COPD First Aid: Helping a Breathless Patient and Using Oxygen Safely

COPD first aid is about helping someone with chronic obstructive pulmonary disease, also known in some countries as chronic obstructive airway disease (COAD), through a sudden worsening of their breathing. People with emphysema, chronic bronchitis or long-standing asthma-type airway damage have lungs that move oxygen and carbon dioxide poorly. A chest infection, smoke, fumes or exertion can tip them from “usual breathless” into an emergency. This guide explains what to look for, what to do, and why oxygen needs particular care.

Recognising When COPD First Aid Is Needed

• Worsening breathlessness, often with a wheeze and a prolonged breath out
• Difficulty speaking in full sentences, or being unable to speak
• A fast pulse in the early stages, and sometimes a slow pulse when the person is exhausted and severely ill
• Pale, sweaty skin and blue tinge to the lips, ears or fingernails
• Exhaustion, agitation, confusion, drowsiness or a blank stare

Confusion or drowsiness is a late and dangerous sign, because it can mean carbon dioxide is building up in the blood.

COPD First Aid Steps for a Conscious Patient

1. Call for urgent help if breathing is severe, speech is limited to a few words, lips are blue, or the person is confused or drowsy. Otherwise arrange urgent medical advice.
2. Position them upright. Help them sit leaning slightly forward, supported by a table, chair back or pillows. Do not lay them flat.
3. Reassure and slow things down. Anxiety speeds breathing and makes it less effective. Use a calm voice and encourage slow, steady breaths.
4. Loosen tight clothing around the neck, chest and waist.
5. Help with their own medication. If they have a prescribed reliever inhaler or an action plan, help them follow it exactly.
6. Record observations. Note breathing rate, pulse, level of alertness, skin colour and effort of breathing every few minutes, as described in our vital signs observations guide.
7. Stay with the person until medical help takes over. Do not leave them alone.
8. Be ready for deterioration. If they stop responding or stop breathing normally, follow the DRABC primary survey and start CPR.

COPD First Aid and Oxygen: Why It Is Different

In many healthy people the main trigger to breathe is the carbon dioxide level in the blood. In some people with long-standing COPD, carbon dioxide stays high all the time and the breathing drive becomes more sensitive to low oxygen. Giving too much oxygen can reduce that drive, so breathing slows and carbon dioxide rises further, even though oxygen levels look good.

This does not mean oxygen should be withheld from a patient who is seriously unwell. It means it should be given by someone trained, in controlled low amounts, with regular checks of breathing rate and alertness. Clinical guidelines for COPD generally aim for a blood oxygen saturation of about 88 to 92 per cent in patients at risk of this problem, and your local protocol or ambulance service will set the details. Untrained rescuers should not start oxygen themselves.

If a person is on oxygen, keep it running until responders take over, and check vital signs about every five minutes.

COPD First Aid Warning Signs of Breathing Failure

Call the emergency number straight away and be ready to support breathing if:

• The breathing rate falls below about 12 breaths a minute and the person is drowsy or confused
• Their effort to breathe visibly decreases while they look worse
• They stare blankly, are sweating heavily and respond poorly

These signs mean the person may need help to ventilate. Trained rescuers can assist using the methods in our expired air resuscitation techniques guide while the ambulance is on its way.

Reducing the Need for COPD First Aid

People with COPD benefit from stopping smoking, keeping vaccinations such as influenza and pneumococcal current, avoiding dust and fumes, and having a written action plan agreed with their doctor. Workplaces where COPD triggers such as dust, welding fumes or chemical vapours are present should apply exposure controls and make sure first aiders know which workers have a known chest condition.

Frequently Asked Questions

Is COPD the same as asthma?
No. Asthma is usually reversible and often triggered by allergens, while COPD involves lasting lung damage. The two can occur together, and the first aid for severe breathlessness overlaps. See our asthma attack guide for comparison.

Can a first aider give oxygen to a COPD patient?
Only if trained and permitted by local protocol, using controlled low-flow oxygen and checking the person regularly. Otherwise, focus on positioning, reassurance, their own medication and calling for help.

What is the safest position?
Upright and leaning slightly forward, supported. Lying flat makes breathing harder.
