Aim: The prevalence of airway obstruction varies widely with the definition used. Spirometry Values • FVC: Forced vital capacity: the volume of air that can be maximally forcefully exhaled. This calculator will compute the normal values for 16 different references. Spirometry is a powerful tool that can be used to detect, follow, and manage patients with lung disorders. To see Percent Predicted, you must enter observed FVC, FEV1, and FEF25-75% values in the appropriate boxes. Spirometry Reference Value Calculator. Loge (PEF)= 0.544 x loge (age) - 0.0151 x (age) - 74.7/ (height) + 5.48.

John L. Hankinson, PhD, is a biomedical engineer and consultant. Female. The primary signal measured in spirometry may be volume or flow. Some references should be pointed out as they were highlighted as "recommended" by the European Respiratory Society (ERS Quanjer 1993), and the American Thoracic Society (NHANESIII, by Hankinson et al. The paediatric calculation (for ages below 15 years) is taken from Lung Function by J E Coates (Fourth Edition): PEF = 455 x (height/100)-332. 28 This study showed that the predicted values for FEV 1, FVC and FEV 1 /FVC produced by the GLI 2012 equations were similar to the equations from Wang et al. Spirometry (FEV 1, forced vital capacity [FVC], and FEV 1 /FVC) should be performed in a non‐acute setting before and after bronchodilator administration. information, including an The administrative variable SPDBRONC indicates whether the participant was considered eligible for Bronchodilator 2nd Test Spirometry. KEYWORDS: Peak expiratory flow, spirometry, spirometry standardisation, spirometry technique, spirometry traning, ventilation BACKGROUND Spirometry is a physiological test that measures how an individual inhales or exhales volumes of air as a function of time. Spirometry is the measurement of lung volumes and airflow.

(1993). Reference Value Calculator. These NHANES 1999 regressions are recommended for ethnically appropriate individuals by the ATS/ERS Task Force:2005 ‘Standardization of Lung Function Testing’. If spirometry shows airflow obstruction or you suspect a diagnosis of asthma, consider proceeding with reversibility testing.. a. Reversibility tests involves performing spirometry before and after bronchodilator therapy and can help distinguish between asthma and COPD (note that spirometry may be normal in stable asthma). Spirometry is a straightforward test and is generally considered very safe. You can get a general idea of your predicted normal value with a spirometry calculator.
