CRESPO, Tatiana et al. Chronic obstructive pulmonary disease and pulsioximetry during night sleep. Rev Cub Med Mil [online]. 2005, vol.34, n.4, pp. 0-0. ISSN 1561-3046.

An observational descriptive study of the monitoring of the saturation or arterial oxygen during sleep was conducted in 21 male patients with an average age of 53.4 years old that presented a chronic obstructive pulmonary disease (COPD). All of them had normoxemia or mild day hypoxemia and different degrees of obstructive ventilatory dysfunction. These results were attained by the studies of pulmonary function (spirometries) and of the gases in arterial blood (gasometries), in addition to night continuous 3-hour pulsioximetry (180 min) by using the OXY9800 equipment made in Cuba in recording mode. A significant night desaturation was considered when the patient maintained himself during 30 % or more of the recording time with a saturation of 90 % (TSaO 2 < 90 % ³ 30 %). According to this criterion, patients were classified into 2 groups: desaturants and non-desaturants . Of the 21 patients, 6 were desaturants, accounting for 28.6 %. The analysis of the results of logistic regression in our study identified the FEV1 in its real and percentage value, as a predictor of the night desaturation of oxygen in patients with COPD.
