Incidence of nocturnal desaturation while breathing oxygen in COPD patients undergoing long-term oxygen therapy.
STUDY OBJECTIVE It is suggested that oxygen flow be increased by 1 L/min during sleep in COPD patients undergoing long-term oxygen therapy (LTOT) in order to avoid nocturnal desaturations. The purpose of this study was to investigate the occurrence of nocturnal desaturations while breathing oxygen in COPD patients receiving LTOT. SETTING Inpatient/university hospital. PATIENTS We studied 82...
متن کاملPredictive indexes of nocturnal desaturation in COPD patients not treated with long term oxygen therapy.
Nocturnal oxygen desaturation during the sleep is very frequent in patients affected by chronic obstructive pulmonary disease (COPD). Hypoventilation, rather than sleeping apnea, is commonly considered as the most relevant factor in the onset of nocturnal oxygen desaturation. On this topic, the Authors have carried on a study on the nocturnal hypoxemia in 70 hospitalized COPD patients with a me...
متن کاملNocturnal oxyhemoglobin desaturation in COPD patients with arterial oxygen tensions above 60 mm Hg.
We studied 152 COPD patients with a daytime PaO2 greater than or equal to 60 mm Hg using formal polysomnography (EEG, airflow, respiratory muscle movement, ear oximeter) to detect the presence of nocturnal, nonapneic, oxyhemoglobin desaturation. Nine subjects were disqualified by the unexpected discovery of sleep apnea, as were another eight because they could not sleep in the laboratory settin...
متن کاملPredictors of oxygen desaturation during submaximal exercise in 8,000 patients.
STUDY OBJECTIVES To determine predictors of oxygen desaturation during submaximal exercise in patients with various lung diseases. DESIGN AND SETTING This retrospective case series used pulmonary function laboratory results from all patients referred to a major tertiary-care center. PATIENTS AND MEASUREMENTS All patients > or = 35 years old who underwent spirometry, diffusing capacity of th...
متن کاملPredictors of oxygen desaturation in patients undergoing diagnostic bronchoscopy.
BACKGROUND Oxygen desaturation is not uncommon during bronchoscopy. We sought to identify factors predictive of desaturation during flexible bronchoscopy. METHODS Over eight months, we enrolled 137 randomly selected patients who were undergoing fiberoptic bronchoscopy at our medical center. The patients' oxygen saturation was monitored on their arrival and during the procedure by finger pulse...
