To select graph rotate the encoder, to select the desired graph push the encoder, to cancel
press the "Menu" button.
Enable/disable filling of graphs
The function allows to select the view of the output curves in the form of outlines or filled
graphs. Filled graphs have better contrast. Inspiratory phase of the respiratory cycle is hig-
hlighted with blue for the hardware and white for spontaneous breaths. In addition the start of
spontaneous inspiration is shown with crimson vertical bar.
To activate the function set "Filled graphs" in the "On" position in the submenu "Graphs".
Displaying of graphs
The scale of pressure graph is selected by user of the Pmax value and in maximum case may
be -20…120 cmH
2
O.
The scale of the rest of the graphs is selected automatically - once for the entire period of the
sweep (at the moment of the transition of the graph through the right border), if the scale
change criterion works.
Pressure graph Paw shows:
•
Marker of the maximum inspiratory pressure Pmax (blue line).
•
PEEP marker (if PEEP > 0 cm
Н
2
О
) (light blue line).
•
Pressure curve (green or blue line, depending on the inspiration/expiratory phase).

Scale of flow rate graph is automatically selected in the range ±250 lpm, depending on the
maximum flow rate in the current mode.
All graphics display instant, current values of parameters in real time and are synchronized on
the common time base.
Displaying of spirometry loops
Spirometry loops are displayed in the mode of 1 and 4 graphs.
At selection of spirometric loop and displaying of 1 graph, two interactive buttons TYPE and
REF are displayed. At the activation of TYPE button, menu of selection of spirometric curve
type appears on the screen:
•
volume/flow V-F,
•
volume/pressure V-P,
•
flow/pressure F-P,
•
vol/pressure V-Paux (option).
Press the appropriate line to select the desired loop type. Press the TYPE button again to hide
the selection of spirometry loop type.
Simultaneously with the current spirometric curve, previous or reference loop is displayed on
the screen in gray.
Setting of the support (reference) loop is performed by pressing the REF button. At pressing
