardiologists specialize in the medical treatment of heart disease. Critical care medicine doctors specialize in the diagnosis and management of life-threatening conditions. Emergency medicine and trauma doctors specialize in rapidly diagnosing and treating acute illnesses, conditions, injuries, and complications of chronic diseases. Thoracic surgeons specialize in the surgical treatment of diseases of the chest, including the blood vessels, heart, lungs, and esophagus. Thoracic surgeons may also be known as cardiothoracic surgeons.

Immediate

Presumption: Out-of-hospital cardiac arrest with minimal resources
Check pulse, if pulseless
Begin CPR
Attach monitor/defibrilator
Rhythm shockable?
Give oxygen if available
Definitive treatment is transferred to the nearest emergency department

V-Fib and Pulseless V-Tach (Shockable)

ACLS Algorithm

Shock as quickly as possible and resume CPR immediately after shocking
- Biphasic – 200J
- Monophasic – 360 J
Give Epinephrine 1mg if (shock + 2min of CPR) fails to convert the rhythm
Give antiarrhythmic if (2nd shock + 2min of CPR) again fails
- 1st line: Amiodarone 300mg IVP with a repeat dose of 150mg as indicated
- 2nd line: Lidocaine 1-1.5mg/kg then 0.5-0.75mg/kg q5-10min
- Polymorphic V-tach: Magnesium 2g IV, followed by a maintenance infusion

Asystole and PEA (Non-Shockable)

Epinephrine 1mg q3-5min

Mechanism of PEA

Three major mechanisms of PEA (3 & 3 Rule)
- Severe Hypovolemia (or dehydration in athletes)
- Obstruction
  - Tension pneumothorax
  - Cardiac tamponade
  - Massive Pulmonary embolism
- Pump Failure

Treatable ACLS Conditions (H’s and T’s)

Hypovolemia
Hypoxemia
Hydrogen ion (i.e. severe acidemia)
Hypokalemia/Hyperkalemia
Hypothermia/Heat Stroke
Tension Pneumothorax
Cardiac Tamponade
Toxicology including Performance Enhancing Drugs‎
Thrombosis, pulmonary
Acute Coronary Syndrome

PEA Evaluation by QRS

A differential based on QRS being narrow or wide and aided by ultrasound

QRS Narrow

Mechanical RV Problem – Ultrasound should show hyperdynamic LV and potential cause
- Cardiac Tamponade
- Tension Pneumothorax
- Deterioration after intubation
- Pulmonary Embolism
- Acute Coronary Syndrome

QRS Widened

Metabolic LV Problem – Ultrasound should show hypokinetic LV
- Hyperkalemia
- Sodium-channel blocker toxicity (Ex. Tricyclic (TCA) toxicity)
- Agonal rhythm
- Acute Coronary Syndrome

General

A: Adjunct – Place oropharyngeal airway
B: Breathing – Attach to bag valve mask (BVM)
C: Compressions – Switch out providers q pulse check (ever 2 minutes)
D: Defibrillation
- May be ok to shock during compressions if wearing gloves and using biphasic device^[1]
- Precharge prior to pulse & rhythm check to increase overall compression time
E: Exposure
Other
- Consider placing IO if unable to obtain IV access
- Use ultrasound to evaluate for possible correctable etiologies

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

Write when the problem started and how it changed.
Bring old prescriptions, investigation reports, and current medicines.
Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

What is the most likely cause of my symptoms?
Which danger signs mean I should go to hospital quickly?
Which tests are necessary now, and which can wait?
How should I take medicines safely and what side effects should I watch for?
When should I come for follow-up?

Tests to discuss

Vital signs: temperature, pulse, blood pressure, oxygen saturation
Basic physical examination by a clinician
CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

Avoid heavy lifting, sudden bending, and prolonged bed rest.
Use comfortable posture and gentle movement as tolerated.
Discuss physiotherapy, X-ray, or MRI only when clinically needed.

OTC medicine safety

For mild back pain, pain-relief medicine may be discussed with a doctor or pharmacist.
Avoid repeated painkiller use if you have kidney disease, stomach ulcer, uncontrolled blood pressure, or are taking blood thinners.

Avoid these mistakes

Do not start antibiotics without a proper medical decision.
Do not use steroid tablets or injections casually for quick relief.
Do not delay emergency care because of home remedies.

Get urgent help if

Back pain with leg weakness, numbness around private area, loss of urine/stool control, fever, cancer history, or major injury needs urgent care.

Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

For rural patients and family caregivers

Patient health record and symptom diary

Write your symptoms, medicines already taken, test results, and questions before visiting a doctor. This note stays on your device unless you print or copy it.

Doctor to discuss: Doctor / qualified healthcare provider

Tests to discuss with doctor

Basic vital signs: temperature, pulse, blood pressure, oxygen level if needed
Relevant blood, urine, imaging, or specialist tests only after clinical assessment

Questions to ask

What is the most likely cause of my symptoms?
Which warning signs mean I should go to emergency care?
Which tests are really needed now?
Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Go to emergency care if you notice:

Severe or rapidly worsening symptoms
Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration

Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.

Step 1
Check danger signs first

If danger signs are present, seek emergency care and do not wait for online information.
Step 2
Record the symptom story

Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.
Step 3
Visit a qualified clinician

A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.
Step 4
Do only useful tests

Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.
Step 5
Follow up and return early if worse

If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips

Take a written symptom diary and all previous prescriptions/test reports.
Do not hide medicines already taken, even herbal or over-the-counter medicines.
Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
