*'''BiSoft0''' (Off) is useful if you have good exhalation shape but for late collapse of inspiration. This mode will delay the arrival of maximum pressure support arriving later in inspirationand help fill out the second half of the inhalation.

*'''BiSoft1''' & '''BiSoft2''' will begin deliver some extra support during late in exhalation, but direct a good large amount of pressure support at early to mid inspiration.
