Acute Stroke in ACLS: Recognition, Timing and First Steps

In acute stroke, brain is lost every minute, and the most effective treatments are only possible within time windows. The ACLS course teaches clinicians to recognise stroke and get the patient to definitive care fast.

Recognising stroke

Sudden facial droop, arm or leg weakness, speech difficulty, loss of vision, loss of balance or a sudden severe headache. Prehospital stroke scales help structure the assessment.

Time last known well

The single most important fact is when the patient was last known to be normal. It decides eligibility for time-dependent treatments. If they woke with symptoms, that time is when they were last seen well.

First steps

• Support airway, breathing and circulation — see the systematic approach.
• Check glucose: low blood sugar can mimic stroke.
• Alert the stroke team or pre-notify the receiving hospital.
• Rapid brain imaging to distinguish bleeding from blockage.

Treatment

For eligible patients with ischaemic stroke, fibrinolysis and endovascular clot retrieval are time-dependent treatments given in specialist settings. ACLS focuses on getting eligible patients there without delay.

Why stroke is in ACLS

Stroke and cardiac emergencies share a need for fast recognition and a systems approach. ACLS pairs stroke with acute coronary syndromes for that reason. Paramedics see stroke first — see ACLS for paramedics.

This guide summarises what the ACLS course teaches for education only. It is not a clinical protocol: follow the current American Heart Association guidelines, linked below, and your institution’s policies.

Frequently asked questions

What is the most important fact in suspected stroke?

The time the patient was last known to be well.

Why check glucose in suspected stroke?

Low blood sugar can mimic stroke.

Why is brain imaging needed?

To distinguish bleeding from a blocked artery before treatment.

Is stroke part of ACLS?

Yes, recognition and early management of acute stroke are included.

Can stroke be treated after many hours?

Some patients are eligible for specialist treatment later; the stroke team decides.
