FIELD: medicine. SUBSTANCE: method involves determining the degree the diaphragm participates in breathing action by recording breathing excursions of chest wall and intragastric pressure at the same time. Breathing wave is separated as regular changes of intragastric pressure correlated to breathing within the limits of 1-10 cm of aqueous column. The breathing wave is correlated to respiration phases. Breathing wave peak corresponding in time to inhalation start, normal diaphragm and abdomen contribution to breathing action is diagnosed. Breathing wave decrease being coincident with inhalation, diaphragm and viscera state disorder is to be diagnosed. Manometric evaluation of diaphragm contraction activity during respiration enables clinical application of the symptom of abdomen participation in breathing to be essentially widened for revealing diaphragm and viscera state disorders before marked clinical symptoms become available. EFFECT: enhanced effectiveness of treatment; accelerated treatment course; high reliability and sensitivity of diagnosis. 3 dwg
