New feature: SV, SVI, SVV Display and Trending Overview SV, SVI, and SVV can now be displayed in the CO Frame or Oximetry Frame. They must be configured as secondary parameters as described below. When monitoring SV, SVI, and/or SVV, the Vigileo monitor continuously displays the secondary CO Frame and/or Oximetry Frame parameter. SV, SVI, and SVV are time-averaged values and are calculated at approximately 20-second intervals. SV is displayed in milliliters/beat (ml/b), SVI is displayed in milliliters/beat/body surface area (ml/b/m2), and SVV is displayed in percent (%). Selecting Secondary Parameters Use the CO Menu or the Oximetry Menu to configure a secondary parameter to the desired frame. The CO Menu is displayed when the CO Frame is selected and the Oximetry Menu is displayed when the Oximetry Frame is selected. Select the Parameter option. Selecting SV, SVI, or SVV will configure the secondary parameter and update the frame. The screen displayed in the Multipurpose Frame will also be updated to reflect the change in configuration. Limit alarms monitoring will be activated on the displayed parameter and inactivated on the removed parameter.

NOTE
SV, SVI, and SVV are all CO Monitoring related parameters. Therefore, all of the conditions necessary to monitor CO/CI are also necessary to monitor SV, SVI, and SVV. The Patient Data and Zero Arterial Pressure can be selected on the CO Frame and performed while one of these secondary parameters is configured in order to start monitoring.
NOTE
If Oximetry has been calibrated and is being monitored, then it will continue monitoring in the background if SV, SVI, or SVV is being displayed in the Oximetry Frame.

Update to Chapter 6, Section 6.2, CO Frame Additional Information If SVV is configured to the CO Frame, the SVV Filtering Exceeded Indicator symbol “ “ will be displayed in the Frame when a high degree of pulse rate variability that could affect the SVV value is detected. The FloTrac algorithm will typically filter a certain amount of pulse rate variability which may be a result of arrhythmias (i.e. up to 2 aberrant beats every 20 seconds); therefore, the symbol signifies that the amount of variability has exceeded the algorithm’s capacity for filtering.
Update to Chapter 7, Section 7.2, Oximetry Frame Additional Information If SVV is configured to the Oximetry Frame, the SVV Filtering Exceeded Indicator symbol “ “ will be displayed in the Frame when a high degree of pulse rate variability that could affect the SVV value is detected. The FloTrac algorithm will typically filter a certain amount of pulse rate variability which may be a result of arrhythmias (i.e. up to 2 aberrant beats every 20 seconds); therefore, the symbol signifies that the amount of variability has exceeded the algorithm’s capacity for filtering.

In addition, if the SVV parameter is displayed, its box will contain the SVV Filtering Exceeded Indicator symbol “ “ when a high degree of pulse rate variability that could affect the SVV value is detected. The FloTrac algorithm will typically filter a certain amount of pulse rate variability which may be a result of arrhythmias (i.e. up to 2 aberrant beats every 20 seconds); therefore, the symbol signifies that the amount of variability has exceeded the algorithm’s capacity for filtering. When the symbol is displayed, the value will be displayed in yellow.
Update to Chapter 10, Section 10.6, Tabular Trends Addition to the first paragraph of the Tabular Trends section as follows: Use Tabular Trends to review the patient’s past parameter values. The parameter values are shown in table format with the values for each parameter arranged by time. Up to five parameters are contained in the table. If the SVV parameter is displayed, each value box will contain the SVV Filtering Exceeded Indicator symbol “ “ when a high degree of pulse rate variability that could affect the SVV value is detected. The FloTrac algorithm will typically filter a certain amount of pulse rate variability which may be a result of arrhythmias (i.e. up to 2 aberrant beats every 20 seconds); therefore, the symbol signifies that the amount of variability has exceeded the algorithm’s capacity for filtering. When the symbol is displayed, the value will be displayed in yellow.
