The Quark CPET is a state-of-the-art meta-bolic cart for gas exchange analysis (VO 2, VCO 2) either during exercise testing or resting protocols. Its high quality components and super-fast analyzers assure unsurpassed accuracy, reliability, and real breath-by-breath analysis of pulmonary gas exchange, even at high intensity exercises.

2025年1月29日 · The stationary, cart-based COSMED Quark (COSMED, Rome, Italy) was operated in breath-by-breath mode and consisted of a bidirectional turbine (resistance: < 0.6 cmH 2 O/L/s at 14 L/s) and an optical reader for the assessment of inspired and expired gas volumes and sampling line attached to a dual gas analyzer for the assessment of fractional ...

CPET（心肺运动测试）是评估运动生理反应的理想解决方案。 其高品质组件和超快速分析仪可确保无与伦比的准确性、可靠性和真正的逐次呼吸分析，即使在高强度运动期间也是如此。

This study validated the accuracy of COSMED's Quark cardiopulmonary exercise testing (CPET) metabolic mixing chamber system in measuring metabolic factors during maximal, graded exercise testing. Subjects included 32 physically active men between the ages of 18 and 34 years. During the first test se …

When used appropriately in laboratory settings, the COSMED Quark and VO2Master Pro systems provide gas exchange and ventilatory data within an acceptable range for metabolic testing equipment that are both reliable and transferable between optimally performing devices.

2025年1月30日 · The COSMED Quark uses a bidirectional turbine and gas analyzers, while the VO2Master Pro employs a differential pressure flow sensor and an O2 analyzer. Both systems apply different standard temperature and pressure (STPD) correction factors, necessitating adjustments to ensure accurate comparisons.
