Table 3 Comparison of the standard method and proposed method in unchanged body positions

From: Reducing the airflow waveform distortions from breathing style and body position with improved calibration of respiratory effort belts

Body position Compared methods ΔR2 Δ(relative RMSE)
Sitting SM→PM(N=8) 18.9 ± 7.7 -43.8 ± 9.1
SM→PM(N=16) 20.6 ± 7.2 -50.0 ± 6.6
PM(N=8)→PM(N=16) 1.4 ± 1.1 -10.4 ± 5.8
Supine SM→PM(N=8) 19.1 ± 10.5 -45.3 ± 10.7
SM→PM(N=16) 20.3 ± 10.6 -49.6 ± 11.8
PM(N=8)→PM(N=16) 0.9 ± 0.5 -8.4 ± 5.3
  1. The relative improvement of R2 and relative RMSE (average value ± SD, in [%]) between predicted airflows with the standard method and proposed method with N values of 8 and 16. The notation ´a→b´ denotes a performance improvement when changing from method ´a´ to method ´b´.
