Validation of Quark CPET versus "First Principles" Metabolic Calibrator

Posted in Quark CPET, Scientific

cardio pulmonary exercise test

COSMED's Quark CPET has been validated against a “first principles” metabolic calibrator capable of delivering cyclic air flows of known tidal volume, frequency and gas makeup.

“First principles” systems are advantageous in validation testing because their calibration is based solely on easily measured and verified quantities such as length and time (See: Gore CJ, Catcheside PG, French SN, Bennett JM, Laforgia J. Automated VO2max calibrator for open-circuit indirect calorimetry systems. Med Sci Sports Exerc 1997; 29(8):1095-1103).
