The total volume of the lungs was determined by digital planimetry in 102 patients with emphysema and 33 normal controls aged between 30 and 79 years. The results were compared with the findings obtained from spirometric measurements. Mean values showed a significant relationship to age, body size and body surface. Planimetrically determined lung volume did not show a linear relationship with age, but increased after 60 years. Beyond 60 years, spirometric findings were lower because of an increase in the number of patients with emphysema. The results have shown that digital planimetry is a useful addition to spirometry.
通过数字平面测量法测定了102例年龄在30至79岁之间的肺气肿患者和33例正常对照者的肺总体积。将结果与肺活量测定法的结果进行了比较。平均值显示与年龄、体型和体表面积存在显著关系。平面测量法测定的肺容积与年龄无线性关系，但在60岁后增加。60岁以后，由于肺气肿患者数量增加，肺活量测定结果较低。结果表明，数字平面测量法是肺活量测定法的有益补充。
