24 - 6 BeneVision N22/N19 Patient Monitor Operator’s Manual
The reference loops and the time at which the reference loops are saving display in the Loops window
simultaneously. Up to four groups of loops can be saved as reference loops. If the fifth group of loops needs to be
saved as reference, the monitor will prompt that an older group of reference loops should be replaced by the fifth
group.
24.7.3 Displaying the Reference Loop
The reference loop and real time loop can be displayed in the same area of the Loops window. In this case, the
reference loop is drawn in white. To display the reference loop, follow this procedure:
1. Select the numeric area or waveform area of Paw, Flow or Vol to enter the
RM menu.
2. Select
Loops from the bottom of the menu to enter the Loops window.
3. Select the reference loop to be displayed.
4. Select
Display Reference.
To hide the reference loop, select
Hide Reference button in the Loops window.
24.7.4 Adjusting the Loop Scale
The scales of the loops are the same as the scale of the corresponding waveforms. For more information, see
24.8.5 Changing the Wave Scale.
24.7.5 Selecting the Parameters for Display
The parameters displayed in the Loops window are the same as those displayed in the Paw, Flow and Vol numeric
areas. For more information, see
24.8.8 Setting Parameters for Display.
24.8 Changing RM Settings
24.8.1 Changing RM Alarm Settings
To change the RM alarm settings, follow this procedure:
1. Select the numeric area or waveform area of Paw, Flow or Vol to enter the
RM menu.
2. Select the
Alarm tab.
3. Set the alarm properties of PEEP, PIP and MVe:
â—† Switch on or switch off the alarms for PEEP, PIP and MVe.
â—† Adjust the alarm limits and alarm priority for PEEP, PIP and MVe.
â—† Switch on or switch off the alarm recording for PEEP, PIP and MVe.
24.8.2 Setting the Apnea Alarm Delay
The monitor will alarm if the patient has stopped breathing for longer than the previously set apnea time. To
change the delay time of the apnea alarm, follow this procedure:
1. Select the numeric area or waveform area of Paw, Flow or Vol to enter the
RM menu.
2. Select the
Alarm tab.
3. Set
Apnea Delay.
• The respiration monitoring does not recognize the cause of apneas. It only indicates an alarm if no
breath is detected when a preadjusted time has elapsed since the last detected breath. Therefore, it
cannot be used for diagnostic purposes.
