Spirometry with bronchodilator reversibility test

Spirometry with Bronchodilator Test

The purpose of spirometry is to assess lung function, measuring the volume of air inhaled and exhaled, and the speed of airflow through the lungs and bronchi.

The spirometry and bronchodilator test is performed before and after the administration of a bronchodilator (in a dose determined by a doctor) to assess the reversibility of bronchial obstruction – a condition in which the airways narrow, making it difficult for air to flow.

The bronchodilator test is painless and non-invasive but requires close cooperation between the patient and the medical staff. The test takes approximately 40 minutes.

Indications for spirometry and bronchodilator testing:

• Diagnosing asthma and differentiating it from other bronchial diseases
• Monitoring the progression of bronchial asthma
• Assessing lung function in cases of chronic obstructive pulmonary disease (COPD)
• Planning appropriate treatment
• Chronic cough with significant sputum production
• Recurring respiratory infections
• Wheezing

Contraindications to the test:

Absolute:

• Recent heart attack or stroke
• Aortic or cerebral aneurysms
• Severe heart failure
• Uncontrolled high blood pressure
• Unstable angina pectoris
• Haemoptysis (coughing up blood) of unknown origin
• Pneumothorax
• Immediately after abdominal or chest surgery

Relative:

• Lack of cooperation or cognitive impairment
• Chest or abdominal pain
• Severe persistent cough, dizziness, or cardiac arrhythmia
• Acute infections (e.g., of the respiratory system or oral cavity)
• Nausea or vomiting

Important: Do not come for the test if you are experiencing any symptoms of infection.

A doctor's referral specifying the medication and dosage is required.

The test is intended for adults, but spirometry can also be performed on children over 10 years of age, unless otherwise directed by a physician.

How to prepare for spirometry and bronchodilator testing

• Please arrive at the testing facility 15 minutes before your scheduled appointment.
• The test must be performed at the designated medical facility specified at the time of purchase.
• Do not use any bronchodilators on the day of the test unless otherwise instructed by your doctor. Your referring physician will advise you on which medications to continue and which to discontinue, and when to stop them prior to the test.
• Avoid eating heavy meals or drinking strong coffee, tea, or cola a few hours before the test, as these beverages contain caffeine and other substances that can affect the airways.
• Refrain from smoking cigarettes, hookahs, or e-cigarettes, and avoid intoxicating substances for at least 2–4 hours (preferably 24 hours) before the test.
• Avoid intensive physical activity for at least 30 minutes before the test.
• Wear loose, comfortable clothing on the day of the test.

The doctor referring for the test will provide you with detailed preparation instructions.

What does spirometry involve?

Prior to the test, the patient’s blood pressure, heart rate, height, and weight are measured.

Spirometry consists of two stages:

• Stage one – basic spirometry: the patient sits upright on a chair, uses a special nose clip, and breathes into a mouthpiece connected to the spirometry device. The patient inhales and exhales according to the medical staff’s instructions.
• Stage two – spirometry after administering the medication: the test is repeated 15–20 minutes after the patient inhales the bronchodilator.

Results of spirometry and bronchodilator testing

Test results are available immediately after completion. Only a specialist can accurately interpret the results.
