[VO2 max: technique and practical importance].
NORMAL SITUATION: Ergonometric spirometric measurement of O2 consumption and CO2 production (VO2max) can be used to assess adaptation of the oxygen transportation system to exercise. In the normal situation, the capacity to sustain exertion in everyday physical activities depends directly on the capacity of this system to adapt, i.e. the level of physical training. PATHOLOGICAL CONDITIONS: In diseased patients, this test can measure the degree of non-adaptation and the efficacy of compensatory mechanism of the oxygen transport system. It can be used as a pathophysiological diagnostic tool for following divers disease states, particularly heart conditions. Spirometry is a key test used in all cardiology centers to assess the degree of heart failure.
