Khozrevanidze Clinic uses high-precision spirometric devices, international guidelines (ATS/ERS), specially trained staff, and pays great attention to proper interpretation of results. This is why spirometry performed at the clinic is a reliable tool both for diagnosis and for disease monitoring.

What is Spirometry?

Spirometry measures:
• How much air a person can inhale and exhale (lung volumes)
• How fast the air is exhaled (lung dynamics)
• Whether the small and large bronchi are open or narrowed
• How the respiratory system responds to a bronchodilator (asthma diagnosis)

Scientifically, the test calculates parameters such as:
• FVC (Forced Vital Capacity) – the total volume of forcibly exhaled air
• FEV₁ (Forced Expiratory Volume in 1 second) – the volume exhaled in the first second
• FEV₁/FVC ratio – the main index for detecting obstruction
• PEF (Peak Expiratory Flow) – peak exhalation speed
• FEF25–75 – average exhalation flow rate, important for evaluating small airways

These data are essential not only for diagnosis but also for assessing treatment effectiveness.Who Needs Spirometry – Main Indications

Spirometry is recommended both when symptoms are present and for preventive evaluation.

At Khozrevanidze Clinic, the test is performed for:

Patients with respiratory symptoms

• Shortness of breath
• Cough (chronic or intermittent)
• Wheezing
• Night awakenings due to breathing difficulty
• Cough during physical exertion

For diagnosis of diseases

• Asthma
• Chronic Obstructive Pulmonary Disease (COPD)
• Emphysema
• Chronic bronchitis
• Restrictive diseases (pulmonary fibrosis, torso deformities, neuromuscular disorders)

For prevention

• Smokers and former smokers
• People working in dusty or toxic environments
• Athletes (respiratory function assessment and load control)

Preoperative evaluation

Spirometry is necessary before general anesthesia to assess lung reserve.

How Spirometry Is Performed at Khozrevanidze Clinic

The procedure fully follows ATS/ERS 2019 standards.

1. Preparation

The patient must follow these instructions:
• Avoid smoking for 2 hours beforehand
• Avoid heavy meals 1–2 hours before the test
• Inform the doctor if using asthma inhalers

2. Position and instruction

The patient sits or stands upright, wears a nose clip, and breathes through a mouthpiece.

The respiratory therapist explains:
• How to inhale maximally
• How to exhale quickly, forcefully, and completely
• How many times the procedure must be repeated

3. Measurement

The device records all respiratory parameters in real time.
Usually 3–5 attempts are performed to ensure reliable data.

4. If needed – Bronchodilation test

The patient uses a fast-acting bronchodilator. After 15–20 minutes, spirometry is repeated.
This test is essential for diagnosing asthma.

Advantages of Spirometry at Khozrevanidze Clinic

1. Accuracy and modern technology

The clinic uses highly sensitive electronic spirometers that ensure:
• Precise flow and volume measurement
• Automatic error detection
• Automatic comparison with international norms

2. Highly qualified specialists

Spirometry is performed and interpreted by physicians specialized in:
• Pulmonology
• Allergology
• Respiratory physiology

3. Detailed, understandable report

The patient receives:
• A detailed, scientifically based report
• Results explained in patient-friendly language
• Recommendations for treatment or further evaluation

4. High safety standards

The respiratory load is minimal; the procedure is completely safe even for pregnant women.

How to Read the Results — A Simple Explanation Behind the Numbers

• FEV₁ — the “one-second strength” of the lungs
 Low values → the lungs release air slowly → bronchial narrowing.

• FVC — the full capacity of the lungs
 Low values indicate reduced volume (fibrosis, weakness, restriction).

• FEV₁/FVC — obstruction marker
 Low ratio = asthma, COPD, or other bronchial obstruction.

• Bronchodilator response
 If FEV₁ improves significantly after inhalation → asthma is almost confirmed.

Why Is Spirometry Important?

• Provides an accurate diagnosis quickly

Many people have cough, shortness of breath, or chest heaviness without knowing the cause.
Spirometry clarifies it within minutes.

• Controls treatment effectiveness

Proper selection of inhalers, bronchodilators, and anti-inflammatory therapy depends on spirometry.

• Early detection of lung damage in smokers

Changes often begin before symptoms appear.

• Essential for managing asthma and COPD

These diseases cannot be properly controlled without spirometry.

Spirometry at Khozrevanidze Clinic combines:
Scientific accuracy + modern technology + patient-oriented explanation + professional specialists.
The test is fast, safe, informative, and critically important both for diagnosis and for planning optimal treatment.
