HemoSphere Advanced Monitor 9 HemoSphere Swan-Ganz Module Monitoring
NOTE SV, EDV, and RVEF values are dependent on accurate heart rate calculations. Care
should be taken that accurate heart rate values are being displayed, and that double
counting should be avoided, especially in case of AV pacing.
If the patient has an atrial or atrial-ventricular (AV) pacer, the user should assess for the presence of double
sensing (for accurate HR determinations, only one pacer spike or one contraction per cardiac cycle should
be sensed). In the event of double sensing, the user should:
• Reposition the reference lead to minimize atrial spike sensing
• Select appropriate lead configuration to maximize HR triggers and minimize atrial spike sensing,
and
• Assess appropriateness of milliamperage (mA) pacing levels.
The accuracy of continuous EDV and RVEF determinations is dependent upon a consistent ECG signal
from the bedside monitor. For additional troubleshooting, see table 13-8, “HemoSphere Swan-Ganz module
EDV and SV faults/alerts,” on page 175 and table 13-12, “HemoSphere Swan-Ganz module general
troubleshooting,” on page 179.
If EDV monitoring is stopped, by touching the stop monitoring icon , the parameter globe target
indicator for EDV and/or RVEF will become gray, and a time stamp will be placed below the value
indicating the time that the last value was measured.
NOTE Pressing the stop monitoring icon will stop EDV, RVEF and CO monitoring.
If EDV monitoring is resumed, a gap will appear in the plotted line of the trend graph indicating the time
period when continuous monitoring was interrupted.
9.4.5 STAT EDV and RVEF
A hemodynamically unstable thermal signal may delay the HemoSphere advanced monitor from displaying
an EDV, EDVI and/or RVEF value after monitoring has been initiated. The clinician may use the STAT
values, which presents estimates of EDV or EDVI, and RVEF values updated approximately 60 seconds.
Select sEDV, sEDVI, or sRVEF as a key parameter to view STAT values. EDV, EDVI, and RVEF values
can be graphically trended over time alongside numerical values of sEDV, sEDVI, and sRVEF using the
graphical/tabular trends split screen monitoring view. Up to two parameters can be viewed in tabular format
on this screen. See Graphical/Tabular Trends Split on page 72.
9.5 SVR
While performing CO monitoring, the HemoSphere advanced monitor can also calculate SVR by utilizing
MAP and CVP analog pressure signal inputs from a connected patient monitor. See Analog Pressure Signal
Input on page 95.
