Effect of nasal positive expiratory pressure (PEP) on 6-min walk test (6MWT) distance and pre- to post-exercise increase in lung volumes in each individual subject (n = 20). Effect of nasal positive expiratory pressure (PEP) on 6-min walk test (6MWT) distance and pre- to post-exercise increase in lung volumes in each individual subject (n = 20). A: Total lung capacity (difference between means −0.63 ± 0.80 L, P = .002). B: Residual volume (difference between means −0.56 ± 0.75 L, P = .004). C: Functional residual capacity (difference between means −0.48 ± 0.86 L, P = .021). D: 6MWT distance (difference between means −30.8 ± 30.0 m, P = .001). PEP = positive expiratory pressure.
