对于许多患有肺病的患者，或者是生活在高海拔的正常受试者或患有肺部疾病的患者，通常需要测量肺的气体交换率。在这些情况下，通常在诊断时进行测量，并进行后续测量以跟踪疾病的发展。测量气体交换的传统方法是使用动脉血气，通常得到动脉PO2(氧分压)、PCO2(二氧化碳分压)和pH(血液的酸碱平衡)。然而，这种测量具有例如有创性、使患者不舒服、需要技术人员、偶尔出现并发症并且昂贵等缺点。因此，测量气体交换有效率或无效率的无创方法是有价值的，其中患者对该方法具有良好的耐受性，并且该方法可以容易地重复。 It is frequently necessary to measure the efficiency of gas exchange of the lung, which is often essential in many patients with a pulmonary disease, or even normal subjects or patients with lung disease, who are living at high altitude. In such instances, it is common to make a measurement at the time of diagnosis, and perform subsequent measurements in order to follow the progress of the disease. The traditional method of measuring gas exchange is by using arterial blood gases. This typically gives the arterial PO2 (oxygen partial pressure), PCO2 (carbon dioxide partial pressure), and pH (acid base balance of blood). However, such a measurement has some disadvantages, such as being invasive, uncomfortable for the patient, requiring a technically skilled person, hav
