👉 Cystic Fibrosis Ventilation Syndrome is a genetic disorder characterized by persistent cough, breathlessness, and frequent wheezing in children with cystic fibrosis. It occurs due to an abnormal immune response against the body's own cells and tissues that can lead to inflammation and damage. This condition often affects the lungs and airways, leading to chronic obstructive pulmonary disease (COPD). The term "CBPV" refers specifically to this respiratory disorder.
