【系统影响】心脏和呼吸暂停,使向人体组织输送氧气的有效活动停止。由此产生的立即影响与讨论休克时所述情况相同(见§43)。儿茶酚胺释出,促使末梢血管收缩,以牺牲皮肤、肌肉和肾血流,保存进入心脏和脑的流血。如无氧,组织代谢即以无氧方式进行,而有乳酸生成,后者是无氧糖酵解的副产物,引起系统性代谢性酸中毒。酸中毒的程度主要即由氧的供、需平衡如何而 Systemic Effects Heart and apnea halt effective delivery of oxygen to human tissues. The immediate effect is the same as when discussing shock (see §43). Catecholamine release, to promote peripheral blood vessels to sacrifice skin, muscle and renal blood flow, save the bleeding into the heart and brain. In the absence of oxygen, tissue metabolism is performed anaerobically and lactate is produced, which is a by-product of anaerobic glycolysis, causing systemic metabolic acidosis. The degree of acidosis is mainly due to the supply of oxygen, how to balance it
