First Aid in English: Words and Phrases for Emergency Situations

In a medical emergency, knowing the right words in English can make a critical difference — whether you are calling for help, giving instructions to bystanders, or communicating with paramedics on arrival. This page gives you the complete first aid vocabulary for English-speaking emergencies, from calling 999 to handing over to paramedics.

In the UK, the emergency number is 999 (though 112 also works); in the US, it is 911. The dispatcher will ask: 'Emergency services, which service do you require?' — answer clearly: 'Ambulance', 'Fire', or 'Police'. Staying calm and giving your exact location immediately is the most important thing you can do.

Three emergency scenarios covered on this page:

  • Cardiac arrest and CPR — how to call for help, instruct bystanders, guide the dispatcher, and use an AED (automated external defibrillator)
  • Injuries and bleeding — how to describe a wound (laceration, fracture, sprain), apply a compression bandage, and when to use a tourniquet
  • Allergic reactions and other emergencies — anaphylaxis, EpiPen use, seizures, heatstroke, hypothermia, poisoning, choking and the Heimlich manoeuvre

What you will find here:

  • 65 words with transcription and translation — three clusters: resuscitation (CPR, cardiac arrest, defibrillation, AED, chest compressions, rescue breaths), injuries (laceration, bruise, swelling, tourniquet, compression bandage), and other emergencies (anaphylaxis, EpiPen, seizure, hypothermia, heatstroke, poisoning)
  • 18 phrases — from 'Call 999 immediately!' to 'He's not breathing — I'm going to start CPR' and 'She's going into shock — raise her legs'
  • 20-line dialogue — complete realistic scenario: 999 call → CPR instructions → AED arrival and instructions → shock delivery → ambulance arrival → paramedic handover
  • Common mistakes — 'make CPR' vs 'perform CPR', how to give your location in English, 999 vs 911 vs 112
  • FAQ — how to describe your location, what to do for anaphylaxis, the difference between an AED and a hospital defibrillator

Calling an Ambulance — Heart Attack in a Public Place

Click the speaker icon to hear the full dialogue

💬
Dispatcher
Emergency services, which service do you require?
Caller
Ambulance, please. A man has collapsed in the street. I think he's having a heart attack.
💬
💬
Dispatcher
Is he breathing?
Caller
I'm checking now... No, he's not breathing. He's unconscious.
💬
💬
Dispatcher
You need to start CPR immediately. Kneel beside him and place both hands in the centre of his chest.
Caller
Okay. I'm doing it now. How fast?
💬
💬
Dispatcher
Push hard and fast — about 100 to 120 times a minute. I'll stay on the line with you. What is your exact location?
Caller
We're on King Street, outside the post office, near the junction with Baker Road.
💬
💬
Dispatcher
Good. The ambulance is on its way — estimated time is six minutes. Is there a defibrillator nearby?
Caller
I'm not sure. Someone's going to check the shopping centre.
💬
💬
Dispatcher
Good. Keep going with the compressions. You're doing really well. Help is on the way.
Caller
Someone's found an AED in the shopping centre — they're bringing it over.
💬
💬
Dispatcher
Excellent. When it arrives, turn it on and follow the voice instructions exactly. Don't stop the compressions until it tells you to.
Caller
It's here. I'm turning it on. It's saying 'Place pads on chest as shown.'
💬
💬
Dispatcher
Do exactly that. Everyone must stand clear when it says 'Shock advised — stand clear.'
Caller
I can hear the ambulance. They're here!
💬
Paramedic
We'll take over. Can you tell me exactly what happened and how long he's been down?
💬
Caller
He collapsed about eight minutes ago. He had no pulse when I found him. I've been doing CPR the whole time. The AED gave one shock.
💬
Paramedic
You did exactly the right thing. We've got a pulse now. Do you know if he has any medical conditions or allergies?
💬
Caller
I don't know him. He's a stranger. I just saw him fall.

Common mistakes

Avoid these common mistakes

Wrong Call 911 if you are in England.
Correct Call 999 (UK) or 112 (Europe).

911 is the emergency number in the US and Canada. In the UK you dial 999, and the pan-European number is 112 (which also works in the UK). Before travelling abroad, check the local emergency number.

Wrong He is unconscious but don't worry.
Correct He is unconscious — call for help immediately.

Unconscious is always an emergency. Distinguish: 'unconscious' — complete loss of consciousness; 'unresponsive' — does not respond to stimulation. Either condition requires calling emergency services immediately. Do not use 'fainted' as a synonym — fainting is brief, whereas loss of consciousness can be life-threatening.

Wrong I did CPR on the patient.
Correct I performed CPR on the patient.

With 'CPR' (and medical procedures in general), use the verb perform: 'I performed CPR', 'the doctor performed surgery'. 'Do' is acceptable in informal speech, but 'perform' is standard in a medical context. Also acceptable: 'to give CPR'.

Wrong I have a sprain on my ankle.
Correct I have a sprained ankle. / I've sprained my ankle.

Sprain as a noun is used differently: 'I have a sprained ankle' (adjective) or 'I've sprained my ankle' (verb in Present Perfect). 'I have a sprain on my ankle' sounds unnatural. Similarly: 'I've twisted my ankle' is an informal but widely understood alternative.

First Aid in English: Key Language Points

In a genuine emergency, clear communication in English can be the difference between effective help and dangerous confusion. Below are the most important language points for first aid situations in English-speaking countries.

Which number to call?

  • 999 — UK (police, ambulance, fire — one number, one call)
  • 911 — USA and Canada
  • 112 — universal European number (also works in the UK from any mobile, even without a SIM)
  • 000 — Australia

The dispatcher asks: 'Emergency services, which service do you require?' Answer immediately with one word: 'Ambulance', 'Fire' or 'Police'. Give your exact location right away — street name, building number, nearest landmark.

How to speak to the dispatcher

Three questions you will always be asked:
1. 'What is the emergency?' — one sentence: 'A man has collapsed and is not breathing.'
2. 'What is your exact location?' — street and number, plus a landmark: 'On King Street, outside the post office, near the junction with Baker Road.'*
3.
'Is the person conscious and breathing?'** — answer yes/no clearly

Stay on the line — the dispatcher will guide you through steps while help is on its way. Do not hang up until told to.

CPR: 'perform' not 'make'

The correct collocation is perform CPR (formal) or start CPR / do CPR (casual). Never say 'make CPR' — this is a common learner error.

Current UK guidelines (2015): for untrained bystanders, hands-only CPR is recommended — chest compressions only, no rescue breaths. Push hard and fast: 30 compressions, 5 cm deep, at 100–120 per minute. If trained, add 2 rescue breaths every 30 compressions.

Say to bystanders: 'Does anyone here know CPR?' or 'I'm going to start CPR — can someone call 999?'

AED: automated external defibrillator

An AED gives voice instructions — you do not need training to use one. Find it: 'Is there an AED nearby?' When it says 'Stand clear — shock advised', everyone must step back and not touch the patient.

FAST: recognising a stroke

UK paramedics use FAST to spot strokes quickly:
* Face — drooping on one side?
* Arms — one arm weak or numb?
* Speech — slurred or strange?
* Time — call 999 immediately; every minute counts

'I think she's having a stroke — I'm calling 999 now.'

Anaphylaxis and EpiPen

Anaphylaxis = severe allergic reaction: throat swelling, difficulty breathing, rash, drop in blood pressure. If the person has an EpiPen, inject it into the outer thigh through clothing. Then call 999: 'She's going into anaphylactic shock. I've administered the EpiPen. We need an ambulance urgently.' Even after EpiPen, the patient needs hospital assessment.

Frequently Asked Questions

The UK emergency number is 999 (police, ambulance, fire). The pan-European number 112 also works in the UK. In the US and Canada it's 911. Tip: 112 works on any mobile phone in Europe even without a SIM card.

CPR (Cardiopulmonary Resuscitation) keeps oxygen circulating when the heart has stopped. Current UK guidelines (ERC 2021) recommend hands-only CPR for untrained bystanders: push hard and fast in the centre of the chest — 30 compressions, about 5 cm deep, at 100–120 per minute. Do not stop until paramedics take over. Use the correct phrasing: 'I'm performing CPR' (not 'making CPR', which is ungrammatical).

Say: 'The person is unconscious and not breathing' or 'He/She is unresponsive'. The dispatcher will ask: 'Is he/she breathing normally?' — answer honestly. The dispatcher will then guide you through CPR while staying on the line.

FAST is a mnemonic for recognising a stroke: Face (drooping?), Arms (one weaker?), Speech (slurred?), Time (call 999 immediately!). If any sign is present, call emergency services without delay.

If the person cannot speak, cough or breathe, perform the Heimlich manoeuvre: stand behind them, wrap your arms around their waist, make a fist with one hand just above the navel, cover it with your other hand, and deliver sharp inward-upward thrusts. Say: 'I'm going to perform the Heimlich manoeuvre. Stay still.'

The recovery position (on the side) prevents an unconscious person from choking on vomit. Use it when the person is unconscious but IS breathing and has a pulse. If there is no breathing — start CPR immediately. Command: 'Put him in the recovery position.'
