Ventilation parameters such as set therapy mode,
therapy pressures (CPAP pressure only in CPAP mode)
in hPa, the selected patient circuit and current
respiratory frequency in 1/min are shown in the
display.
Note:
1.01973 hPa correspond to 1 cm H
2
O.
The bar chart shows the pressure curve for inspiration
and exhalation.
The respiratory phase change display shows whether the
current respiratory phase was triggered spontaneously
by the patient (
S
) or by the machine (
T
). Depending on
respiratory phase, the display switches from left
(inspiration) to right (exhalation).
See the section entitled “ Symbols used in the display”
