4.4.4 Initial alarm settings
Alarm thresholds MV for the new patient are set automatically at the start of ventilation: MV max
= 1.5 MV, MV min = 0.7 MV.
Default value of the bottom alarm threshold Vt min = 4.4 ml/kg IBW for all modes. Default value
of the top alarm threshold Vt max - 16 ml/kg of IBW.
During operation at regulation of parameters, limits of alarms do not change. If %MV changes,
the bottom threshold 0.7 MV from 100%MV always remains constant, also as well as the top
threshold of 1.5 MV at setting of %MV in the range from 25 to 100 %. At the setting %MV more
than 100 %, the top alarm threshold is increasing on the corresponding value. For example, if
%MV is set to 200 %, the top alarm threshold is set to 250 %, if %MV is set to 220 % - the alarm
threshold is set to 270 %. If adaptation is enabled, the top alarm threshold is set to 250%MV.
4.4.5 Calibration procedure before the beginning of operation
In some cases before the beginning of operation it is necessary to carry out the calibration.
