Spirometry Test in Sharjah

What is spirometry?

Spirometry measures airflow. You take the deepest breath you can, seal your lips around a mouthpiece and blast the air out as hard and fast as possible, then keep pushing until your lungs feel completely empty. A sensor records the volume and speed of that breath and draws it as a curve on screen.

Two numbers matter most, and both are easier to understand than their names suggest:

• FEV1 (forced expiratory volume in one second) is how much air you push out in the first second. Narrowed airways slow this first burst down.
• FVC (forced vital capacity) is the total amount you blow out in the whole breath, from completely full to completely empty.

The ratio between them shows what share of your breath leaves in that first second. A low ratio points to narrowed airways, the pattern seen in asthma and COPD. A reduced total with a preserved ratio suggests the lungs are holding less air overall, which leads to fuller testing. Your results are compared with predicted values for someone of your age, height and sex, which is why your height is measured on the day.

Who needs it

Spirometry is the core test for anyone whose breathing may be affected by the airways. Your doctor may request it if you have:

• Wheeze, chest tightness or cough that comes and goes, especially at night or with dust
• Breathlessness on exertion that seems out of proportion to your fitness
• A long smoking history, including shisha, dokha or midwakh, or regular vaping
• Years of work in construction, quarrying, cleaning products, welding or other dusty trades
• Known asthma or COPD, to check control and see how treatment is working
• A planned operation, where lung reserve helps anaesthetic planning

It is also used to follow a condition over time. Repeating the test at intervals shows whether your airflow is holding steady, which is often more informative than any single reading. The department-level overview of lung conditions sits on the Pulmonology page, and ongoing care is covered on the asthma treatment and COPD management pages.

What happens

At Dar Al Kamal Hospital, Sharjah, spirometry is carried out in the pulmonology clinic. You sit upright in a chair, feet flat on the floor, and a soft clip is placed on your nose so all the air goes through the mouthpiece.

Effort decides the result, so coaching is a big part of the test. The person running it demonstrates the breath, then talks you through each attempt, often loudly and with encouragement: "breathe all the way in… blast… keep going, keep going". This is deliberate. A hesitant start, a cough, a leak around the lips or stopping early all make the reading look worse than your lungs really are. You repeat the breath several times until at least three good attempts closely agree, and the best is used.

The reliever check comes next. You then take a few puffs of a reliever inhaler through a spacer, wait a short while for it to work, and repeat the blows. A clear improvement in airflow after the reliever, called reversibility, supports asthma; airflow that stays largely the same fits better with COPD. This before-and-after comparison is the single most useful step in telling the two apart.

If the pattern needs more detail, full pulmonary function testing adds lung volumes and gas transfer. A chest X-ray through radiology may be added to look at the lungs themselves.

Preparing for it

Good preparation keeps your result accurate:

• Follow the instructions you receive at booking about pausing any inhalers beforehand, and keep your reliever with you at all times
• Avoid smoking, shisha and vaping on the day of the test
• Skip a heavy meal and vigorous exercise in the hours before
• Wear loose clothing that lets your chest and stomach move freely
• Bring all your inhalers and any previous spirometry printouts, including reports from other countries

Tell the team at booking about any recent eye, chest or abdominal surgery, a recent heart problem, or recent coughing up of blood, as the test may be timed around your recovery. During Ramadan, mention that you are fasting so the appointment and any reliever puffs can be planned with you. If a dust storm has flared your symptoms, say so on the day, since it helps the pulmonologist interpret the numbers.

Afterwards

Most people feel back to normal within moments and can drive, work and eat as usual. Some feel briefly light-headed, tired or a little coughy from the repeated forceful breaths; sitting quietly for a minute settles this.

The pulmonologist usually goes through the curve and the numbers with you at the same visit, explaining what the pattern means and whether treatment or further tests are needed. Keep a copy of your results, since comparing future tests with today's is how change is tracked.

Contact the hospital if you feel wheezy or breathless after the test and your reliever gives little relief. For severe breathlessness, blue lips or an asthma attack that is failing to respond to your reliever, call emergency services or go to the nearest emergency department.

Cost and insurance

Most UAE health insurance plans cover spirometry when a doctor requests it for symptoms or a known lung condition, and it is often done at the same visit as the consultation. Full lung function testing and imaging sometimes need pre-approval. Dar Al Kamal Hospital, Sharjah can help you confirm your cover on 06 599 7777.
