Chapter 1: Introduction 19
ST Combination of spontaneous breathing and controlled breathing (timed) - if
the patient is capable of breathing on their own, the device works in S mode.
If the patient is no longer able to breathe spontaneously, the device automati-
cally enters T mode and ventilates the patient with the set frequency. The mode
is switched to T mode after a set delay time lapses.
T Ventilation (timed) – with fixed inspiration time. If the trigger function is dis-
abled, the patient is ventilated with the set parameters.
If the trigger is enabled,
the device accepts spontaneous patient inspiratory efforts. The patient is then
able to increase the breathing rate through his own efforts.
