Cardiopulmonary exercise test
Cardiopulmonary exercise testing (CPET or CPEX), also referred to as a VO2 (oxygen consumption) test, is a specialized type of stress test or exercise test that measures your exercise ability. It has been used extensively to study Myalgic encephalomyelitis/Chronic fatigue syndrome and is considered a potential biomarker for the syndrome.
ME/CFS[edit | edit source]
Long COVID[edit | edit source]
In a single CPET test, Post-COVID-19 patients exhibited markedly reduced peak exercise aerobic capacity (VO2) compared to controls and impaired oxygen extraction, even in those without cardiopulmonary disease.

two-day cardiopulmonary exercise test (CPET) - A diagnostic test which involves testing an ME/CFS patient exercising on an exercise machine, while monitoring their respiration, especially oxygen consumption. This test is repeated the following day in order to confirm the patient's inability to replicate the first-day performance. This test is thought to be the most objective way to detect post-exertional malaise.
