Methodology and Monitoring
2 Touch the scroll buttons to set the Alarm/Target values.
3 Touch the Enter button to save the values.
Central Venous Pressure
Manual Entry
To calculate SVR/SVRI and assess patient hemodynamic
afterload status, a CVP value must be entered.
1 Touch the Clinical Actions button.
2 Touch CVP Entry.
3 Enter a CVP value.
4 Touch the Home button.
Continuous Waveform
Display
The blood pressure waveform can be checked through the
Zero & Waveform screen or through the graphical trend
screen.
See “Arterial Waveform (ART) Display” on page 5-3.
Output Signal to Patient
Monitor
The Zero & Waveform screen provides the user with the
option to send the arterial waveform signal to a bedside
patient monitor.
1 Connect the patient monitor adaptor cable from the back
of the Pump-Unit to the patient monitor cable.
2 Touch the Zero patient monitor button and
then zero the patient monitor.
3 Touch the Signal button of the Pressure
Output Selection to begin pressure signal
output.
Derived Value Calculator
Select the Derived Value Calculator option to
compute the patient’s DO
2
, VO
2
, SVR or CPO.
The Derived Value Calculator provides a conve-
nient way to display these parameters for a one-
time calculation. For more information, see
“Derived Value Calculator” on page 10-1.
Cuff Options
The Cuff Options screen allows the user to select the time
interval between cuff pressure release and the switching time
interval for double cuff monitoring. This screen also displays
sensor status and information for connected Cuff(s) and HRS.
1 Touch the Clinical Actions button.
2 Touch More.
3 Touch Cuff Options.
4 For Single Cuff monitoring, select a cuff pressure
release time interval from the available option list. At the
end of the cuff pressure time release interval, the pressure
will be released from the cuff for a duration indicated by
the countdown timer on the information bar. See “Cuff
Pressure Release Mode” on page 7-9.
5 For Double Cuff monitoring, select a switching time
interval from the available option list.
WARNING
Physiological visual and audible physiological alarms
are activated only if the parameter is selected and
displayed on the screens as a key parameter (1-4
parameters). If a parameter is not selected and
displayed as a key parameter, the audible physiological
alarms are silenced.
WARNING
Do not use the EV1000 Clinical Platform NI as a heart
rate monitor.
CAUTION
The pulsations from intra-aortic balloon support can be
additive to the pulse rate on the instrument pulse rate
display. Verify patient's pulse rate against the ECG
heart rate.
CAUTION
The pulse rate measurement is based on the optical
detection of a peripheral flow pulse and therefore may
not detect certain arrhythmias.The pulse rate should
not be used as a replacement or substitute for ECG
based arrhythmia analysis.
WARNING
The analog output signal from the EV1000 Clinical
Platform NI will experience brief interruptions due to
Physiocal which will be displayed on the bedside patient
monitor.
