In cat+s, increased resistance against breathing at the background of hyperventilation with a hypercapnic mixture reduces the 1-min ventilation. However, the bioelectric activity of the diaphragmatic nerve becomes augmented, thus indicating an increase in the respiratory center inspiratory activity. Vagotomy was followed by a decreased ventilatory response to CO2. Suppression of ventilation and augmentation of the diaphragmatic nerve activity during additional resistance against breathing in vagotomized animals were preserved on account of a considerably greater activity of the respiratory center. The data obtained suggest that, in conditions of combination of increased resistance against breathing with hypercapnia, the lungs afferent system fulfills an optimization of activity of the ventilatory apparatus.
在猫+组中，在使用高碳酸血症混合气体进行过度通气的背景下，呼吸阻力增加会降低1分钟通气量。然而，膈神经的生物电活动增强，从而表明呼吸中枢吸气活动增加。迷走神经切断术后，对二氧化碳的通气反应降低。由于呼吸中枢的活动明显增强，在迷走神经切断的动物中，在额外的呼吸阻力期间，通气抑制和膈神经活动增强得以保留。所获得的数据表明，在呼吸阻力增加与高碳酸血症相结合的情况下，肺传入系统实现了通气装置活动的优化。
