How Pseudomonas aeruginosa Affects People With Cystic Fibrosis

What is Pseudomonas aeruginosa?

What is Pa?

Pa is a harmful bacteria found in the lungs of almost half of all people with cystic fibrosis (CF).1 People that suffer from chronic Pa infections tend to experience persistent, worsening symptoms such as coughing, wheezing, and mucus production.3,4 These worsening symptoms make it harder to breathe.3,4 Once Pa settles in the lungs and becomes chronic, the person with CF's lung function may decline (eg, FEV1*).5

Having Pa infection becomes more common as people with CF age

As people with cystic fibrosis get older, they are more likely to have Pa infection in their lungs.6 For example, about 30% of children with CF have a Pa infection by age 10, but that number climbs to 60% by age 24 and to over 70% by adulthood. Over time, Pa infection may cause irritation and damage to the lungs that won't go away.2 Therefore, it's important to treat Pa sooner rather than later.

FEV1 (Forced Expiratory Volume) measures the amount of air that can be forcefully blown out in 1 second after taking a deep breath.7
