Summit Doppler Vista AVS L500VA
Manufactured by Summit Doppler
Summit Doppler Vista AVS
(Advanced ABI/Vascular System includes: on-screen guide, PVR, 8MHz Doppler, PPG, auto-cluff inflation/deflation, individual site mode, PC software, stand, and 9 cuffs) L500VA
Vista Series Dopplers offer more modalities for quickly obtaining the Ankle Brachial Index (ABI) and aiding in the detection of Peripheral Arterial Disease (P.A.D.). The Vista AVS system performs segmental exams, to help locate blockages or narrowing in the vessels after initial single-level ABI testing.
The Vista systems feature:
• Fast, automatic cuff inflation/deflation and highly accurate ABI calculations
• Graphic waveform display with easy to follow test sequences
• Sensitive bi-directional 8 MHz Doppler probe for surface vessels or optional 5 MHz probe for deeper vessels (Bi-directional probes are capable of obtaining waveforms)
• Obtains dual-ankle pressures at Posterior Tibial (PT) and Dorsalis Pedis (DP) arteries
• Pulse volume recording (PVR) can be used to obtain peripheral arterial waveforms with blood pressure cuffs
• PPG probe standard for performing TBI exams on patients with non-compressible arteries as well as at the toe site for segmental studies
• Software for reporting, annotating, storage, printing, and interfacing with EMR (optional feature on the Vista ABI)
Vista ABI System: Performs single-level ABI exams with the option to add PPG probe for TBI and comes with 4 blood pressure cuffs ((2) 10 cm and (2) 12 cm).
Vista AVS System: Next-level system performs a total of four exam types, including single-level ABI, seated ABI, TBI, and Segmental exams and comes with 9 blood pressure cuffs ((2) 10 cm, (4) 12 cm, (2) 17 cm, and (1) digital cuff).
