Hi there, thanks for asking. As you mentioned your husband has breathing problem at night. It is common in COPD
patients and as you are using, he may use the CPAP machine. There are also some other ways to help to this problem. Weight loss
can help. He should lose 20 kg to help him. Medications for COPD can help a lot for him. There are also some other ways like medications that help him stay awake during the day. You can ask his doctor about more. Best wishes.
