measure Lung function - Spirometry
Study: Generation R Mode of collection: MeasurementsAndTests Biological sample/measurement Available measurements: Generation R 9-10 years 13-14 yearsLung function was measured by spirometry. Measures included FEV1, forced vital capacity (FVC), FEV1/FVC ratio, and forced expiratory flow at 75% of FVC (FEF75).Created October 17, 2024 • Updated October 20, 2024 -
measure Airway inflammation and airway resistance
Study: Generation R Mode of collection: MeasurementsAndTests Biological sample/measurement Available measurements: Generation R 5-6 yearsAirway interrupter resistance (Rint) was measured in kilo-pascals per liter during tidal expiration, with occlusion of the airway at peak expiratory flow. Fractional exhaled nitric oxide (FeNO) in parts per billion (ppb) was measured using the NIOX chemiluminescence analyzer.Created October 17, 2024 • Updated October 20, 2024
