Table 3 Mean ± standard deviation (SD) for relative flow measurements from eight untreated horses at rest (eupnoea) and during rebreathing over three consecutive days

From: Reliability of breath by breath spirometry and relative flow-time indices for pulmonary function testing in horses

  1. Each parameter represented the percent of peak flow at the appropriate relative time within each breath cycle, and was determined by analysis of three breaths on each testing day. Within day coefficients of variation (CV) were calculated across this data as a measure of repeatability. Mean values (± SD) reported below, between day CV (reproducibility), and intraclass correlation coefficients (ICC, reported with 90% confidence interval), were determined by analysis of pooled data (mean of three breaths) collected on each day of testing. Ghosted (grey) results for ICC indicate poor or moderate agreement
  2. Abbreviations: izp inspiratory flow zero to peak, ipz inspiratory flow peak to zero, expiratory flow zero to peak, epz expiratory flow peak to zero, SD standard deviation, ICC intraclass correlation coefficient, CI confidence interval
