动脉血气分析主要用于呼吸功能和酸碱平衡的诊断;动脉血氧分压(PaO_2)和二氧化碳分压(PaCO_2)可以反映肺通气和换气功能。从60年代开始,国内、外学者对尘肺的肺功能损害的研究,主要是肺通气量和一氧化碳弥散量(DLco)的换气功能等指标;并且,对这些患者的呼吸功能损害、丧失劳动能力的鉴定,也主要根据肺活量 Arterial blood gas analysis is mainly used for the diagnosis of respiratory function and acid-base balance; arterial oxygen pressure (PaO_2) and carbon dioxide partial pressure (PaCO_2) can reflect lung ventilation and ventilation functions. Since the 1960s, domestic and foreign scholars on pulmonary function impairment of pneumoconiosis, mainly lung ventilation and carbon monoxide dispersion (DLco) ventilation and other indicators; and, these patients respiratory dysfunction, loss of ability to work The identification is also based primarily on vital capacity
