Reproducibility of lung volume measurements

摘要: Test reproducibility is an important consideration when interpreting results and should be set as a goal during data collection. Reproducibility criteria may need to different for subject groups are instrument procedure-dependent. Ideally, the within-subject variability each lung volume measurement technique used established laboratory. These values also group (age disease). At minimum, test monitored controlled laboratory define their between-day of measurements on at least one "reference" from ongoing periodic (e.g., weekly or monthly) part laboratory's quality control programme. For plethysmographic functional residual capacity (FRC)pleth multiple determinations corresponding probably justified.
