A comparison of four algorithms for the measurement of interrupter respiratory resistance in adults
Summary The aim of our study was to compare four algorithms for the measurement of respiratory resistance in adults using the interrupter technique. Four methods to estimate alveolar pressure from the mouth pressure during occlusion were assessed in 122 normal adults (57 males, 65 females, aged 18–7...

| description | Summary The aim of our study was to compare four algorithms for the measurement of respiratory resistance in adults using the interrupter technique. Four methods to estimate alveolar pressure from the mouth pressure during occlusion were assessed in 122 normal adults (57 males, 65 females, aged 18–79 yr, mean 41.2 ± 15.6): taking the mean oscillation pressure ( Rint ), performing a linear back extrapolation ( RintL ) or a linear regression for the whole curve ( RintRL ), taking the end-occlusion pressure ( RintE ). Mean values for Rint , RintL and RintRL in males were respectively 0.23 ± 0.04, 0.22 ± 0.04 and 0.22 ± 0.04 kPa s L−1 , not statistically different. In females values were respectively 0.27 ± 0.05, 0.26 ± 0.05 and 0.26 ± 0.05 kPa s L−1 , not statistically different. RintE was higher than the remainder and was the only measure correlating weakly with morphometric variables: RintE = 1.152 − (0.00152 × age (yr)) − (0.00382 × height (cm)), r = 0.31 ( p |
