CPET- Cardiopulmonary Exercise Test: Type: cycle- cycle ergometer or treadmill (TM) using various protocols of gradually increasing power output. Stop: Pt: voluntary exhaustion. AT: % of group that had an anaerobic threshold. RER: Average maximum respiratory exchange ratio. 6 MWT- Six Minute Walk Test: Length: length of corridor in feet or Meters. Ped: pedometer, Cor: corridor but length not reported. Stop (Criteria for terminating walk): Distress: various distress criteria, O2 < 80%: O2 saturation dropping below 80%, None: Everyone completed test. NR: not reported, * some patients used O2 during the walk.
