Cerebral desaturation during exercise reversed by O2 supplementation.
The combined effects of hyperventilation and arterial desaturation on cerebral oxygenation ([Formula: see text]) were determined using near-infrared spectroscopy. Eleven competitive oarsmen were evaluated during a 6-min maximal ergometer row. The study was randomized in a double-blind fashion with an inspired O2 fraction of 0.21 or 0.30 in a crossover design. During exercise with an inspired O2...
متن کاملEffect of exercise-induced arterial O2 desaturation on VO2max in women.
PURPOSE We have recently reported that many healthy habitually active women experience exercise induced arterial hypoxemia (EIAH). We questioned whether EIAH affected VO2max in this population and whether the effect was similar to that reported in men. METHODS Twenty-five healthy young women with widely varying fitness levels (VO2max, 56.7 +/- 1.5 mL x kg(-1) x min(-1); range: 41-70 mL x kg(-...
متن کاملLong-term oxygen therapy: in a perfect world.
This issue of RESPIRATORY CARE contains 2 papers of interest that deal with long-term oxygen therapy (LTOT). In the first, Martí et al investigated the efficacy of 2 oxygen-conserving devices in correcting exercise-induced hypoxemia in subjects with either COPD or interstitial lung disease (ILD). Of the 59 subjects who completed the study, 28 were diagnosed with COPD and 31 were diagnosed with ...
متن کاملKinetics of changes in oxyhemoglobin saturation during walking and cycling tests in COPD.
BACKGROUND The patterns and kinetics of changes in SpO2 in the 6-min walk test (6MWT) and cycling test have not been addressed in patients with COPD. METHODS We studied 60 COPD subjects, with a mean ± SD FEV1 of 54 ± 18% of predicted. We compared the changes in SpO2 (ΔSpO2) within and between the 2 tests, and the differences between the desaturators and non-desaturators. RESULTS In the 6MWT...
متن کاملUsefulness of the 6-minute walk test as a screening test for pulmonary arterial enlargement in COPD
PURPOSE Pulmonary hypertension and exercise-induced oxygen desaturation (EID) influence acute exacerbation of COPD. Computed tomography (CT)-detected pulmonary artery (PA) enlargement is independently associated with acute COPD exacerbations. Associations between PA to aorta (PA:A) ratio and EID in patients with COPD have not been reported. We hypothesized that the PA:A ratio correlated with EI...
