Interventions
COSMED Quark CPET metabolic cart
FDA-cleared cardiopulmonary exercise testing (CPET) metabolic cart used as the reference comparator for measurement of respiratory gas exchange and ventilatory parameters during ramp cycle ergometry. Participants wear a facemask connected to the system for breath-by-breath measurement of oxygen consumption (VO2), carbon dioxide production (VCO2), minute ventilation (VE), anaerobic threshold, and ventilatory efficiency during maximal exercise testing.
Calibre Biometrics
Investigational wearable facemask device with integrated sensors for breath-by-breath measurement of respiratory gas exchange and ventilatory parameters during cardiopulmonary exercise testing, evaluated against the COSMED Quark CPET reference system.
