Emphysema is a lung disease with damaged alveoli. Alveoli is the air sac, the inner walls of the air sacs weaken and rupture, when you exhale, the air sacs can't work properly, then you feel out of breath.

Most people with emphysema also have chronic bronchitis. The two add up to COPD.

Emphysema has 4 stages:

FEV 1 Staging for Emphysema

Stage I = mild: Greater than or equal to 80 percent predicted

Stage II = moderate: Less than 80 percent, greater than 50 percent predicted

Stage III = severe: Less than 50 percent, greater than 30 percent predicted

Stage IV = very severe: Less than 30 percent predicted, or less than 50 percent in chronic respiratory failure

Stage 3 and 4 are the advaned stage.

    Is it same as COPD?
    Emphysema is a type of COPD. COPD is an umbrealla term, emphysema, chronic bronchitis, are both COPD.

    In stage 4, all the symptoms will worsen. Daily tasks become so hard, patients can show blue lips and nails because of low oxygen level. Oxygen therapy will be helpful.

    Emphysema is later stage of COPD. The stage is typically based on the FEV1 expressed as a percentage of the predicted "normal" for the person's age, gender, height, and weight. The FEV1 is a index in lung function test. You may feel  short breath when you have sligh physical exercise.  Long time oxygen treatment(LTOT) maybe helpful.
