Sensor Inspection
-
The value for the opening of the chosen valve may be increased or decreased with selection keys
This opening value may range between 0 (Closed Valve) and a maximum of 4095 (Valve completely
opened).
If press “ctrl” +“selection” the values go up or dawn in tens.
-
All valves (Opening value = 0) may be closed with the “Reset” key.
The
“AirVal” line corresponds to the air proportional valve.
The
“OxyVal” line corresponds to the oxygen proportional valve.
The
“SuffVal” line corresponds to the antisofocation valve
The
“PeepVal” line corresponds to the PEEP proportional valve.
Air and Oxygen Valves (AirVal and OxyValv)
When the opening value is increased with a value ranging between 0 and 4095, we will notice that the
valve remains closed while the opening value is lower than 900 units (approximately). When the
opening exceeds this value, the valve begins to be opened progressively (air begins to flow through the
inspiratory outlet
) until the maximum value is reached (greater than 16
0 L/min), i.e., when the opening
value reaches 4095 units.
The valve can then be closed using the
“Reset”.
Sensors Check
In the upper left corner of the window, there is an 8
-line column.
Each lines
shows the digitalized readings of the flow and pressure
. These readings will vary depending
on the flows or pressures being applied on the sensors.
When there are no supply gases connected to the device, the readings given by these sensors are
the ones
shown in the following table:
The second column
shows a value equal to the first one
but multiplied by four (do not take this into account).
