There was an excellent correlation between on- and off-line values. Bland and Altman plots showed good agreement between on- and off-line FEno. Seventy-four out of 79 children were able to perform a correct off-line procedure. Geometric mean±sem FEno in healthy children was 4.9±1.2 parts per billion (ppb) for male children and 7.6±1.1 ppb for female children. It can be concluded that off-line fraction of exhaled nitric oxide measurements with dynamic flow restriction are feasible in young children and correspond to on-line values. M.W.H.
