| Abstract: | The basic indices of the cardiorespiratory system function, gas exchange, regional pulmonary functions have been studied. It is stated that a group of children with a higher level of oxygen consumption (hyperergic type) as against a control group is characterized by disorder in permeability of terminal branches of a bronchial tree, by the development of acute obstructive emphysema, increase in alveolar ventilation with relative decrease in minute blood volume, arterial hypoxemia with possible emergence of tissue hypoxia. A decrease in permeability of large bronchi were observed in a group of children with a low level of oxygen consumption (hypoergic type). Due to this decrease the hypoventilation zones appeared. It caused the development of arterial hypoxemia, but a risk of the tissue hypoxia emergence was insignificant. |
