The role of the thoracic and abdominal components of the respiratory system during hyperventilation combined with chemoreceptor stimulation of various intensities

Changes in the thoracic and abdominal components of the respiratory system were studied in ten males in the standing position during voluntary hyperventilation during normocapnia, hypercapnia, and hypocapnia. Voluntary hyperventilation was shown to be based mainly on the thoracic component. Its inte...

Summary:Changes in the thoracic and abdominal components of the respiratory system were studied in ten males in the standing position during voluntary hyperventilation during normocapnia, hypercapnia, and hypocapnia. Voluntary hyperventilation was shown to be based mainly on the thoracic component. Its intensity increased during hypercapnia and decreased during hypocapnia, which is evidence of the additivity of the volitional and chemoreceptor stimuli of breathing.
