(a) NR,95 is independent of NS; (b) NR,95 is independent of P0; and (c) linear relationship between NR,95 and NB. (d) NR,95 is not significantly affected by the irregularity of respiratory. Specifically, in (a)–(c), 29 patients’ breathing profiles were used to statistically analyze the relationship between the parameters. However, in Fig. (d), 2500 simulated respiratory profiles with different BP and BV have been generated to test the relationship between breathing irregularity and NR,95.
