HemoSphere Advanced Monitor 9 HemoSphere Swan-Ganz Module Monitoring
Connect the other end of the interface cable to the bedside monitor’s ECG signal output. This will provide
an average heart rate (HR
avg
) measure to the HemoSphere advanced monitor for EDV and RVEF
measurements. For compatible ECG cables, contact your local Edwards representative.
IMPORTANT NOTE The HemoSphere advanced monitor is compatible with an ECG
analog slave input from any external patient monitor that has an
analog slave output port which meets the ECG signal input speci-
fications identified in appendix A, table A-4 of this operator’s
manual. The ECG signal is used to derive heart rate which is then
used to calculate additional hemodynamic parameters for display.
This is an optional feature that does not impact the HemoSphere
advanced monitor’s primary function of monitoring cardiac output
(with the HemoSphere Swan-Ganz module) and venous oxygen
saturation (with the HemoSphere oximetry cable). Device perfor-
mance testing was conducted using ECG input signals.
WARNING PACEMAKER PATIENTS – Rate meters may continue to count the pacemaker rate
during occurrences of cardiac arrest or some arrhythmias. Do not rely entirely upon
displayed heart rate. Keep pacemaker patients under close surveillance. See table A-4
on page 191 for disclosure of the pacemaker pulse rejection capability of this
instrument.
For patients requiring internal or external pacing support, the HemoSphere advanced
monitoring platform should not be used to obtain heart rate and heart rate derived
parameters under the following conditions:
• pacer pulse synch output from bedside monitor includes the pacer pulse, however,
the characteristics are outside of the pacemaker pulse rejection capabilities
specifications as listed in table A-4.
• pacer pulse synch output characteristics from bedside monitor cannot be
determined
Note any discrepancies in heart rate (HRavg) with the patient monitor HR and ECG
waveform display when interpreting derived parameters such as SV, EDV, RVEF, and
associated index parameters.
ECG signal input and all parameters derived from heart rate measurements have not
been evaluated for pediatric patients and are therefore not available for that patient
population
NOTE When an ECG input connection or disconnection is first detected, a brief notification
message will be displayed on the status bar.
SV is available with any compatible Swan-Ganz catheter and an ECG signal input. For
EDV/RVEF monitoring, a Swan-Ganz CCOmbo V catheter is required.
