Method Validation of Cardiopulmonary Exercise Testing: Intra- and Inter-Device Comparisons Across Four Metabolic Carts

Key Result

Under standardized conditions, four tested metabolic carts showed comparable intra-device reliability and inter-device measurement consistency.

Key Points

• The aim is to validate the performance of different metabolic carts during cardiopulmonary exercise testing.
• Conducted tests under standardized conditions on multiple metabolic carts.
• Measured the performance of each cart for reliability and comparability.
• Performed intra-device and inter-device comparison analyses.
• All tested metabolic carts demonstrated reliable performance within devices.
• Significant comparability was found between different metabolic carts.
• Values yielded showed minimal variation across the devices tested.
