“…SZEKELY et al [191] reported that a 6-MWD ,200 m before or after pulmonary rehabilitation is an excellent preoperative predictor of unacceptable post-operative mortality at 6 months, with a specificity of 84%. Similarly, a randomised controlled study by GEDDES et al [192], to evaluate the effect of LVRS in patients with emphysema, indicated that a preoperative shuttle walk test (SWT) distance ,150 m was a predictor of high peri-operative mortality.…”

“…KADIKAR et al [194] retrospectively observed the sensitivity and specificity of the 6-MWT to predict death in 145 patients who had undergone lung transplantation; a distance ,400 m appeared be an appropriate marker for listing patients for transplant. For LVRS, the threshold for a successful outcome has been reported to be ,150 m for the SWT [192] or 200 m for the 6-MWT [191].…”

Evidence-based recommendations on the clinical use of cardiopulmonary exercise testing (CPET) in lung and heart disease are presented, with reference to the assessment of exercise intolerance, prognostic assessment and the evaluation of therapeutic interventions (e.g. drugs, supplemental oxygen, exercise training). A commonly used grading system for recommendations in evidence-based guidelines was applied, with the grade of recommendation ranging from A, the highest, to D, the lowest.For symptom-limited incremental exercise, CPET indices, such as peak O 2 uptake (V9O 2 ), V9O 2 at lactate threshold, the slope of the ventilation-CO 2 output relationship and the presence of arterial O 2 desaturation, have all been shown to have power in prognostic evaluation. In addition, for assessment of interventions, the tolerable duration of symptom-limited high-intensity constant-load exercise often provides greater sensitivity to discriminate change than the classical incremental test. Field-testing paradigms (e.g. timed and shuttle walking tests) also prove valuable.In turn, these considerations allow the resolution of practical questions that often confront the clinician, such as: 1) ''When should an evaluation of exercise intolerance be sought?''; 2) ''Which particular form of test should be asked for?''; and 3) ''What cluster of variables should be selected when evaluating prognosis for a particular disease or the effect of a particular intervention?''

“…Holden et al 9 identified that a shorter distance in walking tests can help to determine morbidity, mortality and also the need for prolonged mechanical ventilation. Szekely et al 16 used 6MWT for COPD patients in the pre-operative of bullectomy and the distance had a significant correlation with hospital length of stay. According to these authors patients that walk less than 200 meters have a higher risk of postoperative death 16 .…”
