Impedance pneumography

Impedance pneumography is a diagnostic method based on recording fluctuations in the electrical resistance of the cross section of the patient's chest. This method is used to assess the condition of the lungs and airways.

Impedance pneumography allows you to determine the volume of the lungs, the speed of air flow in them, and also identify breathing disorders such as shortness of breath, cough, wheezing, etc.

To carry out impedance pneumography, a special device is used - a pneumograph. It consists of two electrodes that are installed on the patient's chest and a recording device. During the study, the patient breathes normally, and the pneumograph records changes in electrical resistance between the electrodes.

The results of impedance pneumography make it possible to assess the condition of the patient’s respiratory system and identify possible diseases. For example, an increase in resistance may indicate the presence of airway obstruction, and a decrease in resistance may indicate the presence of pulmonary insufficiency.

Thus, impedance pneumography is an effective method for diagnosing diseases of the respiratory tract and lungs. It allows you to identify breathing problems at an early stage and begin treatment in a timely manner.

Pneumography is one of the methods for studying the lungs, allowing one to assess the functional state of the lungs, bronchi and their walls. Pneumography is used in combination with other examination methods (x-rays, tomography) to make a more accurate diagnosis.

Pneumography and impedance pneumography. The latter is based on measuring the impedance of the chest walls to determine the presence of diffuse disorders. This requires special sensors and equipment, so this method is not used very often.
