The Periodic Fitness Evaluation (PFE) with Oxygen Uptake Measurement (OUM) was developed to demonstrate the capability of crewmembers to perform periodic fitness evaluations (PFE) with continuous oxygen consumption measurements within 14 days after arrival on ISS, and once monthly during routine PFEs.

Once the capability of the Pulmonary Function System (PFS) to perform PFEs is verified, crewmembers will be able to integrate their monthly PFE with oxygen consumption measurements to fulfil the requirement for cardiovascular fitness evaluations during long-duration space flight.
