Variance of time triggered mandatory, patient triggered and reverse triggered breaths. Coefficient of variation for the breath interval and phase angles for ventilator breaths (TOTMECH), patient breaths (TOTNEU) and reverse triggered breaths (TOTNEU). Two bars are displaying the differences between entrained and non-entrained breaths. Coefficient of variation < 15% is considered entrainment. The highest coefficient of variation is seen in non-entrained reverse triggered breaths (91%)
