FVC-3000肺活量計(jì)檢測儀,FVC-3000肺活量儀測定儀
空氣“流量”是診斷當(dāng)今兩種最主要的呼吸系統(tǒng)疾病的決定因素。哮喘和COPD。但是，標(biāo)準(zhǔn)的肺活量測定儀校準(zhǔn)注射器只能準(zhǔn)確地驗(yàn)證其體積！認(rèn)識(shí)到這一點(diǎn)，美國胸科學(xué)會(huì)和社會(huì)保障殘疾標(biāo)準(zhǔn)現(xiàn)在建議通過以三種不同的速率改變標(biāo)準(zhǔn)的3升容量注射器的注射時(shí)間來檢查肺量計(jì)線性和流速準(zhǔn)確性。0.5秒，6秒，介于兩者之間。盡管這是對(duì)先前建議的改進(jìn)，但這是一種不精確且耗時(shí)的方法，需要秒表。結(jié)果，很少有人遵循這些建議。

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 stopwatch. 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!
