respiratory center

Respiratory movement, known as a kind of rhythmic activity, can be regulated by respiratory center.

呼吸运动是一种节律性的活动, 受呼吸中枢的调节.

Nikethamide still had the effect of stimulation of respiratory center and enhancement of ventilation even though chronic pulmonary obstruction with CO_2 retention was present.

但由于慢阻肺呼吸运动机械阻力增加、通气量的提高，将促使机体代谢率上升，可抵消兴奋呼吸所起的缓解缺氧和CO2潴留的积极作用，甚至适得其反。

The lung functions after treatment showed various degrees of improvement. Nikethamide still had the effect of stimulation of respiratory center and enhancement of ventilation even though chronic pulmonary obstruction with CO_2 retention was present.

临床观察和动物实验结果显示，慢阻肺伴CO2潴留时，尼可刹米仍可兴奋呼吸中枢、提高通气量。

from the results obtained, it seemed likely that the hyperpnea induced by intravenous injection of ammonium chloride was duo to direct excitation of the respiratory center by increase in hydrogen ion concentration of the blood, and that the peripheral chemoreceptors played no significant role in this effect.

氯化铵所致的呼吸增强，可能主要是由于血浆中氢离子增加对呼吸中枢的直接刺激作用，外周化学感受器在这方面不起重大作用。
