Clinical Trial: Test-Retest Reliability And Validation For End-Tidal Carbon Dioxide Measurement (PetCO2) During Rest And Low-Loaded Steady State Work Using A Portable Capnograph.

U.S., Jan. 9 -- ClinicalTrials.gov registry received information related to the study (NCT07326449) titled 'Test-Retest Reliability And Validation For End-Tidal Carbon Dioxide Measurement (PetCO2) During Rest And Low-Loaded Steady State Work Using A Portable Capnograph.' on Dec. 17, 2025.

Brief Summary: The goal of this observational study is to investigate exhaled carbon dioxide measuring during rest and low-loaded work using a portable device (capnograph) and standard of care apparatus during a cardiopulmonary exercise test (CPET) in healthy volunteers. The study aims to answer:

How reliable is exhaled end-tidal carbon dioxide measurement for an individual over time using both standard of care apparatus and a portable device during an e...
