Estimation of the diaphragm electric stimulation influence on breath perception in patients and healthy persons

Abstract

The once-only and course use of transcutaneous diaphragm electric stimulation (ESD) caused the significant improvement of breath perception without intra pulmonary resistance changes in patients with chronic obstructive bronchitis (COB), bronchial asthma (BA), and in healthy persons. Berodual inhalations after ESD caused the further improvement of breath perception in patients with COB, BA, and in healthy persons due to its broncholitic effect. Using the original method, the breath effect of ESD was evaluated which was more durating in the cxaminated subjects during both the once-only and course use of ESD. Due to psychologic restrictions noted in patients with COB and BA, it is more preferably for dispnoe level evaluation to use the visual analog scale than the Borg one.
