10 - 6 BeneVision N1 Patient Monitor Operator’s Manual
• When using the Maximum Sensitivity setting, performance of "Sensor Off" detection may be
compromised. If the equipment and the sensor becomes detached from the patient, the potential
for false readings may occur due to environmental noise such as light, and vibration.
10.6.4 Changing Averaging Time (for Masimo SpO
2
)
The SpO
2
value displayed on the monitor screen is the average of data collected within a specific time. The
shorter the averaging time is, the quicker the monitor responds to changes in the patient’s oxygen saturation
level. Contrarily, the longer the averaging time is, the slower the monitor responds to changes in the patient’s
oxygen saturation level, but the SpO
2
measurement is more stable. For critically ill patients, selecting a shorter
averaging time will help with understanding the patient’s state.
To set the averaging time, follow this procedure:
1. Select the SpO
2
numeric area or waveform area to enter the SpO2 dialog.
2. Select the
SpO2 Setup tab.
3. Set
Averaging.
10.6.5 Monitoring SpO
2
and NIBP Simultaneously
When monitoring SpO
2
and NIBP on the same limb simultaneously, you can switch on NIBP Simul to lock the
SpO
2
alarm status until the NIBP measurement ends. If you switch off NIBP Simul, low perfusion caused by NIBP
measurement may lead to inaccurate SpO
2
readings and therefore cause false physiological alarms.
To set the
NIBP Simul, follow this procedure:
1. Select the SpO
2
numeric area or waveform area to enter the SpO2 dialog.
2. Select the
Alarm tab.
3. Set
NIBP Simul.
10.6.6 Changing the Sweep Speed of the Pleth Waveform
To set the sweep speed of Pleth waveforms, follow this procedure:
1. Select the SpO
2
numeric area or waveform area to enter the SpO2 dialog.
2. Select the
SpO2 Setup tab.
3. Set
Speed.
10.7 Changing the PR Settings
10.7.1 Changing the PR Alarm Settings
To change the PR alarm settings, follow this procedure:
1. Select the SpO
2
numeric area or waveform area to enter the SpO2 dialog.
2. Select the
PR Alarm tab.
3. Enter the password if required. For more information refer to
21.12.3Selecting Password for User
Authentication.
4. Set the alarm properties as desired.
10.7.2 Changing the QRS Volume
If the Alarm Source is set to PR, the QRS tone is derived from PR measurements. To set the QRS volume, follow
this procedure:
1. Select the SpO
2
numeric area or waveform area to enter the SpO2 dialog.
2. Select the
PR Setup tab.
