In honor of ME/CFS week, we are happy to highlight the newest tool in the fight to not only treat but also recognize chronic fatigue and related conditions: The Invasive Cardiopulmonary Exercise Test, also known as iCPET.
As those familiar with ME/CFS and other related conditions may be aware, “traditional” CPET is the gold standard for objectively measuring the limitations caused by chronic fatigue and the impact those limitations have on an individual’s ability to work. Dr. Christopher Snell and the incredible people at the Workwell Foundation have been administering (and improving) this test for years. Despite the plethora of peer-reviewed data confirming CPET’s objective effectiveness in measuring such limitations, insurers still do their best to disregard and minimize CPET.
In contrast to the CPET, which only requires being hooked up to “external” sensors, the iCPET involves the additional insertion of pulmonary artery and radial artery catheters before administering the test. This allows for “complete cardiopulmonary hemodynamic and peripheral tissue O2 extraction analyses, without which only the degree of impairment (maximum Vo2) and the identification of a pulmonary mechanical limitation to exercise are possible.
