Fig. 6.5: Alarm control panel
The Yes and No buttons are used for confirming the ventilator’s messages and actions.
The Info button allows for displaying the previous parameters and other information. The up
and down arrow buttons allow for increasing and decreasing the parameter that is being set
up. The last button suppresses the sound alarm for 2 minutes. The potentiometers allow for
setting up maximum allowed breathing frequency and maximum allowed pressure in the
airways. The alarm sets off after exceeding the set up values. The apparatus also allows for
setting up minimum and maximum minute ventilation and minimum and maximum permitted
oxygen concentration. The alarms are activated in case there is a deviation of the actual
minute ventilation or oxygen concentration value outside the set-up interval.
Patient monitor
The panel (Fig. 6.6) can be found in the left upper part of the ventilator’s front panel.
It shows the actual state of the patient’s ventilation. It is important to say that this panel
operates independently from the ventilator. There are three indicators on the panel, and three
values may be displayed at the same time, selected by pushing the appropriate buttons under
each of the indicators. Altogether, it is possible to gather information about 14 parameters.
