Experimenteel: Calibre First Sequence
Participants undergo cardiopulmonary exercise testing using the investigational Calibre device during Visit 1, followed by testing with the COSMED Quark CPET reference system during Visit 2 (at least 2 days later).
|
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.
|
|
Experimenteel: COSMED First Sequence
Participants undergo cardiopulmonary exercise testing using the COSMED Quark CPET reference system during Visit 1, followed by testing with the investigational Calibre device during Visit 2 (at least 2 days later).
|
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.
