How can I handle COPD discharge instructions, meds, and oxygen at home?

[JosephH]

My father was recently hospitalized for a severe COPD exacerbation, and now that he's home, I'm his primary caregiver trying to help him manage his Chronic Obstructive Pulmonary Disease, but I feel completely out of my depth with his medication schedule, oxygen therapy, and recognizing early warning signs of another flare-up. His pulmonologist provided discharge instructions, but they're complex and my father gets frustrated and short of breath when we try to go over them, making it hard to ensure he's using his inhalers correctly. For other caregivers or patients, what practical tools or strategies have you found most effective for daily management and communication with your healthcare team? How do you balance encouraging activity to maintain strength with the very real fear of triggering breathlessness, and what resources are available to help families like ours navigate this progressive disease?
