COWS First Aid: A Simple Response Check | First Aid Acronyms Australia

Australian first aid acronym

COWS is a first aid response check that helps you work out whether a person can hear, open their eyes and respond.

Emergency note: if someone is seriously ill, injured, unresponsive, not breathing normally, bleeding severely, having a severe allergic reaction, or showing stroke symptoms, call Triple Zero (000) now.

Quick answer

COWS: C means Can you hear me?; O means Open your eyes; W means What is your name?; S means Squeeze my hand. COWS is a first aid response check that helps you work out whether a person can hear, open their eyes and respond.

When COWS helps

Use COWS during the response step of DRSABCD. If the person does not respond normally, call Triple Zero (000), continue the DRSABCD sequence and keep checking breathing.

Safety boundary: A remembered sequence must never delay CPR, defibrillation or a Triple Zero (000) call. If a real incident is unfolding, act on the person’s condition, call Triple Zero (000) when it is an emergency and follow the operator’s instructions.

Where it sits: COWS is commonly read alongside BLS, DRABC, ABC, ABCDE, but each term has a different job. The comparisons later on this page explain those boundaries.

Framework status: COWS is a teaching-provider response-check mnemonic, not a named ANZCOR standard. Its useful core is the observable response check described in current unconscious-person guidance.

What Does COWS Stand For?

C	Can you hear me? Speak clearly and check whether the person responds to your voice.
O	Open your eyes Ask the person to open their eyes if they can.
W	What is your name? Ask a simple question to test awareness and speech.
S	Squeeze my hand Ask for a simple physical response if safe and appropriate.

Common Mistakes

Do not shake a person roughly, especially after a fall, crash or suspected head or spinal injury.
Do not let a partial response distract you from breathing and airway checks.
Do not delay calling 000 if the person is unresponsive, confused or deteriorating.

COWS Step-By-Step For Beginners

Use this detailed sequence when learning how COWS applies to checking responsiveness before moving through DRSABCD. It connects the letters to observable checks, clear words and a useful handover rather than treating the acronym as a bare list.

Before: Safety and seriousness check. Use COWS during the Response step of DRSABCD. If the person is very unwell, injured, confused, or deteriorating, call Triple Zero (000) early and keep checking breathing.
During: C – Can you hear me?. Use a clear voice near the person, without shouting into their face. This checks whether voice alone gets a meaningful response.
During: O – Open your eyes. Ask for one simple action. If they can follow it, you have evidence they are hearing and processing at least part of what is happening.
During: W – What is your name?. Use a question they should usually know. Slurred, confused, delayed or wrong answers are worth remembering for handover.
During: S – Squeeze my hand. Ask for a simple movement only if it is safe. Do not pull, shake or force movement after a fall, crash, possible head injury or possible spinal injury.
After: Use plain-English handover. Instead of just saying “COWS positive”, tell the next responder what the person could and could not do (for example: “opens eyes to voice but can’t answer name correctly”). Pair it with AVPU if helpful.

A Real-World COWS Scenario

The scene: A person is lying still after a fall and the helper needs a simple spoken response check.

In this COWS scene, begin with C for Can you hear me?: Speak clearly and check whether the person responds to your voice. That opening prompt matters here because Use COWS during the response step of DRSABCD. If the person does not respond normally, call Triple Zero (000), continue the DRSABCD sequence and keep checking breathing. Keep the observation tied to checking responsiveness before moving through DRSABCD; in practice, watch response, airway and whether breathing is normal while emergency help and an AED are organised rather than reciting the letters without checking the person or setting.

For COWS, S closes the pattern as Squeeze my hand. Ask for a simple physical response if safe and appropriate. Before the sequence is treated as complete, relate it to when the collapse happened, what breathing looked like, when CPR started and whether an AED analysed or shocked. A specific trap to avoid is: Do not delay calling 000 if the person is unresponsive, confused or deteriorating.

Where the scenario could change: Do not shake a person roughly, especially after a fall, crash or suspected head or spinal injury. A remembered sequence must never delay CPR, defibrillation or a Triple Zero (000) call. If the facts no longer fit a stable COWS example, stop rehearsing the acronym and move to the safer emergency, clinical or workplace pathway.

COWS and similar terms

A simple prompt for checking whether someone responds. It is only one check, not the whole first-aid response.

Here is how the related terms differ:

BLS: Basic life support, including recognising an emergency, getting help, CPR and using an AED. ALS adds care from more highly trained responders.
DRABC: A shorter response sequence you may recognise from older training. For current Australian basic first aid, learn DRSABCD, which explicitly includes sending for help and defibrillation.
ABC: Airway, breathing and circulation: three key ideas in emergency care. DRSABCD gives beginners the fuller Australian basic first-aid sequence.
ABCDE: A structured check of airway, breathing, circulation, disability and exposure, used by trained responders and clinicians. It is not a replacement for the DRSABCD sequence taught in basic first aid.

Frequently asked questions

What does COWS stand for?

C means Can you hear me?; O means Open your eyes; W means What is your name?; S means Squeeze my hand. COWS is a first aid response check that helps you work out whether a person can hear, open their eyes and respond.

When is COWS useful?

Use COWS during the response step of DRSABCD. If the person does not respond normally, call Triple Zero (000), continue the DRSABCD sequence and keep checking breathing.

Is COWS the same as AVPU?

They are related but not identical. COWS gives simple prompts for checking response; AVPU gives a short handover label for the response level.

What if they answer one COWS question but seem confused?

Treat that as an abnormal response. Keep checking breathing, call Triple Zero (000) if they are deteriorating or seriously unwell, and tell the next responder exactly what they could and could not answer.

Should I shake them to get a response?

No. Use voice and gentle, safe prompts. Rough shaking is risky, especially after trauma.

How is COWS different from BLS?

COWS is framed here around checking responsiveness before moving through DRSABCD. BLS is framed around collapse, cardiac arrest, unconsciousness and the first minutes before advanced care. They may appear in the same course or incident, but they answer different questions and should not be treated as interchangeable.

When should I call Triple Zero (000)?

Call Triple Zero (000) when the person is seriously ill or injured, is deteriorating, or the urgent warning signs described on this page are present. A remembered sequence must never delay CPR, defibrillation or a Triple Zero (000) call.
