title: Analysis of breath-by-breath exercise data from field studies.
abstract: We describe a system useful for collecting and analyzing breath-by-breath exercise test data in the field. In studies of untrained subjects, analysis of artifacts is particularly important. Our system uses pattern-recognition criteria to reject breaths if the breathing valves do not operate satisfactorily or if deviations from the calibrating baseline occur.
