It means the character that performed that trial probably has COPD. They can attain air contained by, thus the high sit (98%), but have difficulty exhaling the the atmosphere (low FEV1 and FVC). The 13 and 38 are percents and will be above 80 in majority people. What type of COPD they may enjoy is not clear from the the 3 numbers you gave, but it will be chronic bronchitis, emphysema, asthma, cystic fibrosis, or atelectasis.
the O2 sit rate is the percentage of expected oxygen in your blood. Perfect would be 100 and 98 is VERY virtuous.
FEV is forced expiratory capacity - how much you can breath out, as defiant FVC which is forced volume capacity, or how much nouns you can breathe in when you try really rugged to take a gaping breath. People with emphysema enjoy trouble breathing out so their FEV will be low. People who have lung scarring that prevents them from taking insightful breaths will have a low FVC. Hope that help.
