SQI with five highlighted bars indicates the best signal. SQI with one highlighted bar indicates the poorest signal.
If the SQI is poor, check ECG electrodes or SpO
2
sensor application. Reposition the electrodes or sensor if
necessary.
The CrozFusion
TM
function analyzes the ECG signal and the Pleth wave signal together to achieve more accurate
arrhythmia analysis result and HR/PR measurements. To view the on-screen help for the CrozFusion
TM
function,
select the
CrozFusion
tab from the
ECG
menu.
The ECG SQI, Pleth SQI, and signal fusion status are displayed when the CrozFusion
TM
function is enabled. The
following table lists SQI indications of different signal fusion status:
If the CrozFusion
TM
function is disabled, ECG signal and the Pleth wave signal will not be analyzed together, and
the ECG SQI and Pleth SQI are not displayed. For more information, see
10.6.6 Disabling the CrozFusion
.
NOTE
•
The ECG numeric area and waveform area are configured to be different for different lead type and
ECG settings.
•
The CrozFusion
TM
function uses ECG arrhythmia analysis leads according to the Analysis Mode
setting. So the ECG SQI indicates the signal quality of the ECG arrhythmia analysis leads.
(1) ECG lead label of the displayed waveform. When 6-lead placement is used to derive 12-lead ECG (D12L), all
derived leads are marked with a “d” in front of the lead label, for example “dV1”.
(2) ECG waveform gain
(3) ECG filter mode
(4) Notch filter status
(5) Paced status: If
Paced
is set to
Yes
,
is displayed. If
Paced
is set to
No
,
is displayed.
(6) HR/PR alarm message
(7) Pace pulse mark: If
Paced
is set to
Yes
, the pace pulse markers “|” are displayed corresponding to detected pace
pulse on each ECG waveform.
(8) Parameter label
(9) HR unit
(10) HR alarm limits
(11) HR value
(12) ECG signal quality index (ECG SQI)
(13) Pleth signal quality index (Pleth SQI)
The quality of both ECG and Pleth signal is good. ECG signal and Pleth signal are independently
analyzed.
The quality of Pleth signal is poor. The PR value may be erroneous. The ECG signal is being used to
correct the PR value.
The quality of ECG signal is poor. The HR value and arrhythmia analysis may be erroneous. The
Pleth signal is being used to correct the HR value and for arrhythmia analysis.
