What does a person who has emphysema feel?

A person like this feels like they can't get any air out only in.

A person with emphysema externally presents with a barrel shaped chest. This is due to reduction in the elasticity of lungs. Also, the patient feels shortness of breath, fatigue and gets tired quickly.

If emphysema has lots of phlegm or fluid in the lungs, the person can feel like they are drowning. Even without phlegm or fluid, taking a breath can feel like an elephant is sitting on the chest.
