breathing screening test preparation
Informed by recognized medical guidance
Overview
A breathing screening test, often called spirometry, is a simple way to measure how well your lungs work. You breathe into a machine that records how much air you can breathe out and how fast. The test helps your doctor check for lung problems such as asthma or chronic obstructive pulmonary disease (COPD).
Key facts
- The test is painless and usually takes about 15 to 30 minutes.
- You may be asked to avoid smoking, heavy meals, and certain medications before the test – your doctor will give you specific instructions.
- You will need to give your best effort: blow out as hard and as fast as you can several times.
Breathing screening tests are very common. They are used to diagnose lung conditions and to monitor how well treatments are working.
Anyone who has symptoms like shortness of breath, chronic cough, or wheezing may be asked to have a breathing test. It is often used for people with suspected asthma or COPD, but can be helpful for many others.
Symptoms
- Severe difficulty breathing, cannot speak a sentence
- Lips or face turning blue or grey
- Sudden, intense chest pain that does not go away
- Feeling faint or losing consciousness
- ⚠Wheezing that does not improve with your usual medicine
- ⚠Coughing up blood
- ⚠Shortness of breath that gets worse over hours
- ⚠High fever with cough or difficulty breathing
Common symptoms
- Shortness of breath, especially during exercise
- A long-lasting cough (more than 3 weeks)
- Wheezing – a whistling sound when you breathe
- Coughing up mucus or phlegm
- Feeling like you cannot get enough air
Symptoms in children
- Frequent coughing, especially at night or during play
- Tiring easily during physical activities
- Noisy breathing or wheezing
- Chest tightness
Symptoms in older adults
- Gradual shortness of breath with daily activities
- Chronic cough that may be worse in the morning
- Frequent chest infections
- Unexplained tiredness
Causes
Main causes
- Breathing screening tests help find lung problems, but they do not cause them. The conditions that may lead to having this test include asthma, COPD, lung infections, or scarring of the lung tissue (pulmonary fibrosis).
- The test itself is harmless and does not cause any lung disease.
Risk factors
- Smoking or exposure to second-handed smoke
- Family history of asthma or COPD
- Workplace exposure to dust, chemicals, or fumes
- History of frequent lung infections in childhood
When to see a doctor
See a doctor urgently if:
- You have any of the emergency symptoms listed above (severe breathing trouble, blue lips, chest pain).
- Your usual inhaler or medicine is not helping you breathe better.
Book a routine appointment if:
- You have a cough that lasts more than three weeks.
- You get short of breath more easily than before.
- You have been told you have a lung condition and need to check your lung function regularly.
- Your doctor wants to monitor your response to treatment.
Diagnosis
The breathing screening test itself is a key tool for diagnosing lung conditions. Your doctor will also ask about your symptoms, medical history, and may listen to your chest with a stethoscope.
Tests that may be done
- Spirometry – the main breathing test where you blow into a tube connected to a machine.
- Peak flow meter – a small handheld device you blow into to measure how fast you can breathe out.
- Chest X-ray or CT scan to look at the lungs.
- Blood tests to check for inflammation or lung function markers.
What to expect at your appointment
On the day of the test, you will be asked to remove anything tight around your neck or chest. You will sit upright and place a soft clip on your nose. The nurse or technician will ask you to take a deep breath and then blow into the mouthpiece as hard and fast as you can. You will repeat this several times to get the best reading. The test often takes about 15 minutes. It is not painful, but you may feel a little tired or light-headed – that is normal.
Treatment
This article is about preparing for a breathing screening test, not about treating a condition. Treatment for any lung problems found by the test will depend on the diagnosis. Your doctor will discuss the best options for you.
Self-care at home
- Follow all pre-test instructions given by your doctor or the testing centre. These may include not smoking for 24 hours before the test, avoiding heavy meals, and not using certain inhalers or medications (your doctor will tell you exactly which ones).
- Wear loose, comfortable clothing that does not restrict your breathing.
- If you usually use a rescue inhaler, ask your doctor if you should bring it with you.
- Try to relax and breathe normally before the test.
Medical treatments
If the test shows a lung condition, your doctor might recommend inhalers (puffers), breathing exercises, or other medications to help open your airways. Some people may need oxygen therapy or pulmonary rehabilitation (a programme of exercise and education). Your doctor will explain the options based on your individual results.
When is surgery considered?
surgery is rarely the first treatment for lung conditions found through screening. In some cases, such as very severe COPD or certain lung diseases, a doctor may discuss lung volume reduction surgery or a lung transplant. This is only considered after many other treatments have been tried.
Living with this condition
After you have had a breathing screening test, you can go back to your normal activities right away. There is no recovery time. The results may take a few days to come back – your doctor will explain them and discuss next steps.
Lifestyle tips
- If you smoke, consider quitting – your healthcare team can help.
- Avoid lung irritants such as dust, fumes, and strong chemicals.
- Stay active with gentle exercise like walking, as recommended by your doctor.
- Use your inhalers or medications exactly as prescribed.
Diet and exercise
A balanced diet with plenty of fruits and vegetables supports overall lung health. Gentle exercise, like walking or swimming, can strengthen your breathing muscles. Always check with your doctor before starting a new exercise routine.
Mental health and emotional wellbeing
Waiting for test results can be stressful. It is normal to feel anxious or worried. Talk to your doctor or a counsellor if these feelings become overwhelming. If you have thoughts of harming yourself, call emergency services immediately.
Prevention
A breathing screening test itself does not prevent lung disease – it helps find it early. But you can reduce your risk of lung problems by not smoking, avoiding air pollution, and getting vaccinated against flu and pneumonia.
Vaccines
Flu and pneumonia vaccines can help protect your lungs from serious infections. Ask your doctor if they are right for you.
Screening programmes
Your doctor may recommend regular breathing tests if you have a long-term lung condition or if you are at high risk, such as from smoking. Screening helps catch problems early.
Complications
If left untreated
- Lung conditions that are not diagnosed can get worse over time, leading to more breathing difficulty and lower quality of life.
- Untreated asthma or COPD can lead to frequent hospital visits or emergency episodes.
Long-term outlook
Most people who have a breathing screening test find it helpful. If a lung condition is found, early treatment can often improve symptoms and slow the disease. Many people live full, active lives with proper care. The outlook is generally good when problems are caught early.
