4.7 Setting of ventilation modes and parameters
4-17
Parameter setting in the apnea mode:
•
At the apnea ventilation mode with volume control respiratory rate (RB) and tidal volume
(Vapnea) are set automatically but can be corrected by the user.
•
At the apnea ventilation mode with pressure control respiratory rate (RB) is set automatically
by the same rules depending on the patient’s weight. The target inspiratory pressure in the
apnea ventilation mode with pressure control (Piapnea) is set by user.
•
In the NIV mode only apnea ventilation with pressure control is available.
Conflict of parameters:
•
At the change of ventilation parameter, conflict with other parameters in the edit row or
associated parameter window can occur. Test of parameter correctness is made on the each
step of setting. For instance, increasing of respiratory rate can lead to situation when I:E is
out of allowable range with the same inspiratory time.
•
The type of conflict is reflected by the color of conflicting parameter.
•
Yellow color indicates a medium priority conflict. The device can take this parameter for
execution, but warns about incorrect parameter. This situation occurs when the sensitivity of
the inspiratory pressure trigger exceeds PEEP. This means that the trigger will be activated
at the negative pressure in the circuit. Also problem can occur when user selects the
decreasing flow waveform and large flows during inspiration - because of the limitation of the
peak flow in the volume modes at 100 lpm flow waveform may differ from descending,
approaching to the rectangular.
•
Red color indicates a high priority conflict. The values of various parameters are mutually
exclusive. The device can not take this parameter for execution. The user must resolve the
conflict to change the mode. All ventilation modes have the same algorithm for informing
about conflict.
