Exercise-induced oxygen desaturation in chronic obstructive pulmonary disease patients.
Interest in the causes and characteristics of chronic obstructive pulmonary disease (COPD) and its clinical manifestations has grown in the last 10 years. The range of clinical symptoms and other specific characteristics of COPD patients has led it be considered more as a syndrome than a disease, and many investigators have been motivated to define new phenotypes that reflect the particular fea...
متن کاملPrevalence and prediction of exercise-induced oxygen desaturation in patients with chronic obstructive pulmonary disease.
BACKGROUND Previous studies with small sample sizes reported contradicting findings as to whether pulmonary function tests can predict exercise-induced oxygen desaturation (EID). OBJECTIVE To evaluate whether forced expiratory volume in one second (FEV(1)), resting oxygen saturation (SpO(2)) and diffusion capacity for carbon monoxide (DLCO) are predictors of EID in chronic obstructive pulmona...
متن کاملHyperoxic interval training in chronic obstructive pulmonary disease patients with oxygen desaturation at peak exercise.
High-intensity work might not be preserved in chronic obstructive pulmonary disease (COPD) during whole-body exercise due to ventilatory limitations that exceed metabolic limitations, resulting in reduced training adaptations. The purpose of the present study was to address the hyperoxic effect during training and testing in COPD patients with hypoxemia at peak exercise. Six COPD and eight coro...
متن کاملRelationships between exercise-induced pulmonary hypertension and nocturnal desaturation.
This important observation prompted us to report here the results of a prospective study that we conducted during the 1990s, which has only been published in abstract form [2]. Nine male COPD patients with mild hypoxaemia at rest (six current and three ex-smokers) were included in the study (age: 66.9¡5.8 yrs, forced expiratory volume in one second/ forced vital capacity: 43.2¡15.5% predicted, ...
متن کاملNocturnal desaturation and serum erythropoietin: a study in patients with chronic obstructive pulmonary disease and in normal subjects.
1. To clarify the relationship between nocturnal oxygen desaturation and erythropoietin production in patients with chronic obstructive pulmonary disease, we determined arterial oxygen saturation and serum immunoreactive erythropoietin levels over 24 h in eight patients with chronic obstructive pulmonary disease and in nine normal subjects. 2. In the normal subjects, there was a significant cir...
