FVC-3000肺活量计检测仪,FVC-3000肺活量仪测定仪
空气“流量”是诊断当两种主要的呼吸系统疾病的决定因素。哮喘和COPD。但是，标准的肺活量测定仪校准注射器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残疾标准现在建议通过以三种不同的速率改变标准的3升容量注射器的注射时间来检查肺量计线性和流速准确性。0.5，6，介于两者之间。尽管这是对先建议的改进，但这是一种不精确且耗时的方法，需要表。结果，很少有人遵循这些建议。

Air “flow” is the determining factor in the diagnosis of today’s two most predominant respiratory diseases; asthma ａnd COPD. Yet, standard spirometry calibration syringes can only accurately validate for volume! Recognizing this, the American Thoracic Society ａnd the Social Security Disability standards now recommend checking spirometric linearity ａnd flow rate accuracy by varying injection times of a standard 3-liter volumetric syringe at three different rates; 0.5 seconds, 6 seconds, ａnd somewhere in between. Although this is an improvement over previous recommendations, it is an inaccurate ａnd time-consuming approach requiring a swatch. As a consequence, very few people follow these recommendations.

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!
