Sleep induced hypoxemia in chronic obstructive pulmonary disease.
Chronic obstructive pulmonary disease is a leading cause of morbidity and mortality worldwide. Sleep-induced hypoxemia is defined as "an SpO2 (oxyhemoglobin saturation) during sleep of < 90% for more than five minutes with a nadir of at least 85%" or "> 30% of total sleep time with an SpO2 of < 90%" in subject with a baseline awake SpO2 of ≥ 90%. Patients with moderate or severe COPD run a high...
متن کامل[Cardio-Pulmonary-Renal interactions].
Over the past decade, understanding about feedback mechanisms involving the heart, lung and kidney is significantly improved. Each organ injury may trigger hemodynamic, neuro-hormonal and cellular pathway that may damage diverse organs. Recurrent acute on chronic injury may lead to the advanced stage of disease. On the other hand, chronic pathological conditions may decrease functional reserve ...
متن کاملA Study of Cardio Pulmonary Changes during Upper Gastrointestinal Endoscopy
Upper gastrointestinal endoscopy is a commonly performed diagnostic and therapeutic procedure and has many adverse effects like cardiopulmonary complications, complications related to sedation, infectious complications, bleeding and perforation. So this study was undertaken to evaluate important variables like patient’s age, gender and stage of the procedure in relation to the cardiopulmonary c...
متن کاملExercise-induced arterial hypoxemia.
Exercise-induced arterial hypoxemia (EIAH) at or near sea level is now recognized to occur in a significant number of fit, healthy subjects of both genders and of varying ages. Our review aims to define EIAH and to critically analyze what we currently understand, and do not understand, about its underlying mechanisms and its consequences to exercise performance. Based on the effects on maximal ...
متن کاملCardiac function and pulmonary hemodynamics during exercise in COPD
Background COPD is often associated with changes of the structure and the function of the heart. Although functional abnormalities of the right ventricle have been well described in COPD patients with severe hypoxemia, little is known about these changes in patients with normal to mild hypoxemia. Study objectives To assess the structural and functional cardiac changes in COPD patients with norm...
