SELECTION OF MODE
When you switch on the machine, it will calibrate itself and display mode selection screen.
You can select the mode of operations by pressing up or low keys. Once it displays the mode
you desire, to select it press next, it will activate that mode.
Machine Mode- In machine control mode it will deliver the set volume at max set pressure with
fixed breaths per minute triggered by machine as per the settings. This mode should be selected
when the patient is not able to breathe on his own.
Assisted Mode- It is pressure control SIMV. In machine control mode it will deliver the set
volume at max set pressure with fixed breaths per minute triggered by machine as per the
settings. This mode should be selected when the patient is not able to breathe on his own.
Weaning Mode- In this mode, machine calculates and displays no of breaths triggered by the
patient as compared to the set rate of breath per minute. It also displays breaths triggered by
machine.
SETTING VOLUME PER BREATH
You can set the volume per breath from 100 to 600ml (in the steps of 50ml). Adjust desired
volume on screen by pressing up or low keys and press next. The volume should be calculated
on the basis of 8 to 10 ml per kg of body weight. For example we can go for 500 ml volume for 12
breath per minute for an average 50 kg weight patient but if the breaths per minute are high then
the volume should be reduced so that it is within the limit of 5 to 8 litres per minute.
So for the 20 breaths per minute rate, the volume should be 250 ml for the same patient.
SETTING MAXIMUM PRESSURE LIMIT
It is the maximum pressure with which you want to ventilate the patient. You can set the
maximum pressure from 6 to 50 cm of H2O in the steps of 2cm of H2O. If the resistance goes
beyond that, and pressure increases it will stop the compressor and oxygen giving high
pressure alarm. It will also display what was the amount of volume delivered as against set
volume. Adjust the desired pressure by pressing up or low keys and press next.
SETTING OF BREATHS PER MINUTE
On this screen you can set the breaths per minute you desire from 5 to 40 breaths per minute.
Adjust the desired value by pressing up and low keys and press next. These are the minimum
breaths machine will trigger if not triggered by the patient.
