Breath and emotions are closely connected and that is reflected in various symptomatology in children with psychosomatic pathology. The aim of study was to estimate the psychosomatic status and ventilation function of breath using of respiratory biofeedback in children with various psychosomatic diseases.
To examine the relationship between respiration and psychological status in children with psychosomatic disorders, 20 children aged 8-12 were studied during the integrated treatment using respiratory BFB by capnography at day-care hospital. Rates of respiratory function, anxiety level and frustration reactivity were measured.
The significant decreases of anxiety level, combined with an increase in frustration tolerance, were found. Moreover, these processes were accompanied by an increase in CO2 at the end of exhalation (FetCO2) and the structure changes of breathing pattern. An internal restructuring of the respiratory cycle was observed: expiration time increased while the respiration rate remained unchanged.
Whereas hyperventilation syndrome diagnosis in children should be focused mainly on FetCO2 and respiration rate indices, to identify other forms of functional respiratory disorders it is necessary to control the respiratory cycle data, among them the exhalation duration particularly.
