[Tele-electrometry of the respiratory musculature in healthy subjects and patients with obstructive ling diseases].
Respiratory muscles fatigue is a common symptom typical for chronic obstructive pulmonary diseases. The authors were the first to use an original diagnostic system of distant electrometry "Briz-1" and examination techniques. The principle of the diagnostic system operation is based on a contactless measurement of magnitudes of trunk surface excursions during respiratory movements with the help of a system of electromagnetic field transducers located near the trunk. The electromagnetic field is induced by a special generator. Examination included 75 patients with chronic obstructive pulmonary diseases and 21 healthy volunteers (the norm has been elaborated). The results obtained on the diagnostic system were compared with the clinico-functional studies. The method is simple, harmless, easy for patients in terms of load, informative and allows numerous measurements. Diagnostic criteria of obstructive pulmonary diseases and diaphragm fatigue have been developed.
