In this study, we examined whether the severity of apnea–hypopnea during sleep correlated with the daytime hypoxemia and whether daytime hypoxemia improved with long-term nasal continuous positive airway pressure (nCPAP) therapy. PaO2 significantly decreased from 89.8 ± 9.4 Torr (in the control group) to 78.2 ± 5.1 Torr (in the apnea-hypopnea index [AHI] > 90) with an increase in the AHI. Despite the aggravation of apnea–hypopnea 1 year after the nCPAP therapy, the daytime hypoxemia improved. In addition, it appears that daytime hypoxemia improves with long-term nCPAP therapy.
