| Outline of Final Research Achievements |
We examined the factors contributing to sleep disturbance in patients with chronic lung disease (CLD). CLD patients showed sleep disturbance such as longer sleeping latent time, a lot of interrupted sleep, lack of deep sleep, and deteriorated good sleep, and 38.1% of CLD showed moderate-to-severe sleep disordered breathing (SDB). Sympathetic nerve activity (SNA) and parasympathetic nerve activity (PNA) evaluated by pulse rate variability showed no significant difference, but the stability of PNA was deteriorated in CLD patients, especially, in the patients with nocturnal oxygen desaturation, and the instability of PNA significantly correlated with hypoxemia at night. On the other hand, the CLD patients prescribed long-term oxygen therapy and maintained their SpO2>90% at night showed significant improvement in the instability of PNA. These findings suggest that the presence of SDB and nocturnal hypoxemia due to hypoventilation may deteriorate the sleep quality in CLD patients.
