空气“流量”是诊断当今两种主要的呼吸系统疾病的决定因素。COPD。但是，标准的肺活量测定仪校准只能准确地验证其体积！认识到这一点，美国胸科学会和社会保障标准现在建议通过以三种不同的速率改变标准的3升容量泵的时间来检查肺量计线性和流速准确性。0.5秒，6秒，介于两者之间。尽管这是对先前建议的改进，但这是一种不准确且耗时的方法，需要秒表。结果，很少有人遵循这些建议。
FVC-3000肺活量仪测定仪由美国Jones生产与研发！

FVC-3000肺活量计检测仪,FVC-3000肺活量仪测定仪 不仅可以验证FVC参数，还可以验证FEV1，FEF 25-75，PEFR和瞬时呼气流速（FEF25，FEF50和FEF75）以及FIVC。现在，您可以在1.5到3升的体积范围内以1.5毫升的数字增量从零到每秒12升验证您的肺功能设备的流速精度！

Air “flow” is the determining factor in the diagnosis of today’s two most predomina*espiratory diseases; asthma and COPD. Yet, standa*pirometry calibrati*yringes can only accurately validate for volume! Recognizing this, the American Thoracic Society and the Social Security Disability standa* now recommend checking spirometric linearity and flow rate accuracy by varying injection times of a standard 3-liter volumetric syringe at three differe*ates; 0.5 seconds, 6 seconds, and somewhere in between. Although it is an improveme*ver previous recommendati*, it is an inaccurate and time-c*uming approach requiring a stopwatch. As a c*equence, very few people follow these recommendati*.

The digital Flow-Volume Calibrator^® surpasses these requirements by providing the ability to validate not only the FVC parameter, but also the FEV1, FEF 25-75, PEFR and instantaneous expiratory flow rates (FEF25, FEF50, and FEF75), as well as the FIVC. You can now verify the flow rate accuracy of your pulmonary function device from zero to twelve liters per second anywhere in the volumetric range of zero to three liters in digital increments of 1.5 milliliters!
