Determination of the anaerobic threshold in the pre-operative assessment clinic: inter-observer measurement error

摘要: Summary The variability between observers in the interpretation of cardiopulmonary exercise tests may impact upon clinical decision making and affect risk stratification peri-operative management a patient. purpose this study was to quantify inter-reader determination anaerobic threshold (V-slope method). A series 21 from patients attending surgical pre-operative assessment clinic were read independently by nine experienced clinicians regularly involved making. grand mean for 10.5 ml O2.kg body mass )1 .min . technical error measurement 8.1% (circa 0.9 ml.kg ; 90% confidence interval, 7.4‐8.9%). absolute difference readers 4.5% with typical random 6.5% (6.0‐7.2%). We conclude that inter-observer determining is acceptable.
