An invasive cardiopulmonary exercise test or iCPET is an invasive cardiopulmonary exercise test used to measure a number of factors including exertion intolerance and exercise capacity. An ICPET allows for cardiovascular, respiratory (breathing), and metabolic functions to be assessed during exercise.[1] It is not used as a diagnostic test for ME/CFS.

Differences from a cardiopulmonary exercise test[edit | edit source]

An invasive CPET differs from a non-invasive CPET in that two catheters (thin tubes) are inserted into veins and kept in place during the exercise test to provide additional information, and may be used to withdraw some blood.

One catheter is placed in a large vein, usually in the arm, neck or below the collarbone, and used to take measurement from the pulmonary artery by using the tube to pass a balloon down the artery,[2] and a second catheter is placed in the radial artery of one arm.[1] This adds additional risks compared to a noninvasive CPET.[2]

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.

ME/CFS - An acronym that combines myalgic encephalomyelitis with chronic fatigue syndrome. Sometimes they are combined because people have trouble distinguishing one from the other. Sometimes they are combined because people see them as synonyms of each other.
