Indicator Description
Date and Time If you are in Detailed view, the current date and time appear
in the top right corner of the panel. (In Detailed View Off, they
appear in the center panel.)
Patient Breath This symbol displays during a patient-triggered breath.
Airway Pressure
Manometer and
Peak Pressure
Symbol The manometer (bar graph) displays the airway pressure in the
patient circuit at all times. The manometer bar moves to the
right as pressure increases during inhalation, and moves to the
left as pressure decreases during exhalation. The peak pressure
is also indicated on this bar. It is positioned according to the
maximum patient pressure reached during each breath. The Peak
Pressure symbol appears as a blue bar on the manometer. If a
High Inspiratory Pressure alarm occurs, the Peak Pressure symbol
changes from blue to red.
Low Pressure
Indicator
L
If you enable a volume therapy mode, this indicator appears
below the manometer bar, indicating the low pressure alarm
setting.
High Pressure
Indicator
H
If you enable a volume therapy mode, this indicator appears
below the manometer bar, indicating the high pressure alarm
setting.
Pressure This indicator displays the current patient pressure. This only
appears in detailed view.
Respiratory Rate (RR) This indicator displays the measured respiratory rate in Breaths
Per Minute (BPM). This only appears in detailed view.
Exhaled Tidal
Volume (Vte) This indicator displays the estimated exhaled tidal volume in
milliliters and reflects compensation for BTPS. This only appears in
detailed view when Passive Circuit is selected.
Inhaled Tidal
Volume (Vti) This indicator displays delivered tidal volume in milliliters and
reflects compensation for BTPS. This only appears in detailed view
when the Active with PAP Circuit is selected.
