S mode

Main features

•

Pressure supported

•

Patient triggered

•

Flow controlled

•

Device only responds to spontaneous breathing

•

Apnoea sound

The transition from the EPAP

to the IPAP

is triggered by the patient’s spontaneous breath-

ing alone. The pressure is decreased to the EPAP when the inspiration flow ends. In addi-
tion, a safety frequency can be activated. This ensures patients are still ventilated with
the set parameters (frequency, I:E) in case of respiratory arrest.
