Spirography (Spirometry)

Spirography (Spirometry)

Spirography is one of the most important methods for assessing lung (external respiratory) function; it helps detect pulmonary diseases at early stages. The examination is quick, painless, and informative.

Spirography (Spirometry)

What is spirography?

Spirography (or spirometry) is a method for studying the function of external respiration. Different medical institutions may use different names, but they refer to the same examination.

The primary goal of spirography is to evaluate how the lungs and airways work and to detect impairments of external respiratory function in patients with respiratory diseases. Spirometry is one of the «gold standards» for diagnosing bronchial asthma because it allows detection of bronchial obstruction and assessment of whether it is reversible. Sometimes a person feels no breathing problems, yet spirometry already shows impaired lung function. That is why the test results help identify asthma before pronounced symptoms appear and start treatment in a timely manner.

What does spirography show?

Spirography shows how external respiratory function works and how well the lungs perform their job. First and foremost, the test helps detect the presence of bronchial obstruction and determine whether it is reversible. Spirography also allows assessment of treatment effectiveness: if measurements improve after therapy is prescribed, this indicates that the treatment was appropriate and the disease is responding positively. The test can reveal impairments even when a person has no complaints, which makes it possible to adjust treatment in a timely manner.

Spirography helps determine the degree of changes in chronic obstructive pulmonary disease (COPD), which is important for selecting the correct treatment strategy. Spirometry results are also used in preoperative evaluation to assess the functional state of the respiratory system and to reduce risks during anesthesia.

Indications and contraindications for spirography

Like any procedure, spirography has its indications and contraindications.

Indications for spirography include:

  • suspected bronchial asthma;
  • confirmation of bronchial asthma diagnosis and determination of reversibility of bronchial obstruction;
  • monitoring the effectiveness of bronchial asthma treatment — the test allows assessment of whether parameters improve under baseline therapy;
  • diagnosis of chronic obstructive pulmonary disease (COPD);
  • evaluation of the degree of impairment of lung function to select appropriate treatment;
  • prolonged cough and cough with sputum production;
  • shortness of breath at rest or during physical exertion;
  • chest discomfort;
  • lung examination after COVID-19;
  • preoperative assessment to evaluate respiratory system function.

Spirography is a safe method and well tolerated by most patients. However, performing it temporarily increases intrathoracic, intra-abdominal, and intracranial pressure. Therefore, in some cases the examination is carried out with caution.

Relative contraindications for spirography include:

  • cardiovascular diseases such as acute myocardial infarction (within the first week), elevated or low arterial blood pressure, arrhythmia, decompensated heart failure;
  • conditions associated with increased intracranial or intraocular pressure, for example, cerebral aneurysm;
  • surgeries on the paranasal sinuses, middle ear, or eyes performed within the past week;
  • abdominal, thoracic, or neurosurgical operations performed less than four weeks ago;
  • recent concussion with persistent symptoms;
  • pneumothorax;
  • late-term pregnancy.

After examining the patient, the doctor determines whether spirometry can be performed in the specific case.

Where can spirography be done?

Spirography is a widely used diagnostic method that has been employed for many years. According to current medical protocols, general practitioners, family doctors, and pediatricians should have the skills to perform spirography.

However, it is not enough merely to perform the test and interpret the results. They must also be correlated with the patient’s clinical picture and medical history. For this reason, the interpretation of spirography results and the prescription of treatment should be done by a specialist — a pulmonologist or an allergist. At the VIRTUS clinic, consultations are led by a pulmonologist with over 33 years of experience — Viktor Yakovych Stukanov. The doctor performs spirometry and prescribes treatment on an individual basis.

Frequently Asked Questions

Which diseases can be detected using spirography?

Spirography is one of the most important methods for diagnosing respiratory system diseases, since it can reveal impaired lung function even when the patient does not yet have pronounced symptoms. The test is used to diagnose bronchial asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis, pulmonary fibrosis, and other respiratory system disorders.

Which doctor performs spirography?

A pulmonologist can properly perform spirography and correlate its results with the patient’s medical history.

How much does spirography cost in Odesa?

The cost of spirography in Odesa depends on the type of test. Standard spirography is less expensive, while a test with a bronchodilator challenge is more costly because it includes additional drug administration and repeat measurements. At VIRTUS the examinations are performed on modern equipment, and the results are analyzed by an experienced pulmonologist.

Is spirography painful?

Spirography is a painless procedure. However, during the test patients may experience weakness, dizziness, fatigue, or a brief cough triggered by the intensive inhalation. These symptoms usually pass quickly. If the patient has a history of myocardial infarction, a temporary increase in heart rate is possible.

How long does spirography take?

The duration of the test depends on its type and takes up to 30 minutes.

Preparation for spirography

To ensure a successful examination, follow these recommendations before the test. Preparation for spirometry includes:

  • do not smoke for 6 hours before the test;
  • do not eat heavy food for 2 hours before the test;
  • avoid physical exertion for at least 30 minutes before spirometry;
  • wear clothing that does not compress the chest;
  • if possible, do not use an inhaler for six to eight hours before the test.

Also inform the doctor if you take any medications regularly and clarify whether you should take them on the day of the examination.

Stages of spirography

During spirography the patient performs specific breathing maneuvers under the supervision of a healthcare professional. The stages of performing spirometry are as follows:

  1. The patient sits with a straight back.
  2. A nose clip is applied.
  3. The patient places their lips around a mouthpiece connected to the spirometer.
  4. The patient takes the deepest possible breath and then exhales as quickly and forcefully as possible.

The test is performed three times in succession to obtain the most accurate results. Spirography for the diagnosis of bronchial asthma is conducted as follows:

  1. Perform standard spirometry. Assess the main parameters of external respiratory function.
  2. Short-acting bronchodilator test. The patient receives a bronchodilator medication.
  3. Repeat spirometry. Ten to fifteen minutes after inhaling the bronchodilator, spirometry is repeated.
  4. Compare results. The doctor compares the results of the first and second tests. If lung function measurements improve, this indicates reversibility of bronchial obstruction, which is a characteristic sign of bronchial asthma.

After the examination is completed, the doctor interprets the results obtained and, if necessary, prescribes additional tests or treatment.
