This is a prospective, randomized crossover study for evaluation of the efficacy and safety of long-term nocturnal high-flow nasal cannula therapy (with the myAIRVO2) in stable COPD patients with the global initiative for chronic obstructive lung disease (GOLD) stage 2-4, PaCO2 >=45 torr and hypercapnia who require home oxygen therapy (HOT) using health related quality of life (HRQOL).

Treatment
Device,equipment |
Arm A (1-12 weeks):
The treatment cycle is 6 weeks and is continued for up to 2 cycles (12 weeks). Subjects receive HOT plus nocturnal high-flow nasal cannula therapy with the myAIRVO2 for the 1st cycle, and HOT only for the 2nd cycle.
The myAIRVO2 is used for 4 hours or more per day with flow rates of 40 L/min. HOT is used in the same way as the subject's current treatment at starting the study.
Arm B (1-12 weeks):
The treatment cycle is 6 weeks and is continued for up to 2 cycles (12 weeks). Subjects receive HOT only with the myAIRVO2 for the 1st cycle, and HOT plus nocturnal high-flow nasal cannula therapy for the 2nd cycle.
The myAIRVO2 is used for 4 hours or more per day with flow rates of 40 L/min. HOT is used in the same way as the subject's current treatment at starting the study.
Continuation period (13-52 weeks):
If subjects wish, HOT plus the myAIRVO2 is continued for total up to 52 weeks after the 2nd cycle.

Not applicable |
Male and Female
1. Patients who are diagnosed with the global initiative on obstructive lung disease (GOLD) stage 2-4 COPD.
2. Patients who have received nocturnal HOT 16 hours or more per day for 1 month or more at the time of the informed consent.
3. Patients with PaCO2 <= 60 torr and >= 45 torr at screening.
4. Patients who agree to participate in the study with the written informed consent.
1. Patients with severe kidney, liver or cardiovascular disease.
2. Patients with active malignant tumor.
3. Patients with acute disease.
4. Patients with any history of obstructive sleep apnea syndrome.
5. Patients with diseases affecting the efficacy endpoints who are regarded as inadequate for the study by the investigators.
6. Patients who have experienced a COPD exacerbation within the past 6 weeks prior to the informed consent.
7. Patients who have received nocturnal noninvasive positive pressure ventilation (NPPV), or had received it within 6 weeks prior to the informed consent.
8. Patients with history of tracheotomy, severe pharyngeal surgery or severe nasal cavity surgery within the last 6 months.
9. Patients who are pregnant.
10. Patients with cognitive impairment or mental disorder who are regarded as inadequate to evaluate for the study by the investigators.
11. Patients who are regarded as being unable to operate the myAIRVO2 inadequately at home by the investigators.
12. Patients who have participated in the other study at the time of the informed consent, or will participate in the other study.
13. Any other cases who are regarded as inadequate for the study enrollment by the investigators.
