Arms : 80 - 220 mmHg
Ankles : 55 - 205 mmHg
ABI Dopplex Ability provides valid ABI results for at least
80% of the patients tested. Valid results consist of both
compressible vessels (where Dopplex Ability agrees
with the Doppler method to ± 0.28 for the 95% limits of
agreement), and incompressible vessels.
PVR Dopplex Ability provides fi ltered PVR waveforms from the
ankles with -3dB cut-off frequencies at 0.35 Hz and
10 Hz.
