A breath biofeedback computer game for children with cystic fibrosis.

Author information

  • 1University of Vermont, Burlington, USA.


The authors sought to develop and test a breath-controlled video game using a digital spirometer that, by providing visual breath biofeedback, could promote awareness of breathing techniques in children with cystic fibrosis (CF). To assess improvement in game performance during hospitalizations for CF exacerbations, the authors conducted a trial on 10 inpatients. Subjects had at least five 15-minute exposures to a breath biofeedback game that challenged them to track a moving target using their breath. Subjects reacted positively to the breath tracking challenge. Repeated-measures analysis of variance of a tracking fidelity statistic showed improvement in eye-breath coordination over 5 sessions ( P = .026). It was concluded that an electronic breath game is safe and can improve breath awareness among children with CF. This technology could also contribute to awareness of respiratory symptoms and foster social ties among CF patients.
