[Criteria for quantitative assessment of respiratory system reactions].

In anesthetized cats and in healthy humans, lung ventilation, activity of diaphragmal motoneurons and intercostal muscles, shift of the intrathoracic pressure, inspiratory occlusional pressure, and maximal rate of the initial increase in inspiratory pressure, were studied. Depending on conditions of the respiratory system functioning, any one from among the above parameters can reflect the efferent output of the respiratory center. Each of them, however, has limitations of its own.
