呼吸中枢

Purpose Medulla plays an important role in the generation of respiratory rhythm.

目的延髓是基本呼吸中枢的所在部位，在呼吸节律的产生过程中发挥着重要的作用。

This method is more accurate than the conventional ventilatory volume approach and more comprehensive than EMG of diaphragm. It can be used to measure respiratory regulation function in normal and morbid state, and in the study of apneustic center chemical sensitivity and output variable under chemical and mechanical load.

该方法比通常使用的通气量法准确，比心膈肌电图法反映全面，可广泛应用于人在正常和疾病状况下呼吸调节功能的测量，也可用于化学性及机械性负荷条件下对呼吸中枢化学敏感性及输出变量变化的研究。

The preliminary localization of lethal lesions in in-jured brain-stem indicated that,lesions in the neural structure concerning the respira-tory center and cardiovascular center might be the cause of death,which were prin-cipally on or close to the line linking the posterior angle of fourth ventricle at thedorsal surface and interpeduncular fossa at the ventral side.

脑干损伤致死性病变的初步定位提示，第四脑室下角与脚间窝之间的连线及附近的神经结构受损可能是机体死亡的原因。根据文献，此部位与机体的呼吸中枢和心血管中枢有关。

Nikethamide therapy in 15 patients with respiratory failure of chronic obstructive pulmonary disease and 8 dogs with increased airway and elastic resistance was clinically and experimentally studied.

尼可刹米能兴奋呼吸中枢、刺激通气，是治疗慢性阻塞性肺病失代偿呼吸衰竭的常用药物'。

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。

Objective To understand the relationship between effects of excite respiratory in locus coerulus complex nucleus and respiratory center of truncus encephalicus.

目的 ：探讨蓝斑复合核的呼吸兴奋效应与脑干呼吸中枢的关系。方法：本实验采用脑内核团微量注射的方法。

Howeer, the respiratory center id depressed and hypoxia is the principal stimulus for respiration.

但是当其超过65mmHg，呼吸中枢就会受到抑制，而低氧则成为刺激呼吸的主要因素。

Except for inspiration inhibition reflex,lung inflation might have another effect on respiratory center var vagus.

除吸气抑制反射外，肺充气通过迷走神经对呼吸中枢可能产生了另一种作用，其作用效果主要体现在呼吸周期的改变上。

This product is used with caution in persons dependent on opioids, the sense of disorder of unknown etiology, respiratory center and respiratory dysfunction, increased intracranial pressure without artificial respiration equipment and 1-year-old infants.

本品慎用于阿片类药依赖者、病因不明的意识紊乱、呼吸中枢和呼吸功能紊乱、颅压增高而无人工呼吸设备的情况及1岁以下婴小宝宝。

The central respiratory chemoreceptors that is widely distributed in medulla oblongata can adjust the excitability of the neurons located in respiratory center of brain stem by sensing the changes of pH and the concentration of CO2 in brain, therefore , it plays an important role in keeping acid-base balance rapidly and maintaining homeostasis in vivo.

脑内pH和CO2的变化通过中枢化学感受器(central chemoreceptors，CRCs)调节脑干呼吸中枢的兴奋性，其在快速调节机体酸碱平衡以及内环境稳定的过程中发挥着重要作用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
