Timed (T) Mode
In Timed (T) mode, the device delivers bi-level pressure support.
This mode delivers Mandatory breaths only. A Mandatory breath
is delivered according to the prescribed BPM and inspiratory time
settings. This also means that the ventilator will not respond to
patient effort. In this mode, an IPAP is delivered during inhalation and
a lower EPAP is delivered during exhalation. The following illustration
describes these concepts.
