Vitalograph Lung Age将患者的FEV1与预测的正常值进行比较，以计算患者的“肺功量”。与患者的年龄年龄相比的高肺时代可以说明持续吸烟对肺功能的可能产生的负面影响，并鼓励戒烟。早期识别FEV1的减少可以提供在吸烟最有效的肺部肺部肺部已经受到肺的损伤的预警。

Protect your patient and your testing instruments with the VBMax™ Pulmonary Function Filter. VBMax™ provides a high degree of protection for the patient as well as your testing equipment, while its low resistance allows for accurate testing results.
Independent laboratory tests have verified that this pulmonary function filter is highly effective. VBMax™ consistently filters out more than 99.999% of bacteria and 99.99% of viruses. At the same time, VBMax™ easily surpasses published ATS recommendations for flow resistance in pulmonary function instrumentation, which suggest resistance should be below 1.5 cm H2O/L/sec at flow rates of 14 L/sec.
