[The evaluation of the severity of nocturnal oxygen desaturation of patients with obstructive sleep apnea hypopnea syndrome].
Oxygen desaturation is common among patients with sleep apnea. This study was designed to evaluate the methods used to express the severity of oxygen desaturation in patients with obstructive sleep apnea hypopnea syndrome. ⋯ The best method of expressing the severity of oxygen desaturation in patients with obstructive sleep apnea hypopnea syndrome needs the combination of several conventional indices of oxygen desaturation (lowest oxygen saturation, oxygen desaturation index, and the percent of the total time with oxygen saturation level lower than 90%).
