The function of external respiration is a diagnostic method developed to assess the state of the human respiratory organs, their functionality, and to obtain speed and volume indicators.

Function of external respiration (PFR)

The function of external respiration is a diagnostic method developed to assess the state of the human respiratory organs, their functionality, to obtain speed and volume indicators. When performing various respiratory actions, graphic registration of characteristics and further processing by a special program are performed.

What the study shows

The analysis makes it possible:

• Determine the causes, degree and types of violations of the functionality of the respiratory system;
• Assign a course of therapeutic measures;
• Evaluate the effectiveness of treatment;
• To identify the possibility of pathology reversibility against the background of taking bronchodilators;
• Track the dynamics of changes. The study of the function of external respiration is the most informative method for diagnosing lung diseases, which includes two main procedures.
• Spirography – fixing changes in the amount of inhaled and exhaled air.
• Pneumotachography is a continuous recording of the volume and speed of air flow in different breathing modes. The most indicative is the graph constructed during the formed exhalation.

The combination of the two methods listed above is called spirometry.

Indications for FVD

Diagnosis is prescribed for suspected pathological changes in respiratory function and the presence of concomitant symptoms:

• Dyspnea;
• Chest pain:
• Protracted cough for a long time.

The purpose of the research is:

• Obtaining data on the impact of pulmonary pathologies on respiratory function;
• Identification of patients with a high risk of developing pathology – in many cases, these are smokers and persons in contact with harmful substances by occupation;
• Control of the course of lung diseases;
• Examination of the FDV in determining the ability to work;
• Examination before the operation;
• Selection of drugs that expand the bronchi for the course of treatment.

Spirometry shows not only the degree of respiratory dysfunction, but also allows you to:

• Identify the affected area;
• Determine the rate of progression of the pathological process;
• Select the best treatment options.

A therapist, an allergist or a pulmonologist can refer patients to the study.

Contraindications

Contraindication to the diagnosis of the function of external respiration may be:

• Severe respiratory failure.
• Recent heart attack or stroke.
• Bulges in the walls of the arteries or aorta.
• High blood pressure;
• Pregnancy;
• Epilepsy.

Study preparation

• Diagnosis is carried out on an empty stomach.
• Before studying, the day can not smoke, drink alcoholic beverages, strong tea or coffee.
• Immediately before the procedure, you need to relax and calmly sit for half an hour.
• Clothes should not shy movements.
• It is important to agree in advance the reception of drugs that influence the work of the lungs.
• When using the inhaler should have it at hand.

How the study is carried out

Fix the growth and weight of the patient. The doctor clarifies how to breathe in which sequence. The spirometer constantly fixes the amount of exhaled and inhaled air. The patient clamp the nose and propose several actions.

1. To determine the indicators in conventional breathing, you need:

• Breathe deeply;
• Hold the breath;
• Exhale evenly and calmly.

2. Actions are repeated by conducting an exhalation with an effort – receive a backup amount of exhalation for calculating the lungs life tank.

3. The patient is inhaled with an effort (to obtain an indicator of the forced lung life capacity).

Each of these actions is performed several times. Allergologist analyzes the information obtained and conclude.

Diagnosis with bronchodiolitic

Broncholic is a drug that expanding bronchi. The study passes in the traditional way, but the indicators are fixed after inhalation of aerosol bronchophy.

The results allow you to determine the presence of bronchial spasms and appoint optimal preparations for their expansion. Health and discomfort are missing. It takes twice as much time than with traditional diagnostics.

Decoding received information

The results of spirometry are evaluated by several main indicators obtained in conventional and forced breathing. If the bronchial passability is reduced, the reason for the changes occurred is determined.

Where to do FVD

The diagnosis of external respiratory function can be made in Moscow, in the wound clinic. Perform diagnostics Qualified specialists. Work is carried out on the most modern equipment using advanced diagnostic and therapeutic development.
