Results
a
HR needed for CO. You can enter the HR measurement on the patient form, or by measuring in M Mode or Doppler
(see page 3).
b
Performed at 300 cm/s on the negative side of the baseline.
c
The AVA by VMax measurement requires the LVOT D, LVOT VMax, and AV VMax measurements. The AVA by VTI
measurement requires the LVOT D, LVOT VTI, and the AV VTI measurements.
d
Uses default RA pressure if not supplied.
e
Need to measure E (MV measurement) to get E/e’ ratio.
