1. Heart Rate Variability in Patients with Chronic Obstructive Lung Disease and Nocturnal Oxygen Desaturation / Análise da Variabilidade da Freqüência Cardíaca em Pacientes Portadores de Doença Pulmonar Obstrutiva Crônica e Dessaturação Noturna
Background: The autonomic nervous system may be disturbed in chronic respiratory failure. Chronic hypoxemia may result in sympathetic activation. There are few studies showing the role of the autonomic nervous system in patients with chronic obstructive lung disease (COPD) and nocturnal oxygen desaturation. Objective: To analyze the sympathetic and parasympa

2. Changes in nocturnal oximetry after treatment of exacerbations in cystic fibrosis.
Sleep related arterial oxygen desaturation has been described in clinically stable young adults with cystic fibrosis. The incidence and severity of nocturnal oxygen desaturation in children during infective exacerbations and the changes that occur with treatment were examined. Forty five children with proved cystic fibrosis, median age 8.9 years, admitted to

3. Non-apnoeic REM sleep induced nocturnal oxygen desaturation treated by nasal continuous positive airway pressure.
Non-apnoeic oxygen desaturation related to rapid eye movement (REM) sleep in a patient with hypothyroidism, obesity, respiratory failure, and cardiac failure was improved by treatment with nasal continuous positive airway pressure of 10 cm H2O.

4. Nocturnal oxygen desaturation and spirometric parameters in adults with cystic fibrosis.
BACKGROUND--Correction of nocturnal hypoxaemia in patients with cystic fibrosis may delay the development of pulmonary hypertension. Descriptive statistics used for nocturnal arterial oxygen saturation (SpO2) lack uniformity. The relationship between SpO2 and spirometric parameters has not previously been explored in a large number of exacerbations in adult

5. Prediction of oxygenation during sleep in patients with chronic obstructive lung disease.
The accuracy of a prediction equation for assessing the lowest arterial oxygen saturation (SaO2) during sleep was determined in 24 consecutive patients with chronic obstructive lung disease referred for assessment for home oxygen therapy. Subjects had a mean (SD) FEV1 of 0.81 (0.31) litre and an FEV1/FVC of 37% (12%). There was reasonable agreement between p

6. Oxygen treatment of sleep hypoxaemia in Duchenne muscular dystrophy.
Patients with Duchenne muscular dystrophy develop progressive ventilatory muscle weakness and often die of respiratory complications. Recurrent, often profound, hypoxaemia has been shown in a previous study by this group to occur during rapid eye movement (REM) sleep in these patients before they develop sleep symptoms. In this study the efficacy and physiol

7. Ventilation and gas exchange during sleep in patients with interstitial lung disease.
Ventilation and gas exchange during overnight sleep was studied in a group of seven patients with severe interstitial lung disease (mean vital capacity 50%, mean diffusing capacity 46% predicted), to see whether clinically significant oxygen desaturation occurred. Patients with a history of loud snoring or clinically significant airflow obstruction were excl

8. Effects of captopril and oxygen on sleep apnoea in patients with mild to moderate congestive cardiac failure.
OBJECTIVES--To determine the effects of captopril and oxygen on sleep quality in patients with mild to moderate cardiac failure. DESIGN--An open observational study. PATIENTS--12 patients with New York Heart Association class II-III heart failure were studied at baseline. 9 of these patients were then examined at the end of 1 month of treatment with captopri

9. Flow-volume curves and sleep-disordered breathing: therapeutic implications.
To assess the relationship of abnormal flow-volume curves during awake periods to the clinical severity of sleep-disordered breathing and the need for surgical treatment of obstructive sleep apnoea, flow-volume curves were measured in 72 adults with obstructive apnoea. Patients in whom surgery was recommended for standard clinical indications had significant

10. Nocturnal hypoxaemia and quality of sleep in patients with chronic obstructive lung disease.
Fifty patients with chronic obstructive lung disease were questioned about their sleep quality and their responses were compared with those of 40 similarly aged patients without symptomatic lung disease. Patients with chronic obstructive lung disease reported more difficulty in getting to sleep and staying asleep and more daytime sleepiness than the control

11. Induction of sleep apnoea with negative pressure ventilation in patients with chronic obstructive lung disease.
BACKGROUND: Negative pressure ventilation provides intermittent non-invasive ventilatory assistance for patients with advanced chronic obstructive lung disease. Upper airway obstruction during sleep, a reported complication of the technique, may, however, limit its clinical applicability. METHODS: The effects of nocturnal negative pressure ventilation on ven

12. Changes in day and night time oxygenation with protriptyline in patients with chronic obstructive lung disease.
The effect of protriptyline, a tricyclic antidepressant, on sleep architecture, nocturnal arterial oxygen desaturation, pulmonary function, and diurnal arterial blood gases was investigated in an open study of 14 patients with stable chronic obstructive lung disease. Daytime and overnight measurements were made before and 2 and 10 weeks after they started pr
