Abstract This chapter describes how the most important parameter measured during a cardiopulmonary exercise test (CPET) is the volume of oxygen taken up by the body at peak exercise. This is called the maximum oxygen uptake, or VO2max. Sometimes the terms ‘peak’ and ‘maximal’ are also used to describe oxygen uptake.

Abstract Muscular exercise requires transitions to and from metabolic rates often exceeding an order of magnitude above resting and places prodigious demands on the oxidative machinery and O 2 ‐transport pathway.

New England Journal of Medicine, 1971
KNOWLEDGE of how oxygen is transported from the ambient air to the tissue cells of the body is essential to an understanding of the mechanisms by which the body adapts to the oxygen demands of muscular exercise. The requirement of oxygen by the various tissue cells of the body is met by the combined cardiovascular and pulmonary systems, which function ...

Oxygen uptake profile of the human cornea [PDF]
Australasian journal of optometry, The, 1986 A polarographic oxygen sensor was used to measure corneal oxygen uptake (COU) centrally and 4mm proximally at nasal, temporal, superior, and inferior locations on 10 human subjects.

Abstract Key Points: • Maximum oxygen uptake (VO2max) is a key CPET parameter. • A peak exercise VO2 or VO2max of <80% of predicted is abnormal. • A low VO2max is associated with a poor outcome in many conditions.

Blood rheology and oxygen uptake
Clinical Hemorheology and Microcirculation, 1990Continuously measured oxygen uptake during constant work exercise (15′ SOW) reveals increasing oxygen consumption in individuals with elevated blood viscosity parameters, indicating persistent contribution of anaerobic glycolysis during steady state exercise far below expected “anaerobic threshold”.

Oxygen Uptake and Surfactant Replacement
1988Increased capillary permeability, associated with damage to the alveolar epithelium, can lead to derangement of pulmonary surfactant through a variety of mechanisms. These include: washout of alveolar phospholipids into the interstitial tissue and blood stream; inactivation by plasma components; surfactant depletion by foaming or ventilation with large

Kinetics of oxygen uptake at the onset of exercise near or above peak oxygen uptake
Journal of Applied Physiology, 2000We tested the hypothesis that kinetics of O2 uptake (V˙o 2) measured in the transition to exercise near or above peakV˙o 2(V˙o 2 peak) would be slower than those for subventilatory threshold exercise. Eight healthy young men exercised at ∼57, ∼96, and ∼125%V˙o 2 peak.

Oxygen uptake of the human fetus at term
Acta Obstetricia et Gynecologica Scandinavica, 2009AbstractObjective. To measure oxygen uptake of term human fetuses and compare the values between those delivered vaginally following normal labor and those delivered by cesarean section before the onset of labor. Design. This was a prospective cross‐sectional study. Setting. University teaching hospital. Sample.
