Gas exchange efficiency slopes to assess exercise tolerance in chronic obstructive pulmonary disease
The OUES may be less useful in advanced COPD with exertional hypoxemia. The [Formula: see text]<sub>E</sub>-[Formula: see text]<sub>CO2</sub> slope, which is independent of [Formula: see text]<sub>E</sub>, focuses on oxygen consumption ability and exercise tolerance in COPD, regardless of the exertional hypoxemia level and COPD grade. Therefore, the [Formula: see text]<sub>E</sub>-[Formula: see text]<sub>CO2</sub> slope might be useful in establishing or evaluating tailor-made therapies for individual patient's pathologies in COPD as an indicator focusing on oxygen consumption ability.
