Qualidade de Sono e Parâmetros de Dessaturação Nocturna em Doentes com Doença Pulmonar Obstrutiva Crónica e Hipoxémia entre 55-70mmHg (original) (raw)

Revista Portuguesa de Pneumologia, 2001

Abstract

ABSTRACT Nocturnal desaturation is well recnognized in patients with chronic respiratory failure (CRF). Alveolar hypoventilation, particulary in REM sleep, is frequently assumed as the main physiopathological mechanism. This ocurrence is important in patients with mild basal hypoxemia (PaO2 55-70 mmHg) because of the particular position of the PaO2 in the oxyhemoglobin desaturation curve. However, disturbances of the quality of sleep that alter the normal structure of sleep in patients with chronic obstructive pulmonary disease (COPD) has been described in the literature.
