The set target airway pressure value is displayed in the adjacent
window if the FLIGHT 50 Ventilator is ventilating.
A “
PRESS AGAIN
” message appears in the Message Display Window.
2. Adjust the set target airway pressure by pressing the
▲Up/▼Down
controls while the LED and numerical display are blinking.
3. If the FLIGHT 50 Ventilator is ventilating, you will need to press the

O/mbar
The Ptrig setting determines trigger sensitivity in terms of how far airway
pressure must drop below the set baseline pressure for a patient’s
spontaneous efforts to be detected. The Ptrig LED indicator illuminates each
time the airway pressure reaches the set Ptrig level, and turns off once the
airway pressure has returned to baseline pressure. The blinking Ptrig LED is
referred to as the Patient Effort Indicator. The Ptrig value is displayed in the
adjacent window.
Set Ptrig as close to 0.0 cmH

O as possible without auto triggering to
maximize triggering synchrony.
