Measurements and calculations
2
On the
MV/MR
,
AV/LVOT/AI
,
TV/TR
, or
PV
calculation list, tap
VTI
.
3
To trace manually:
a
Under the measurement name, tap the gear icon and select
Manual Trace
.
b
Drag the caliper to the start of the waveform, and lift your finger to start the trace.
c
Using your finger, trace the waveform.
To make a correction, trace backward on the dotted line.
d
Lift your finger to complete the trace.
e
Save the calculation: Tap
under the measurement name.
4
To trace automatically:
a
Under the measurement name, tap the gear icon and select
Auto Measure
.
A vertical caliper appears.
b
Drag the caliper to the beginning of the waveform.
c
Drag the second caliper to the end of the waveform and lift your finger.
The measurement results appear.
To calculate Right Ventricular Systolic Pressure (RVSP)
1
On a frozen Doppler spectral trace, tap
Calcs
.
If this control is hidden, tapping
More Controls
displays it.
2
On the
TV/TR
calculation list, tap
TR VMax
.
3
Position the caliper by dragging.
4
Save the calculation: Tap
under the measurement name.
To adjust the RA pressure (RAP)
1
On a frozen Doppler spectral trace, tap
Calcs
.
If this control is hidden, tapping
More Controls
displays it.
2
On the
TV/TR
calculation list, tap
RAP
.
3
Select the desired value from the RA list.
Note
This calculation requires the RA pressure. If RA pressure has not been adjusted,
the default value is used.
Note
Changing the RA pressure from the default value of 5 MmHG affects the RVSP
calculation result.
